Abstract

The present study examined whether age-related differences in quantative measures of left-turn performance could explain older drivers' increased susceptibility to crashing while making unprotected left turns across traffic. Older and younger adults made left turns across traffic in a driving simulator. Time to decide to turn, time to negotiate the turn, the size of the accepted gap, gap clearance, and time to collision with an oncoming vehicle were measured. A significant interaction between age group and the speed of oncoming traffic as obtained for decision time. Implications for older adults' safety and future directions are discussed.
