Dr. Tony WrightTo ask the Secretary of State for the Environment, Transport and the Regions what estimate he has made of the number of road accidents caused by drivers falling asleep. [75266]
§ Ms Glenda JacksonThere is no national estimate of the number of accidents caused by drivers falling asleep. However, research has shown that tiredness is a principal factor in around 10 per cent. of all accidents. Accordingly, it is estimated that around 23,000–24,000 injury accidents a year result from driver fatigue.
