Failing to stop after an accident is a criminal offence under section 170 of the Road Traffic Act 1988. It applies where a motor vehicle is involved in an accident on a road or other public place and injury or qualifying damage is caused. The duty to stop exists regardless of fault. Even minor incidents, such as scraping another vehicle in a car park or clipping a wing mirror, can trigger criminal liability.
Many motorists wrongly assume that the offence only applies to serious collisions. In reality, the statutory duty is broad. A driver who leaves the scene without stopping and providing details where required may face prosecution, penalty points, disqualification and even imprisonment. The offence is commonly referred to as “hit and run” in the media, but the legal framework is governed by section 170 RTA 1988.
What this article is about
This guide explains the law on failing to stop after an accident in the UK. It sets out when the legal duty arises, what drivers must do at the scene, when an accident must be reported to the police, and the penalties that may follow. It also examines sentencing guidelines, aggravating and mitigating factors, available defences and the time limits for prosecution. The focus throughout is on legal compliance and the real-world consequences for motorists.
Section A: The Legal Basis for Failing to Stop After an Accident
The offence of failing to stop after an accident is created by section 170 of the Road Traffic Act 1988. It is not dependent on fault, nor does it require dangerous driving. The duty arises simply because an accident has occurred owing to the presence of a mechanically propelled vehicle on a road or other public place, and that accident has caused injury or certain types of damage.
Understanding the statutory trigger is critical. Many motorists believe the duty only applies where they are to blame or where the damage is significant. That is incorrect. The legal obligation arises automatically if the statutory conditions are met.
1. What Is the Fail to Stop Offence?
Under section 170 RTA 1988, a driver must stop if an accident occurs owing to the presence of their mechanically propelled vehicle on a road or other public place and the accident causes personal injury to any person other than the driver, or qualifying damage.
The phrase “owing to the presence of a mechanically propelled vehicle” is deliberately wide. The vehicle does not need to collide directly with another object. It is sufficient that its presence caused or contributed to the accident.
For example:
- Swerving to avoid a vehicle and striking a wall may trigger the duty.
- Forcing a cyclist off the road without physical contact may still fall within scope.
The offence most commonly charged is “fail to stop”, but prosecutors frequently also charge “fail to report” where the driver did not report the incident within 24 hours when required. These are separate offences under section 170. Reporting within 24 hours does not “cure” a failure to stop if the driver did not stop at the scene in the first place.
Importantly, there is no requirement that the driver was negligent, careless or at fault. A completely blameless driver may still commit an offence by leaving the scene without complying with their statutory duties.
2. When Does the Duty to Stop Apply?
The duty to stop arises where injury or qualifying damage has occurred.
Personal injury
If personal injury is caused to any person other than the driver, the duty is engaged. This includes passengers in the driver’s vehicle, passengers in another vehicle, pedestrians, cyclists and motorcyclists. The injury does not need to be serious. Even relatively minor injury can satisfy the statutory threshold.
Damage to vehicles
Damage to another vehicle or its trailer will trigger the duty. The damage need not be extensive. Minor damage, such as a scratched bumper or broken wing mirror, is sufficient.
Injury or damage to animals
Section 170 specifies certain animals, including horses, cattle, asses, mules, sheep, pigs, goats and dogs. Damage to other animals, such as cats or wild animals, does not fall within the statutory list, although separate legal considerations may arise.
Damage to property
Damage to property on or adjacent to the road or public place will also trigger the duty. This may include fences, walls, street furniture, shopfronts or garden walls. The threshold is low. The statute does not require substantial damage.
3. What Counts as a Road or Public Place?
The offence applies only where the accident occurs on a road or other public place.
A “road” includes any highway and any other road to which the public has access.
A “public place” is broader and may include privately owned land if the public have access to it, whether as of right or by permission. Common examples include supermarket car parks, retail park parking areas, petrol station forecourts and fast-food drive-through lanes. The fact that land is privately owned does not prevent it from being a public place if members of the public are permitted to use it.
By contrast, purely private land to which the public do not have access, such as a gated private driveway or a secure industrial yard with controlled entry, may fall outside the scope of section 170. Whether a location qualifies as a public place is a question of fact and degree, often determined by the extent of public access at the relevant time.
Section A Summary
Failing to stop after an accident is a statutory offence under section 170 RTA 1988. The duty arises automatically when a mechanically propelled vehicle is involved in an accident on a road or public place and injury or qualifying damage occurs. Fault is irrelevant. The damage threshold is low. The location must be a road or public place, which commonly includes car parks and forecourts open to the public. Understanding when the duty is triggered is the first step in avoiding criminal liability.
Section B: Legal Duties After an Accident
Once the statutory conditions under section 170 RTA 1988 are met, a driver is under specific legal duties. These duties are separate and cumulative. A driver may comply with one but still commit an offence by failing to comply with another.
The obligations fall into three core categories: the duty to stop, the duty to provide details and the duty to report the accident (and in some cases to produce insurance). Failure to comply with any of these can result in prosecution for failing to stop after an accident or failing to report an accident.
1. The Duty to Stop
The first obligation is simple in principle but often misunderstood in practice.
A driver must stop if the accident falls within section 170. Stopping briefly and immediately driving away without engaging with those affected may not be sufficient. In practical terms, the driver must stop and remain at the scene for long enough to enable details to be exchanged if required.
Stopping means bringing the vehicle to a halt and remaining available to provide the required particulars. Driving off immediately, even if intending to return later, can amount to the offence of failing to stop.
There is no requirement that someone demands the driver stop before the duty arises. The obligation exists automatically once the statutory trigger is met. However, the statutory duty to provide particulars arises where a person with reasonable grounds requires them. Where nobody is present to request details, the driver must still stop, and should take reasonable steps to ensure their details can be provided, including reporting the accident where required.
A driver who fails to stop commits the offence even if they later report the matter within 24 hours. Reporting is a separate duty and does not retrospectively remove liability for failing to stop.
2. The Duty to Provide Details
If required by a person with reasonable grounds for asking, the driver must provide the following particulars:
- their name and address
- the name and address of the vehicle’s owner, if different
- the vehicle’s registration mark
A person with reasonable grounds may include the other driver, a pedestrian involved, the owner of damaged property or a police officer.
The duty is to provide accurate details. Providing false information, incomplete details or deliberately misleading particulars may constitute a separate offence and will almost certainly be treated as an aggravating factor on sentence.
It is not enough to simply remain silent at the scene. The statutory requirement is active: details must be given if requested.
3. The Duty to Report the Accident
If, for any reason, the driver does not give their name and address at the scene to a person having reasonable grounds to require them, the accident must be reported.
The report must be made in person at a police station, or to a constable, as soon as reasonably practicable and in any event within 24 hours of the accident.
Telephoning the police may not satisfy the statutory requirement unless a constable takes the report and the circumstances clearly meet the statutory test. The safest course is to report in person at a police station if the required particulars were not exchanged at the scene.
Failure to report within 24 hours constitutes a separate offence under section 170. A driver may therefore face charges for both failing to stop and failing to report.
It is no defence that the driver intended to report the matter later but failed to do so within the statutory timeframe.
4. Producing Insurance Documents
An additional requirement applies where personal injury is caused to someone other than the driver. This duty arises only where personal injury has been caused.
If the driver does not produce a certificate of insurance at the time of the accident to a constable, or to any person having reasonable grounds to require it, they must report the accident to the police and produce a valid insurance certificate as soon as reasonably practicable, and within seven days of the accident.
This requirement is separate from the 24-hour reporting duty. It is possible to comply with one obligation but fail to comply with the other.
In practice, drivers who are uninsured may face additional charges under section 143 RTA 1988 for using a motor vehicle without insurance.
Section B Summary
After an accident falling within section 170 RTA 1988, a driver must stop, provide accurate details if required and, where necessary, report the matter to the police within 24 hours. If personal injury is involved and insurance cannot be produced at the scene when required, the driver must produce it within seven days. Failing to stop after an accident is therefore not a single obligation but part of a broader statutory framework. Non-compliance with any element can result in prosecution, penalty points and potential disqualification.
Section C: Penalties for Failing to Stop After an Accident
Failing to stop after an accident is a criminal offence prosecuted in the Magistrates’ Court. The penalties are not symbolic. Parliament has provided for imprisonment, an unlimited fine and endorsement of penalty points or disqualification. The seriousness of the sentence depends on culpability, harm and the offender’s record.
The court will sentence in accordance with the Sentencing Council guideline for fail to stop and fail to report offences. Although many incidents involve minor damage, the offence is treated seriously because leaving the scene can obstruct investigation, delay medical assistance and frustrate civil claims.
1. Maximum Sentence
The statutory maximum penalty for failing to stop after an accident is:
- an unlimited fine
- up to 26 weeks’ imprisonment
The same maximum applies to the related offence of failing to report.
Custody is reserved for more serious cases, particularly those involving injury, deliberate evasion or aggravating features, but it remains available to the court in appropriate circumstances.
2. Penalty Points and Disqualification
In addition to, or instead of, a fine or custodial sentence, the court must endorse the driver’s licence with between 5 and 10 penalty points unless it imposes a discretionary disqualification.
The length of any disqualification will depend on the seriousness of the case. In higher culpability cases, especially where injury is involved or there was an attempt to evade drink or drug testing, the court may impose a substantial period of disqualification.
A motorist who accumulates 12 or more penalty points within a three-year period faces disqualification under the “totting up” procedure. This normally results in a minimum six-month driving ban unless exceptional hardship can be established.
For drivers who already have existing points on their licence, a conviction for failing to stop after an accident can therefore trigger a mandatory disqualification even where the incident itself was relatively minor.
3. Sentencing Guidelines
The Sentencing Council guideline adopts a structured two-stage approach.
Stage 1 – Determine offence category
The court assesses culpability and harm.
Stage 2 – Determine starting point and range
The court identifies the appropriate sentencing range before adjusting for aggravating and mitigating factors, a guilty plea and totality where applicable.
There are three offence categories.
Category 1 – Higher culpability and greater harm
Examples include leaving the scene to avoid being tested for drink or drug driving, knowing or suspecting that serious injury had been caused, leaving an injured person without assistance or giving false details.
The starting point is a high-level community order. The sentencing range extends from a low-level community order up to 26 weeks’ custody. The court may impose 6–12 months’ disqualification or 9–10 penalty points.
Category 2 – Mixed culpability and harm
This category includes higher culpability with lesser harm, or lower culpability with greater harm.
The starting point is a Band C fine. The range extends from a Band B fine to a medium-level community order. The court may impose up to 6 months’ disqualification or 7–8 penalty points.
Category 3 – Lower culpability and lesser harm
This typically involves minor damage and no deliberate attempt to evade detection.
The starting point is a Band B fine. The range extends from a Band A fine to a Band C fine, together with 5–6 penalty points.
4. Aggravating and Mitigating Factors
After identifying the appropriate category and starting point, the court considers factors that may increase or reduce the sentence.
Aggravating factors
- previous convictions, especially for similar offences
- committing the offence while on bail or licence
- evidence of bad driving
- little or no attempt to comply with statutory duties
- attempting to conceal identity or providing false details
Providing false details or deliberately leaving the scene to avoid arrest for another offence will significantly increase seriousness.
Mitigating factors
- genuine remorse
- a genuine belief that details had been exchanged
- genuine fear of retribution
- previous good character
- serious medical conditions requiring urgent or long-term treatment
- being the sole or primary carer for a dependent
Mitigation does not excuse the offence but may reduce the severity of the penalty.
Section C Summary
Failing to stop after an accident can result in an unlimited fine, up to 26 weeks’ imprisonment and 5–10 penalty points or discretionary disqualification. Sentencing depends on culpability and harm, with deliberate evasion and injury placing an offender at serious risk of custody and a substantial driving ban. Even in less serious cases, penalty points can lead to disqualification under the totting-up rules.
Section D: Defences and Prosecution Time Limits
Although failing to stop after an accident is a strict statutory duty, conviction is not automatic. The prosecution must prove each element of the offence beyond reasonable doubt. Where one element is not established, the defendant is entitled to be acquitted.
In practical terms, the prosecution must prove that:
- an accident occurred owing to the presence of a mechanically propelled vehicle
- the accident occurred on a road or other public place
- the accident caused injury or qualifying damage within section 170
- the defendant was the driver
- the defendant knew, or there was at least a real possibility that they knew, that an accident involving injury or damage had occurred
- the defendant failed to comply with the duty to stop or report
If any one of these elements cannot be proved, the offence is not made out.
1. Lack of Knowledge
One of the most common defences to failing to stop after an accident is lack of knowledge.
A driver cannot be convicted unless the court is satisfied that they knew, or that there was at least a real possibility that they knew, that an accident involving injury or damage had occurred. The test is objective as well as subjective. The court may consider whether a reasonable driver in the same position would have realised that an accident had taken place.
Knowledge may be inferred from circumstances, including:
- the force of impact
- the noise or vibration caused
- visible damage to the defendant’s vehicle
- CCTV or witness evidence
If the circumstances were such that a reasonable driver would have realised there was at least a real possibility of injury or damage, the court may conclude that the defendant ought to have known.
This defence most commonly arises in low-speed manoeuvring incidents, such as minor contact in car parks, where the driver asserts that they were genuinely unaware of any collision.
2. Belief That Details Were Provided
Another issue arises where a driver believes that their identity was known or that details had effectively been exchanged.
Examples may include situations where drivers know each other personally, where police attended immediately, or where some information was provided but not formally recorded.
A genuine and reasonable belief that the statutory requirement had been satisfied may be relevant. However, this is highly fact-specific. The duty under section 170 is clear. The safest course is always to provide full and accurate particulars in a clear and unequivocal manner.
Mere assumption that “they know who I am” may not be sufficient to avoid liability.
3. Procedural and Evidential Issues
As with all criminal offences, the prosecution bears the burden of proof.
Defences may arise where:
- the identity of the driver cannot be established
- the accident location does not qualify as a road or public place
- there is insufficient evidence that injury or qualifying damage occurred
Disputes frequently arise in cases involving alleged non-contact collisions, minor vehicle contact or conflicting witness accounts. Where the evidence is unclear, the court must give the defendant the benefit of the doubt.
4. Time Limit for Prosecution
Failing to stop and failing to report are summary-only offences. They are dealt with in the Magistrates’ Court.
Proceedings must be commenced within six months of the date of the offence. In practice, this means that the prosecution must lay an information before the court within that six-month period, in accordance with section 127 of the Magistrates’ Courts Act 1980.
If proceedings are not commenced within that timeframe, the court has no jurisdiction to try the offence.
Where failing to stop is charged alongside more serious indictable offences, such as dangerous driving, the procedural framework may differ. Early legal advice should be sought where prosecution is anticipated.
Section D Summary
A conviction for failing to stop after an accident requires proof that the statutory elements are satisfied, including knowledge that an accident involving injury or damage had occurred. Lack of knowledge, evidential weakness and procedural defects may provide a defence. As summary-only offences, failing to stop and failing to report must normally be prosecuted within six months.
FAQs
Failing to stop after an accident is widely misunderstood. The following answers address common questions raised by motorists facing investigation or prosecution.
Is failing to stop after an accident a criminal offence?
Yes. Failing to stop after an accident is a criminal offence under section 170 of the Road Traffic Act 1988. It is prosecuted in the Magistrates’ Court and can result in penalty points, disqualification, a fine or imprisonment.
It is not merely a civil matter linked to insurance. It is a criminal offence even where the underlying accident was minor and even where the driver was not at fault.
Is failing to stop the same as “hit and run”?
“Hit and run” is a media expression, not a formal legal term. The offence in law is failing to stop and, where applicable, failing to report under section 170 RTA 1988.
In practice, what the public describes as a hit and run is usually prosecuted as failing to stop after an accident, sometimes together with failing to report.
How many points do you get for failing to stop?
The court must endorse the driver’s licence with between 5 and 10 penalty points unless it imposes a discretionary disqualification.
The exact number depends on the seriousness of the case, including culpability and harm. Drivers who already have points may face disqualification under the totting-up procedure if the total reaches 12 points within three years.
Can you go to prison for failing to stop after an accident?
Yes. The maximum penalty is 26 weeks’ imprisonment and an unlimited fine.
Custodial sentences are more likely where the offender deliberately left to avoid drink or drug testing, serious injury was caused, false details were provided or there is a poor driving record. While many cases result in fines and points, custody remains available in serious cases.
What if I did not realise I had hit another vehicle?
A driver cannot be convicted unless the prosecution proves that they knew, or that there was at least a real possibility that they knew, that an accident involving injury or damage had occurred.
Where the impact was minor and genuinely unnoticed, this may provide a defence. However, the court can infer knowledge from circumstances such as the force of impact, noise, visible damage or other evidence.
Each case turns on its own facts.
Does failing to stop always lead to a driving ban?
Not necessarily. The court has discretion to impose either penalty points or disqualification.
In lower category cases, penalty points are more common. In higher culpability cases, especially those involving injury or evasion, disqualification is more likely. Where a driver reaches 12 points under the totting-up rules, disqualification may follow even if the court did not initially impose a direct ban.
Conclusion
Failing to stop after an accident is a serious criminal offence under section 170 of the Road Traffic Act 1988. The duty arises automatically where injury or qualifying damage occurs on a road or public place. It applies regardless of fault and even where damage is minor.
A driver must stop, provide accurate details if required and report the accident within 24 hours if those details are not exchanged. Where personal injury is involved and insurance cannot be produced at the scene when required, it must be produced within seven days.
The penalties can include an unlimited fine, up to 26 weeks’ imprisonment, 5 to 10 penalty points or discretionary disqualification. Sentencing depends on culpability and harm, with deliberate evasion and injury significantly increasing seriousness.
Motorists should never assume that leaving the scene is a minor matter. Even a low-speed car park incident can result in criminal prosecution. The safest course is always to stop, exchange full details clearly and report the matter where required.
