Age, health and driving : longitudinally observed changes in reported general health, in mileage, self-rated competence and in attitudes of older drivers.

An older driver's questionnaire was administered in 1994-5 to 1780 drivers 54 to 99 years of age and a follow up questionnaire in 1996 to 395 drivers remaining from this group. Ages, socioeconomic status and location were very similar for the two samples. While the variation between individuals was considerable, estimates of weekly driving declined with age. Reduction in mileage with time was predicted by health status/decline in health status, and by decline in confidence in driving competence. The same factors indicated increasing use of public transport and transport provided by friends and relatives. Attitudes to other road users and to possible restrictions did not change with time. Most respondents reported that they valued their independence and would have difficulties if they had to give up their cars, especially if they cared for spouses with limited mobility.
