Illegal Drugs (Driving)

Volume 449: debated on Monday 24 July 2006

To ask the Secretary of State for Transport how many motorists killed in road accidents in each of the last five years had traces of illegal drugs in their bodies. (87485)

This information is not available. A study of fatal accident victims during the period 1996-2000 showed that in a sample of 779 drivers and riders killed, 17 per cent. had traces of illegal drugs. In 8 per cent. of the sample the drug detected was cannabis, traces of which remain detectable in the body long after consumption.

To ask the Secretary of State for Transport what estimate he has made of the number of motorists who drove with illegal drugs in their bodies in the last 12 months. (87486)

No such estimate is made by the Department. A 2004 European Commission study “Impaired motorists: methods of roadside testing and assessment for licensing” co-funded by member states, examined the prevalence of illegal drugs in drivers. The summary of the results of the UK element of that study are at 5194. The full report is at
