Driving risk assessment of older drivers with reduced visual acuity.

This study examined the traffic violation conviction record of 87 Arizona- licensed older drivers who were reviewed by the Motor Vehicle Division's medical program and restricted to daytime driving only because of reduced visual acuity. Females alone accounted for the significant differences between the two groups, suggesting that they are at higher risk for hazardous driving then their male counterparts. Results are discussed in the context of overall driving practices of older persons and of the existing cohort of older females.
