Introduction
Being charged with causing death by dangerous driving is one of the most serious motoring offences in England and Wales. If a fatal road traffic collision occurs and the prosecution alleges that the driving was dangerous, the case will be dealt with in the Crown Court and can lead to severe penalties.
Understanding the law, the potential consequences and the possible defence issues is important if you are facing this allegation.
What Is Causing Death by Dangerous Driving?
The offence of causing death by dangerous driving is created by section 1 of the Road Traffic Act 1988.
It applies where a person drives a mechanically propelled vehicle dangerously on a road or public place, and that driving causes the death of another person.
The offence deals with fatal road collisions where the standard of driving is alleged to have fallen far below what would be expected of a competent and careful driver.
Legal Definition of Dangerous Driving
A person is considered to be driving dangerously if:
- Their driving falls far below the standard expected of a competent and careful driver, and
- It would be obvious to a competent driver that the manner of driving was dangerous.
Danger in this context includes a risk of injury to others or serious damage to property.
Examples that may amount to dangerous driving include:
- Excessive speeding
- Racing or aggressive driving
- Ignoring traffic signals
- Driving while distracted
- Driving while impaired by alcohol or drugs
Every case depends on its specific circumstances.

What Must the Prosecution Prove?
To secure a conviction for causing death by dangerous driving, the prosecution must establish two key elements.
1. Dangerous Driving
First, it must be proved that the defendant was driving in a way that fell far below the standard expected of a competent and careful driver.
This assessment is objective and considers factors such as:
- Speed
- Road conditions
- Traffic conditions
- Visibility
- The behaviour of the driver
2. The Driving Caused the Death
Secondly, the prosecution must show that the dangerous driving caused the fatality.
This means the driving must be a significant cause of the death. If another factor caused or contributed to the fatality, this may become a key issue in the case.
Accident reconstruction experts are often used in these cases to analyse:
- Vehicle speed
- Braking distances
- Collision dynamics
- Road conditions
These technical issues can play a major role in determining liability.
Sentences for Causing Death by Dangerous Driving
Causing death by dangerous driving carries extremely serious penalties.
Maximum Sentence
The maximum sentence for the offence is life imprisonment.
This reflects the gravity of the offence and the consequences for victims and their families.
Sentencing Factors
When determining the sentence, the court will consider a range of factors, including:
- The level of driving culpability
- The speed involved
- Whether alcohol or drugs were involved
- Previous driving convictions
- Attempts to avoid responsibility
- The overall circumstances of the collision
Aggravating features can significantly increase the sentence imposed.
Driving Disqualification
A conviction will normally result in:
- A mandatory driving disqualification
- A requirement to pass an extended driving test before driving again
The minimum period of disqualification following conviction is typically several years.
Possible Defences to Causing Death by Dangerous Driving
Although the allegation is serious, it may still be possible to challenge the prosecution case.
The appropriate defence will depend on the specific facts of the case.
Disputing Dangerous Driving
In some cases, the defence may argue that the driving did not fall far below the expected standard.
For example:
- The driver reacted reasonably in difficult circumstances
- Road or weather conditions contributed to the incident
- Another driver was responsible for the collision
Expert evidence may be used to support this argument.
Challenging Causation
Even if the driving is criticised, the prosecution must prove that it caused the death.
In some cases:
- Another driver may have been responsible
- Mechanical failure may have contributed
- The fatal outcome may not have been avoidable
Causation is often one of the most complex issues in fatal driving cases.
Evidential Challenges
The defence may also examine the reliability of the evidence.
Potential issues may include:
- Inaccurate accident reconstruction
- Unreliable witness evidence
- Incorrect assumptions about vehicle speed
- Failures in the police investigation
A detailed review of the prosecution evidence is essential.
