Older drivers and road safety: the acceptability of a range of intervention measures.

A survey questionnaire was used to ascertain the views of 1932 UK drivers aged between 50 and 90 on a range of measures designed to promote safer driving among the elderly. Factor analysis of the items produced six factors, relating to statistically distinct types of measure. Differences in acceptability on the basis of age and sex were explored. Ratings of the effectiveness of each measure revealed little consensus about which measures would be most effective. Compulsory re-testing after a driving ban, a police power to require an assessment of the driving of anyone observed driving in a risky manner, and a requirement for opticians to report to the licensing authority any driver with sight problems likely to affect driving emerged as the individual measures offering the best combination of acceptability and perceived effectiveness.
