  1. For this analysis designed to provide normative values for healthy older adults, we excluded measures from patients with health conditions that might have affected their performance. Therefore, normative data is provided for older drivers with normal optical vision, no cognitive impairment (MoCA ≥ 26), normal functional mobility (TUG < 13.5 sec), no known risk of sudden blackout, and without class III medication affecting driving performance. TMT = trail making task, SD = standard deviation.
