Abstract/Summary Hazard perception and speed choice are two of the strongest predictors of on-road accident involvement. Driving experience is positively associated with both hazard perception ability and speed limit compliance. Research has primarily focused on hazard perception and speed choice in isolation, but it is plausible that these driving facets are related. Specifically, it is possible that drivers‟ hazard perception skill predicts the extent to which they moderate their speed preferences in response to potential traffic hazards. To test this proposal, young novice drivers (a group with poor hazard perception ability) and older experienced drivers (a group with better hazard perception ability) completed three video-based driving tasks. First, explicit speed preferences were measured using a video speed test involving embedded hazards. Second, implicit speed preferences were measured using an Implicit Association Test (IAT) with embedded hazards. Finally, a validated hazard perception test was used to evaluate how quickly participants detected potential hazards independent of speeding propensity. It was hypothesized that greater hazard perception ability (either as directly measured via the hazard perception test or manipulated via driver group) would result in both an explicit and implicit preference for slower speeds when more hazardous scenarios were encountered. Support for this hypothesis was varied. Older experienced drivers were found to have both an explicit and implicit preference for slower speeds, consistent with previous research. However, this did not differ regardless of the scene type. In addition, scores on the hazard perception test did not differ between the two driver groups. The results are discussed in relation to previous research, current study limitations, implications of the findings, and directions for future research.
