Drugs found in road deaths: what the official data shows

The Department for Transport has published an analysis of coroner data looking at drugs found in the bodies of motor vehicle drivers and riders who were killed in reported road collisions, with figures now covering up to 2024.

The research focuses specifically on what substances were present at the time of fatal crashes, drawing on post-mortem toxicology results gathered through the coroner process. This kind of data gives a broader picture than roadside drug tests alone, because it covers everyone killed rather than only those stopped or suspected before a collision occurred.

For everyday drivers, the findings serve as a reminder that drug driving, whether involving illegal substances or certain prescription medicines, carries serious risks on public roads. The Department for Transport has consistently highlighted drug driving as a significant road safety concern alongside drink driving, and the law treats both with equal seriousness. Drivers can be prosecuted for being impaired by any substance, including legal medications that affect their ability to drive safely.

If you are unsure whether a prescribed medicine affects your driving, the best step is to check with your GP or pharmacist before getting behind the wheel. Some common medicines, including certain antihistamines, sleeping tablets and painkillers, can slow reactions or cause drowsiness. Being honest with yourself about your condition before driving is not just a legal matter but a practical one that affects everyone sharing the road.
