We examined the physical, visual, health, and cognitive abilities of 1,656 older adults as prospective predictors of self-reported driving cessation over a 5-year period. We examined the time to driving cessation across 5 years after we controlled for days driven per week at baseline and any cognitive intervention participation. Older age, congestive heart failure, and poorer physical performance (according to the Turn 360 Test) were statistically significant risk factors for driving cessation. Slower speed of processing (according to the Digit Symbol Substitution and Useful Field of View tests) was a significant risk factor even after we took baseline driving, age, health, vision, and physical performance into consideration. Implications are that assessments of cognitive speed of processing can provide valuable information about the subsequent risk of driving cessation.

Key Words: Driving cessation • Speed of processing • Cognition • Older driver • Vision
