HC Deb 21 February 1972 vol 831 c223W
Sir R. Russell

asked the Secretary of State for the Environment if he will list the age groups of drivers of motor vehicles in the order in which they are most prone to involvement in fatal and serious accidents.

Mr. Eldon Griffiths

As driving circumstances vary according to the age of the driver, accident rates for different age groups are not strictly comparable. However, a study by the Transport and Road Research Laboratory indicated that among car drivers the under-20 age group had substantially the highest accident involvement rate per mile driven. Other age groups in order of involvement rates were 20–24, 70 and over, 25–29, 30–39, 40–49, 50–69.
