The Effect of Age on Decision Making During Unprotected Turns Across Oncoming Traffic

---

Abstract

The present study examined whether age-related differences in quantitative measures of left-tum 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. Significant effects of age were found in decision time, turn time and gap size. A significant interaction between age group and the speed of oncoming traffic was obtained for decision time. Implications for older adult's safety and future directions are discussed.
