The critical value was set at 0.05. There were 453 at-fault and 502 not at-fault participants.1 Bivariate analyses showed that drivers who have slept less than six hours in the past 24 hours, used psychotropic medication, and/or had consumed alcohol have a higher probability of being at-fault for a crash occurring at night (p = <0.0001). Outside and in-vehicle events, as well as activities associated with an increased likelihood of crashing, were strongly correlated with increased chances of being at-fault in a crash (p-value = 0.021, 0.0007, and 0.0001, respectively).1 These three factors accounted for 8% of all vehicle collisions. Listening to music or the radio, cell phone use, interacting with passengers, and navigation use did not result in a significant increase in at-fault collisions.
