Effect of passenger presence on older drivers' risk of fatal crash involvement.

Objective: To determine the association between passenger presence and risk of fatal crash involvement in relation to driver and passenger age and gender, focusing especially on drivers ages 65 and older.

Methods: Data on US fatal crashes were obtained for 2002-2009. Using the quasi-induced exposure methodology, logistic regression analysis was used to predict the odds of fatal crash involvement as a function of driver age and gender as well as passenger age and gender.

Surveys assessed driving behavior, crashes, and violations as well as self-reported visual impairments, prescription medications, and physical mobility limitations.
