DRIVING STANDARD • CAUSATION • COLLISION • EXPERT EVIDENCE

Dangerous Driving & Causing Death by Dangerous Driving

Dangerous-driving cases turn on an objective assessment of the standard of driving. Fatal cases add causation. CCTV, dashcam, vehicle data, road layout, visibility and expert reconstruction can be decisive.

KEY ANSWER

The position in brief

Dangerous driving is assessed by the statutory test in the Road Traffic Act 1988: whether the driving fell far below the standard expected of a competent and careful driver and whether it would be obvious to such a driver that driving in that way would be dangerous.

Where death is alleged, the prosecution must additionally prove the dangerous driving caused the death.

Legal issues

The distinction between careless and dangerous driving is central. Speed alone, distraction, manoeuvres, vehicle condition, fatigue and road conditions must be analysed against the statutory test rather than labelled in isolation.

Evidence that matters

Evidence may include CCTV/dashcam, collision reconstruction, vehicle event data, telematics, mobile-phone evidence, road measurements, weather/visibility, toxicology, witness accounts and mechanical examination.

Reasonable lines of enquiry

Enquiries may include independent reconstruction, full route footage, phone use records, vehicle defects, road signage/lighting, stopping distances and whether another event materially affected causation.

What happens next

Serious and fatal driving cases may proceed to the Crown Court and commonly involve expert evidence. CPS guidance distinguishes dangerous from careless driving by the statutory standard, not simply by outcome severity.

Immediate steps

Preserve dashcam, telematics and phone data. Record route, weather and visibility while fresh. Identify witnesses and nearby CCTV quickly.

What should you send us?

FREQUENTLY ASKED QUESTIONS

Questions about this issue

What makes driving dangerous rather than careless?

Dangerous driving requires driving falling far below the competent-and-careful standard, with the danger obvious to such a driver. Careless driving applies a lower statutory threshold.

Can expert reconstruction be challenged?

Yes. Assumptions, measurements, speeds, timing and causation can all be examined and, where justified, independently reviewed.

Does a fatal outcome automatically mean dangerous driving?

No. The prosecution must prove the dangerous-driving standard and causation. The seriousness of the outcome does not replace the statutory test.
