Abstract
The objective of this study was to determine whether older drivers with poorer cognitive and/or visual function drive fewer miles or avoid driving in situations that pose higher crash risks, such as at nighttime, in rush hour traffic, or when weather conditions are bad. A cross-sectional data analysis was conducted as part of a larger prospective study. The subjects were administered batteries of tests of cognitive and visual function; and they were also asked to complete a brief driving survey containing questions about the number of miles driven and whether they avoided driving under certain conditions, such as after dark or on busy, multi-lane highways. Driver age and gender were covariates in the analyses. (A)
