Effect of video based road commentary training on the hazard perception skills of teenage novice drivers

Abstract

Recent evidence in the road safety research literature indicates that skills in hazard perception, visual search and attention may be developing executive functions in young novice drivers before the age of 25 years, contributing to their unintentional risk taking behaviour and subsequent high crash rates. The present research aimed to investigate these skills, whether they are predictive of each other, and whether hazard perception can be improved through road commentary training. Twenty-two young novice drivers and eight experienced drivers were recruited as participants in this study. The experienced drivers performed significantly better than the novice drivers on the hazard detection task that was specifically designed for the study. Their visual search skills were also examined and compared using the Visual Search and Attention Test, with the experienced drivers performing significantly better than the novice drivers. Interestingly, a significant positive correlation was found between the scores of the participants on the hazard detection task and the Visual Search and Attention Test which may indicate that the hazard detection skills can be predicted. The novice driver group who received 12 trials of video based road commentary training significantly improved in their hazard detection skills, suggesting that video based road commentary could be an effective road safety intervention for young novice drivers and if developed into a more comprehensive programme, holds promise for future implementation into the New Zealand Graduated Driver Licensing System. The results also hold promise for future investigation into the use of the Visual Search and Attention Test as a predictor of hazard perception skills in novice drivers.
