If you are under investigation following a fatal road collision, you could face prosecution for either of two offences: causing death by careless driving or causing death by dangerous driving. Both are serious motoring offences that can lead to custody, mandatory disqualification and lasting personal and professional consequences.

The key difference lies in the standard of driving – does the driving fall below, or far below that of a careful and competent driver? This minor detail leaves it open to an expert motoring lawyer to assess the facts of your case and seek to reduce the charge in various circumstances.

This distinction is ambiguous, but it significantly affects the charge and sentence, with causing death by dangerous driving carrying a maximum sentence of life imprisonment. As such, it is important to work with an experienced solicitor in these cases, as the outcome is not determined by the fatality alone. The evidence, level of culpability, aggravating and mitigating factors, and any guilty plea will all influence the final sentence.

Here, JMW’s motoring solicitors explain the difference between causing death by careless and dangerous driving, when a sentence may be reduced through mitigation and when it may be possible to challenge the charge entirely.

What Is ‘Causing Death by Careless Driving’?

Under section 2B of the Road Traffic Act 1988, causing death by careless or inconsiderate driving applies where a person causes another person’s death by driving without due care and attention or without reasonable consideration for other road users.

The prosecution must prove that:

• You were driving a mechanically propelled vehicle.
• Your driving fell below the standard expected of a competent and careful driver.
• Your driving caused or made a significant contribution to the death.

The offence does not require the prosecution to prove that you intended to drive carelessly or cause harm. It can arise from a lapse in concentration, an error of judgement or a failure to make the observations expected of a careful driver. This might include:

• Failing to see a pedestrian, cyclist or horse rider.
• Misjudging the speed or distance of another vehicle.
• Moving into an overtaking lane without making proper observations.
• Failing to respond correctly to traffic lights or road signs.
• Driving too closely behind another vehicle.
• Falling asleep at the wheel.
• Using a mobile phone or another device.

Not every example will automatically amount to causing death by careless driving. The prosecution must still prove that the driving fell below the required standard and that it caused the death. In these cases, JMW’s death by careless driving solicitors will assess the evidence against these legal requirements and identify how the case can be challenged.

What Is ‘Causing Death by Dangerous Driving’?

Causing death by dangerous driving is an offence under section 1 of the Road Traffic Act 1988. It applies where a person causes another person’s death by driving a mechanically propelled vehicle dangerously on a road or other public place.

For driving to be classed as dangerous:

• It must fall far below the standard expected of a competent and careful driver.
• It must have been obvious to a competent and careful driver that driving in that way would be dangerous.

Dangerous driving usually involve a clear and obvious risk of injury or serious damage to property. 

Examples include (but are not limited to): 

• Racing
• Aggressive driving
• Ignoring road signs or traffic lights
• Significant impairment through drink/ drugs
• Mobile phone us
• Driving a vehicle with a known dangerous fault.

The court assesses the incident as a whole. The duration of the driving, the level of danger created and the surrounding circumstances will all play a part in the nature of the charge against a person.

The prosecution must also prove causation. It is not enough to show that dangerous driving took place at some point before a fatal collision. The driving must be shown to have caused or made a significant contribution to the death.

Our dangerous driving solicitors examine the prosecution's case, to test whether it is sound. Where the circumstances and evidence supports it, we will challenge any suppositions with the goal of seeing the penalty mitigated, charges reduced and in some cases, dropped entirely.

How Do the Police Decide Which Offence to Investigate?

Following a fatal collision, the police will investigate the circumstances and gather evidence before the Crown Prosecution Service makes a charging decision. This could include:

• Statements from drivers, passengers and other witnesses.
• CCTV and dashcam footage.
• Mobile phone data.
• Vehicle examinations.
• Collision reconstruction reports.
• Evidence about speed, braking and road position.
• Toxicology evidence.
• Traffic-light sequences and road signs.
• Information about the driver’s sleep, medication or medical history.
• Answers given during a police interview.

The police may initially investigate whether the incident amounts to causing death by dangerous driving because it allows them to consider the most serious potential offence. This does not mean that the evidence will ultimately support that charge.

It is important to involve a specialist motoring solicitor as early as possible, and before any interview under caution. Early advice means you can understand the nature of the allegations and respond appropriately to police questions. Your solicitor will be able to review the evidence against you, and where appropriate instruct independent collision experts. This work will make sure the Crown Prosecution Service assesses the case on the full evidence rather than an incomplete account of what happened.

R v JB: Demonstrative of the importance of expert instruction from interview stage onwards, JMW were able to use their knowledge and expertise to mount a defence to a charge of death by dangerous driving. Whilst it was initially alleged that mobile phone use played a part in the collision, JMW’s detailed review and instruction of appropriate experts resulted in acquittal at trial of the substantive charge.

Can a Dangerous Driving Allegation Be Reduced to Careless Driving?

Depending on the evidence, your solicitor may be able to show that the driving amounted to a brief lapse or isolated misjudgement rather than sustained dangerous conduct, which would potentially reduce a charge of dangerous driving to careless driving. To support this, we may challenge accounts of the speed or risk involved, or test whether footage, witness evidence or expert analysis supports the prosecution’s case to identify any inconsistencies.

The actions of other road users, road and weather conditions, mechanical issues and the circumstances leading up to the collision may also be relevant. Ultimately, the prosecution must prove both that the driving crossed the higher dangerous driving threshold and that it caused the death. Where that has not happened, a charge can be reduced.

R v IG: JMW were able to substantiate the assertion that the matter was one of causing death by careless driving, not dangerous driving through the meticulous review of the papers and the instruction of a forensic collision expert. Demonstrative of the importance of instructing the right expert from the outset, JMW were able to achieve a suspended sentence for the lesser charge: Death by Careless Driving – Custodial Sentence Avoided - JMW

What Are the Penalties for Death by Careless Driving?

Causing death by careless or inconsiderate driving carries a maximum sentence of five years’ custody. Under the current sentencing guidelines, penalties range from a community order to four years’ custody.

The sentence depends on the level of culpability. If a driver is convicted of causing death by careless driving, the penalties can include:

• A prison sentence of up to five years
• An unlimited fine
• A mandatory driving disqualification for a minimum of 12 months

The court considers how far the driving fell below the required standard and whether the case involved aggravating factors like:

• Driving while tired or distracted.
• Using a mobile phone.
• Driving at an inappropriate speed.
• Ignoring warnings.
• Carrying out another activity while driving.
• Driving with a known medical condition that affected safety.

Aggravating factors: Previous convictions, driving whilst disqualified, driving whilst unlicensed or uninsured, leaving the scene and causing additional injuries will also increase the sentence.

Mitigating factors: a previously good driving record, genuine remorse, cooperation with the police, assistance at the scene, age and lack of maturity, and relevant personal circumstances can reduce the severity of your penalty. 

An early guilty plea could also reduce the custodial sentence, although it does not remove the mandatory driving disqualification.

Your solicitor will advise on whether the evidence can be challenged or whether a guilty plea with detailed mitigation will deliver the best outcome for you. We also gather the documents needed to present the defendant’s circumstances fully, including medical evidence, references and information about the impact of an immediate custodial sentence on other people.

What Are the Penalties for Death by Dangerous Driving?

Causing death by dangerous driving carries a maximum sentence of life imprisonment for offences committed after 28 June 2022. The current sentencing range for a single offence is between two and 18 years’ custody.

The sentencing judge begins by assessing the offender’s culpability. The most serious cases involve prolonged and deliberate dangerous driving, grossly excessive speed, racing, evading the police or driving while highly impaired by drink or drugs.

Cases at the lower end of the guideline may involve driving that only just crosses the threshold from careless to dangerous. However, a custodial sentence remains likely because the offence has caused a death - learn more in our blog post on suspended sentences in death by dangerous driving cases.

A conviction also carries:

• A mandatory driving disqualification.
• A compulsory extended driving retest.
• The possibility of an unlimited fine.

For relevant offences committed after 28 June 2022, the minimum disqualification is five years. The court will extend the ban to account for time spent in custody.

A conviction also carries a mandatory driving disqualification of at least 5 years, and an order preventing the driver from regaining a full licence until they pass an extended driving test. Once the minimum disqualification period has expired, they must normally apply for a provisional licence and pass the relevant theory and extended practical tests before they can drive unsupervised again. 

Given the difference between the available sentences, it is essential to have your solicitor scrutinise whether the evidence supports dangerous driving or the lesser careless-driving offence.

What Happens After a Fatal Road Collision?

Following a road traffic accident, the process will usually unfold as follows:

1. Police attendance: The police usually begin gathering evidence immediately. They may close the road, photograph the scene, examine the vehicles involved and obtain statements from witnesses.
2. Arrest and interview: You may be arrested at the scene or asked to attend a voluntary police interview later. A voluntary interview is conducted under caution and anything you say may be used as evidence.

You have the right to legal advice during a police interview. It is imperative that you speak to a specialist motoring solicitor before answering questions. Ideally, you should instruct the solicitor at the interview stage, who you would wish to represent you if you were charged. You should not be swayed towards non-expert advice just because it is ‘only’ the interview. 

An expert will allow you to understand the allegation, the evidence disclosed by the police and the possible consequences of your account. This can have significant implications later down the line, particularly if you later wish to argue for a lesser charge (careless driving), or preserve maximum credit for a guilty plea. 

JMW can attend a police interview with you and offer legal representation to protect your position.

1. Post-investigation: After the investigation, the police submit the evidence to the Crown Prosecution Service. The prosecutor then decides:

• Whether there is sufficient evidence for a realistic prospect of conviction.
• Which offence the evidence supports.
• Whether a prosecution is in the public interest.

1. Charging decision: If you are charged, the case will begin in the Magistrates’ Court. A death by careless driving charge may remain there or be sent to the Crown Court, while a death by dangerous driving charge must proceed to the Crown Court.
2. Case preparations and decision as to plea: Immediately following charge you will begin case preparation and where necessary, the engagement of relevant experts to produce supporting evidence. You will meet with your solicitor and receive advice before entering a guilty or not-guilty plea. 

As soon as possible after your arrest, you should seek the support of our specialist motoring solicitors. We will assess whether the charge is appropriate and ensure that you do not enter a plea before fully understanding your legal position.

How Can JMW Help?

A solicitor’s role begins well before the trial or sentencing hearing. Early legal advice will affect how you approach the police investigation and how the evidence is interpreted.

We can:

• Advise and represent you during a police interview.
• Establish which offences the police are considering.
• Review the evidence disclosed by the police.
• Preserve CCTV, dashcam and other time-sensitive evidence.
• Analyse mobile phone and vehicle data.
• Examine police collision reports.
• Instruct independent vehicle, medical or collision reconstruction experts.
• Identify weaknesses or inconsistencies in witness accounts.
• Assess whether the prosecution can prove causation.
• Challenge whether the driving meets the dangerous-driving threshold.
• Make representations that careless driving is the appropriate charge.
• Advise you on whether to plead guilty or not guilty.
• Prepare detailed mitigation and supporting evidence.
• Represent you in the Magistrates’ Court and Crown Court.
• Advise you on disqualification and any compulsory retest.

Fatal collisions often turn on small but significant factual details, such as the time available to react, the visibility at the scene or the precise sequence of events. We examine these matters carefully rather than accepting the initial characterisation of the driving.

Where a defence is available, we prepare the case and challenge the prosecution evidence. Where the evidence supports a guilty plea, we ensure that the court understands the circumstances, your personal position and all possible factors that can reduce the sentence.
