§ Mr. Peter Bottomley
To ask the Secretary of State for Transport, pursuant to his answer of 2 FebruaryOfficial Report, column 117, on injury crashes, if he will express the estimates as incidence rates.
§ Mr. Kenneth Carlisle
Comparable injury accident rates for drivers aged 17, 18 and 19 in relation to the number of full and provisional car driving licence holders in 1991 within these age groups, are available only for Northern Ireland and Great Britain and are shown in the table:
(Per 100 driving licence holders within each age group)
Accident Rates: Full and Provisional Licence Holders
Age Northern Ireland Great Britain 17 1.3 2.7 18 1.9 2.8 19 1.9 2.3 Total (17 to 19) 1.8 2.6
It would have been preferable to calculate rates in relation to mileage, which is a better measure of exposure to risk than numbers of licence holders, but this information is not available.
