Abstract
Hazard perception in driving is the one of the few driving-specific skills associated with crash involvement. However, this relationship has only been examined in studies where the majority of individuals were younger than 65. We present the first data revealing an association between hazard perception and self-reported crash involvement in drivers aged 65 and over. In a sample of 271 drivers, we found that individuals whose mean response time to traffic hazards was slower than 6.68 s [the receiver operating characteristic (ROC) curve derived pass mark for the test] were 2.32 times [95% confidence interval (CI), 1.46, 3.22) more likely to have been involved in a self-reported crash within the previous 5 years than those with faster response times. This likelihood ratio became 2.37 (95% CI, 1.49, 3.28) when driving exposure was controlled for. As a comparison, individuals who failed a test of useful field of view were 2.70 (95% CI, 1.44, 4.44) times more likely to crash than those who passed. The hazard perception test and the useful field of view measure accounted for separate variance in crash involvement. These findings indicate that hazard perception testing and training could be potentially useful for road safety interventions for this age group. (JINS, 2010, 16, 939-944.)
