Notice of Intended Prosecution (NIP) explained
A Notice of Intended Prosecution is an early warning, not a conviction. Its 14-day service rule can matter, but the separate 28-day section 172 driver-identification duty is crucial: ignoring, delaying or guessing can create a more serious problem.
Who this applies to
The law explained
A Notice of Intended Prosecution is governed principally by section 1 of the Road Traffic Offenders Act 1988. For offences to which that provision applies, a person cannot normally be convicted unless they were warned at the time that prosecution was being considered, served with a NIP, or served with a summons or charged within 14 days of the alleged offence. In practical terms, a postal NIP tells the recipient the nature of the allegation and gives the date, time and place sufficiently clearly for them to investigate and recall the event.
The purpose of the rule is fairness. Prompt warning gives a motorist a reasonable chance to remember who was driving, inspect the location, preserve relevant material and identify any genuine issue. It is not a general rule requiring police to prove the whole allegation within 14 days. It is an initial notification requirement which applies only to specified offences and is distinct from later procedural steps, including identifying the driver, issuing a fixed penalty offer, or starting a prosecution.
In a camera-led case, the first NIP is normally sent to the registered keeper identified from DVLA records. The important address is the keeper's last known address on that record. Service can be effective where the notice was correctly posted to that address within the required period, even if the keeper sees it later or does not receive it. An address problem caused by failure to update the vehicle record will therefore usually prevent reliance on late or missed delivery. A notice sent on to a subsequently nominated driver does not itself have to meet the same 14-day requirement.
A NIP is commonly accompanied by a separate request made under section 172 of the Road Traffic Act 1988. This requires the keeper to provide information as to the identity of the driver when required by police. The section 172 duty is independent of the allegation for which the NIP was sent. A person can therefore face a failure-to-furnish allegation even where the prosecution later takes no action on the speeding, traffic-light or other underlying matter.
For a keeper, the prosecution must prove that a lawful request for driver information was made and that the required information was not provided. The keeper may have a defence where they did not know, and could not with reasonable diligence have found out, who the driver was. That is a fact-specific safeguard rather than a right simply to say that several people might have driven. Courts generally look at the practical enquiries made, the information available, and whether those enquiries were made promptly and documented.
The 14-day NIP requirement also has limits. No NIP is required where an accident occurred, because the collision is treated as adequate warning. It is also unnecessary where the driver was warned verbally at the time that prosecution was being considered, such as when stopped by an officer. There are further circumstances in which a failure to serve in time may not prevent a case, including where the police could not with reasonable diligence ascertain the keeper's name and address in time. The facts surrounding the vehicle record, police enquiries and method of service can therefore be important.
Complying with section 172 does not amount to accepting guilt for the original offence. It identifies the driver so that the allegation can be considered against the right person. Equally, disputing the original allegation does not remove the obligation to respond to a valid section 172 request. The two issues are often confused, and that confusion is a common reason why motorists acquire six points for a paperwork offence when the original allegation might have carried a lower penalty.
Deadlines you must not miss
14 days to serve the keeper
The NIP, or a summons, must normally be served on the registered keeper within 14 days of the alleged offence. This is usually relevant to the first notice sent to the keeper, rather than every later notice issued as the police work through a chain of keeper, lease company, employer and driver.
Service is judged by correct posting to the DVLA address, not simply by the day the recipient opened the letter. If a keeper moved but did not update the vehicle record, a notice sent to the old registered address will usually not create a successful late-service argument. Keep the envelope, note the delivery date and do not assume that an apparent delay ends the matter.
28 days to return the section 172 form
The request to identify the driver carries its own deadline, typically 28 days. Returning it late, unsigned or incomplete can be treated as a failure to provide the information, which is a separate offence. The requirement needs attention even where the recipient intends to dispute the alleged offence or believes the NIP was late.
The safest practical approach is to read the deadline printed on the notice, retain a complete copy of the response and use a reliable method of return. If the recipient is making enquiries because the driver is uncertain, those enquiries need to be carried out quickly; waiting until the deadline has expired can make a later reasonable-diligence argument much harder to establish.
Knock-on deadlines for the named driver
Once a keeper nominates a driver, the police may send that person a further section 172 request, a fixed penalty offer, a course invitation or court paperwork. Each document may have its own response period. The named driver should not assume that the original keeper's response resolves every administrative requirement.
In company, lease and hire arrangements, several notices may be issued before the driver is reached. Delays at any stage can leave less time for the next recipient. Accurate records and prompt forwarding of notices are therefore important, but forwarding a letter informally does not necessarily satisfy the legal recipient's own duty to reply.
6-month limit on starting proceedings
For summary offences, the prosecution must usually begin the case within six months of the offence. The NIP rule is a separate, earlier safeguard, so satisfying one does not remove the other. Both have to be met for many camera-led prosecutions.
Starting proceedings is not the same as the case being heard or concluded within six months. Equally, correspondence, a course offer or a fixed penalty process may continue before a court case is started. A person considering a time-limit point should preserve the documents and obtain advice on the particular allegation rather than relying on a general assumption about dates.
Deadlines on a court notice
If the matter proceeds to the magistrates' court, court papers will contain their own date for responding. This may be through the Single Justice Procedure for an offence capable of being dealt with in that way, or through a summons or requisition requiring engagement with the court process.
Ignoring court papers can result in the case being decided without the motorist's account being considered, subject to the applicable procedure. The court deadline is separate from the earlier 28 days for the section 172 request and must be read carefully.
Penalties
Failing to identify the driver
The headline risk of mishandling a NIP is the section 172 offence: 6 penalty points and a fine of up to £1,000 for failing to give driver information. This can arise from ignoring the form, responding too late, giving an incomplete response, or returning a response that is not properly completed.
The offence is separate from the original allegation. It can consequently be charged where the prosecution does not proceed with speeding or another alleged offence. Six points can be more damaging for insurance and licence purposes than a lower-level underlying allegation, particularly for a driver with existing endorsements or limited driving history.
Penalties for the underlying offence
If the driver is correctly identified and the case proceeds, the outcome depends on the alleged offence and its seriousness. For speeding that is typically 3 points and a £100 fixed penalty or a court fine in Bands A to C; for other offences the relevant guideline applies. Eligibility for a diversionary course or fixed penalty is not automatic and depends on the facts and the police's decision.
Where a case reaches court, sentence can reflect factors such as the extent of any excess speed, road and traffic conditions, driving standards, risk created, previous relevant convictions and personal mitigation. Court proceedings can also involve financial orders in addition to the main fine. A NIP itself does not impose any of these consequences.
Court fines for the section 172 offence
If a failure-to-furnish allegation goes to court rather than being dealt with by fixed penalty, the fine is set against the person's means up to the statutory maximum, and the six points are endorsed on conviction. This can be heavier than the original offence would have been.
The court will consider the circumstances of the non-response, including whether there was a genuine attempted reply, whether the recipient had clear notice of the request, and any evidence supporting a statutory defence. A deliberate refusal, an unexplained failure to engage or an unsupported claim of uncertainty is likely to be treated very differently from a well-evidenced inability to identify the driver despite reasonable diligence.
Totting-up exposure
Because the section 172 offence adds six points in one hit, it can push a driver towards or past 12 points within three years, raising the prospect of a totting-up disqualification. The relevant court process considers the driver's points record at the time of sentence.
Exceptional hardship can be relevant when a court is considering whether a totting-up disqualification should be imposed, but it is not a defence to the underlying points offence and it is not automatic. The consequences for others, as well as the driver, may be considered. Drivers facing this position commonly need tailored advice because the precise record and circumstances matter.
Company keeper liability
Where the keeper is a company, the business has the duty to identify the driver and faces a fine if it fails to do so. A nominated company officer may be required to give the information, and corporate fines for non-compliance can be substantial.
A company does not receive penalty points because it does not hold a driving licence, but its failure can still lead to prosecution and financial consequences. Internal fleet records, vehicle allocations, booking systems and a clear process for dealing with post are important evidence where the business has to show what information it could provide.
Insurance and licence consequences
Penalty points are recorded on the driving record and insurers commonly ask about convictions, endorsements and pending prosecutions when arranging or renewing cover. The policyholder must answer the insurer's questions accurately. The effect on premium, excess or availability of cover varies between insurers and cannot be predicted from the NIP alone.
Drivers in the first two years after passing their first driving test should be alert to the new-driver rules, which operate separately from the usual totting-up regime. Six points for a section 172 conviction may therefore have especially serious licensing consequences for a newly qualified driver.
What happens, step by step
1. Detection and keeper lookup
After an alleged offence is recorded by a camera or observed by an officer, police may obtain the registered keeper's details from DVLA. The vehicle record, rather than the driving licence address, is normally central to where the first postal notice is sent.
An old V5C address can therefore cause a notice to be delivered to a previous home, employer or business address. The keeper may only discover the allegation when later correspondence, a court notice or a debt-enforcement issue arises.
2. NIP and section 172 request issued
The keeper receives the NIP together with, or alongside, a section 172 request. The NIP identifies the alleged offence, date, time and location and warns that prosecution is being considered. The request asks for driver information.
Recipients should distinguish the two functions. The NIP is the warning required for applicable offences; the section 172 form is the mechanism for establishing who was driving. One document may perform both functions, but the legal obligations are different.
3. Check the document and preserve basic evidence
The recipient can check the alleged date, time, location, vehicle registration, notice date and response deadline. Photographing the envelope and retaining all pages may be useful if service or timing later becomes relevant.
This check is not an invitation to delay. A recipient who believes information is wrong, or who wants clarification, still needs to address the section 172 requirement within the stated period unless and until the police confirm otherwise.
4. The keeper identifies the driver or makes enquiries
The keeper identifies the driver, whether themselves or another person, signs the declaration and returns it within the deadline. If the keeper does not know, the law expects reasonable diligence to find out, such as reviewing diaries, work records, mileage, fuel purchases, key access, messages or other available material.
The response must be truthful. A keeper should not guess between possible drivers or agree to name a person who was not driving. Notes of enquiries made at the time can become important if identity remains unresolved.
5. Further notices may follow
Where another person is named, police may send that person a further request to confirm the information. This is common where a vehicle is owned by a lease company, hired to a business, allocated to an employee or shared within a household.
Each recipient should deal with their own notice. A chain of nominations can be legitimate where it reflects the actual vehicle arrangements, but it should not be used to obstruct the process or postpone a genuine identification.
6. The identified driver receives a disposal decision
Once the driver is identified, the police may take no further action, offer a course where available, offer a conditional fixed penalty or begin court proceedings. What is offered depends on the alleged offence, the evidence, any relevant policy and the driver's circumstances.
Accepting or declining a later offer is a separate decision from completing the section 172 form. The driver should read that later document closely because it will state its own conditions and deadline.
7. Service and identity issues are considered
If there is a genuine issue about whether the first NIP was served in time, it may be raised in relation to the prosecution for the underlying offence. The outcome depends on the service facts, including address accuracy and posting, not solely on when the recipient recalls seeing the letter.
If the issue is inability to identify the driver, the focus is usually on the section 172 duty and whether reasonable diligence was exercised. The documentary trail of enquiries can be more persuasive than a general assertion that the keeper cannot remember.
8. Court procedure if the matter is not resolved
Contested underlying allegations and failure-to-furnish allegations are dealt with in the magistrates' court. Some cases begin through the Single Justice Procedure. The recipient must respond to court papers by the stated date and can explain their position through the available procedure.
The prosecution must prove the relevant offence. For a section 172 matter, that includes proving the request and failure to provide information, while any applicable statutory defence may be raised on the facts. A conviction can result in points, a fine and other court financial consequences.
Practical steps to take now
Keep your DVLA address up to date
Update both the vehicle log book (V5C) and driving licence address when moving. The first NIP normally goes to the registered keeper address, and an outdated V5C is a frequent reason why a motorist does not see a notice until it is too late to deal with easily.
Record the delivery details immediately
Photograph the envelope, postmark and all pages of the notice, and make a note of the date it was found or delivered. This preserves potentially relevant information about service while it is still available.
Read both the allegation and the request
Check the vehicle registration, date, time, location and deadline, but distinguish between the NIP and the section 172 requirement. A disagreement about speed or the quality of the evidence does not usually justify leaving the driver-identification form unanswered.
Identify the driver honestly and precisely
If the driver is known, provide the requested details accurately. Check spelling, address and licence information where requested. Accurate information reduces the risk of further avoidable notices and demonstrates that the keeper has engaged with the statutory duty.
Make and document genuine enquiries
Where the vehicle had more than one possible driver, check calendars, work rotas, booking records, fuel receipts, telematics, dashcam footage, phone records and messages. Ask everyone who had access to the keys. Keep a dated note of what was checked and what each possible driver says.
Return the form within 28 days, properly completed
Treat the stated 28 days as a hard administrative deadline. Complete all relevant sections and ensure the form is signed where it requires a signature. An unsigned, incomplete or late response can be treated as a failure to furnish information.
Keep a full copy and proof of return
Keep a scan or photograph of the completed response and evidence of posting or delivery. If there is later a dispute about whether a reply was made, contemporaneous records are far more useful than recollection alone.
Separate the response from any challenge
A service argument, factual defence or complaint about the allegation may need to be raised later, but the section 172 response is a distinct matter. Dealing with driver identification while preserving the evidence for a challenge avoids turning one disputed allegation into a separate six-point offence.
Get focused help where the consequences are serious
Seek informed advice promptly if the driver cannot genuinely be identified, the NIP may be out of time, the keeper is a company, or points could lead to disqualification or new-driver licence revocation. Early advice leaves time to gather evidence without allowing a deadline to expire.
Common mistakes
Assuming a late NIP wins automatically
People often count 14 days from the alleged offence to the day they opened the letter and assume the case must end. The rule is more technical: correct posting to the DVLA-registered address is highly significant, and there are statutory exceptions.
Relying on a late-looking notice without preserving the envelope, checking the V5C record or responding to section 172 can result in a separate failure-to-furnish prosecution. Timing may be a valid issue, but it is not an automatic answer.
Ignoring it because someone else was driving
A registered keeper may think the notice is irrelevant because they were at home, at work or otherwise not driving. That misunderstands section 172: the initial recipient's role is often to identify the actual driver.
Ignoring the form can lead to six points and a fine even if the named vehicle was driven by a spouse, child, colleague or friend. The correct approach is to provide truthful information about the person who was driving.
Returning an unsigned or incomplete form
Recipients can focus on the identity details and overlook a declaration, signature or required field. They may assume an unsigned form at least shows that they tried to cooperate.
An unsigned or incomplete response can be treated as no valid response, exposing the keeper to the section 172 allegation. A final check and retaining a copy reduces this avoidable risk.
Waiting for photographs before replying
It is understandable to want photographs or further evidence before naming a driver, particularly if several people used the vehicle. But a request for information does not normally suspend the 28 days for responding.
Delaying until evidence arrives can cause the deadline to pass. The keeper needs to make reasonable enquiries using available material and deal with the statutory request, while keeping any evidential concerns for the appropriate later stage.
Saying 'I cannot remember' without enquiries
Memory can genuinely fade, especially with shared cars or delayed correspondence. However, reasonable diligence requires more than a bare assertion of uncertainty.
Without records of checks, questions asked and material considered, a court may conclude that the keeper did not do enough to identify the driver. Prompt, documented enquiries are central to any realistic reasonable-diligence defence.
Naming someone falsely
Some motorists believe that a willing relative or friend can take points in order to protect the actual driver. Others make a speculative nomination to avoid a section 172 penalty.
Nominating a person who was not driving can amount to perverting the course of justice, a serious offence that can lead to a prison sentence. The form must be completed honestly, even where the consequences of identifying the actual driver are unwelcome.
Confusing the V5C with the driving licence
Drivers sometimes update the address on their driving licence but not the vehicle log book, believing that DVLA will use one record for everything. The registered keeper information associated with the vehicle is what normally drives the first NIP process.
The result can be valid correspondence going to a previous address while the driver assumes their records are current. Updating both records is the practical safeguard.
Leaving company notices in an internal post tray
Businesses may receive notices at a registered office, accounts department or vehicle-management address rather than the location where the vehicle user works. Staff can mistakenly treat the letter as routine post and fail to escalate it.
The company itself has obligations as keeper, and internal delay can produce a prosecution and fine. A clear procedure for logging, allocating and responding to motoring notices is important for every fleet operator.
When to get professional help
Many straightforward notices can be dealt with by accurately naming the driver and returning the form within the stated period. Independent legal advice can be useful where the first NIP appears to have been served outside the 14-day period, especially if the V5C address was correct at the time. The envelope, the date of the alleged offence, the date on the notice, any evidence of posting and the precise DVLA record may all matter. A late-looking letter alone is not necessarily enough to establish a valid timing argument.
Advice is particularly valuable where the keeper genuinely cannot identify the driver after making real enquiries. This can arise with shared family cars, pool vehicles, long journeys, company fleets, hire arrangements or an allegation received after a delay. The reasonable-diligence defence is evidence-led. A solicitor can explain the relevant legal test and help assess whether records such as booking logs, calendars, fuel transactions, telematics, phone data, messages or key-control information support the account.
Prompt assistance may also be appropriate where the underlying allegation could lead to disqualification, where the recipient already has points, or where a section 172 conviction would take the total to or beyond 12 points within three years. New drivers should also understand the separate consequences that may follow if their licence is revoked under the new-driver regime after accumulating the relevant number of points. These consequences can make an apparently routine notice much more significant.
Specialist help may be needed if a company, partnership, fleet operator, lease provider or hire business receives the notice, or if a person is being asked to name a driver but believes the information is inaccurate. No one should invent an answer or nominate a person merely because that person is willing to accept points. False nominations can have consequences far beyond the original motoring allegation.
Frequently asked questions
What exactly is a Notice of Intended Prosecution?
A NIP is a formal warning that police are considering prosecution for an alleged motoring offence. For offences covered by section 1 of the Road Traffic Offenders Act 1988, it is one way of giving the prompt notice required before conviction. It normally identifies the allegation, date, time, location and vehicle.
It is not a conviction, a fine or penalty points. In camera cases it commonly arrives with a section 172 request requiring the recipient to identify the driver, which is a separate legal obligation.
Does a NIP have to arrive within 14 days?
The first NIP, or a summons, must normally be served on the registered keeper within 14 days of the alleged offence. The rule applies to offences within section 1 and is subject to exceptions.
What matters is not always the date the keeper opened the letter. Correct posting to the keeper's last known DVLA address is important, and an address that was out of date can defeat an argument based on non-receipt or apparent lateness.
What if the NIP arrives after 14 days?
Genuine late service can prevent conviction for an offence for which a NIP is required, but the facts must be examined carefully. Keep the envelope and notice, record when it arrived, and check whether the V5C address was correct at the relevant time.
A late-looking notice does not remove the section 172 requirement. The recipient still needs to provide driver information within the stated period unless there is a clear basis not to do so. The timing issue and the identification duty are separate.
Do I have to say who was driving?
Normally, yes. Section 172 of the Road Traffic Act 1988 requires a keeper to give driver information when lawfully required by police. The duty applies even where the keeper was not driving and even where the underlying allegation is disputed.
Failure to provide the information can carry 6 penalty points and a fine of up to £1,000. The recipient should provide information honestly; the form is not a mechanism for challenging the alleged speed or other substantive allegation.
What if I genuinely do not know who was driving?
There can be a defence if the keeper did not know and could not, with reasonable diligence, find out who the driver was. This is not satisfied merely by saying that the keeper cannot remember or that several people had access to the car.
Relevant enquiries may include checking calendars, work shifts, fuel transactions, telematics, dashcam footage, phone records, booking records and messages, and asking every possible driver. A dated record of those enquiries is important because the issue is likely to be judged on the evidence available.
Is a NIP the same as a fine, fixed penalty or Speed Awareness Course offer?
No. A NIP is an early warning that prosecution is being considered. The accompanying section 172 form identifies the driver. Neither document itself imposes a fine, points or a course requirement.
Once the driver is identified, police may decide to take no further action, offer a course where available, offer a conditional fixed penalty, or start court proceedings. Those later documents have separate terms and response dates.
Does every speeding case need a posted NIP?
Many camera-detected speeding cases involve a posted NIP to the registered keeper. However, a posted notice is not required if the driver was warned verbally at the roadside that prosecution was being considered.
No NIP is required where an accident occurred, because the collision itself is treated as warning enough. The detailed NIP rule also applies only to the statutory offences it covers, so the absence of a letter does not always mean that no prosecution is possible.
Can I be prosecuted if I never received the NIP?
Possibly. A notice correctly posted to the registered keeper's last known DVLA address can be treated as served even if it was delayed, lost or not seen. This is especially relevant where the V5C was still registered to a former address.
If a recipient learns of the matter only later, they should retain evidence about their address history and the documents received. They should also deal promptly with any live section 172 or court paperwork rather than assuming non-receipt alone resolves the case.
What happens with a company car, leased vehicle or hire car?
The first notice may go to the registered keeper, which may be a leasing company, hire company or employer rather than the person driving. That organisation may identify the next relevant person, who may then receive a further notice or section 172 request.
A company as keeper has its own duty to provide available driver information and may be fined for failing to do so. Internal vehicle allocation records, hire agreements, booking logs and key-control systems can be important in establishing who used the vehicle.
Can the police send me a photograph before I name the driver?
Police may sometimes provide a photograph to assist with driver identification, but the purpose of the image is not necessarily to provide the prosecution's full evidence. The image may show the vehicle clearly without showing the driver's face.
A request for photographs does not normally stop the 28 days for the section 172 response. The keeper should continue reasonable enquiries and avoid letting the deadline pass while waiting for a reply.
Will six points for failing to furnish affect a new driver?
It can have particularly serious consequences. A section 172 conviction carries 6 penalty points, and drivers in their first two years after passing their first driving test are subject to the separate new-driver licensing regime.
The effect depends on the individual's existing record and licence history, but it can be much more severe than a routine fixed penalty. It is sensible to obtain timely advice where a new driver faces a section 172 allegation or any points that could affect their licence.
Do I need to tell my insurer about a NIP?
A NIP is an allegation and not a conviction or endorsement. Whether it must be disclosed immediately depends on the precise question asked by the insurer and the policy terms. Motorists should answer questions truthfully and not assume that all insurers ask the same thing.
Convictions and points are commonly relevant at renewal or when obtaining a new policy. A section 172 conviction, with six points, may affect premiums or cover options, but the financial effect varies between insurers.
Will the NIP appear on my DVLA driving record?
A NIP itself does not create an endorsement and does not mean that points appear on the driving record. It is only a notice and a request for information.
If the matter results in a fixed penalty accepted by the driver or a court conviction, any endorsement that applies is recorded. The keeper who simply identifies another driver does not receive points merely because the NIP was addressed to them.
Do these NIP rules apply in Scotland or Northern Ireland?
This page concerns England and Wales. The core statutory provisions discussed here are used across Great Britain, but procedure, prosecution practice and court processes can differ in Scotland. A Scottish case should be checked against Scottish law and local advice.
Northern Ireland has a separate legal system and different motoring legislation and procedures may apply. A recipient dealing with a Northern Ireland notice should not rely on this page as a complete statement of the rules there.
