The longer-term effects of a brief hazard perception training intervention in older drivers.

Previous research has shown that drivers aged over 65 years can improve their scores in video-based hazard perception tests following training interventions. In order to examine the longer-term effects of hazard perception training, we recruited 75 drivers aged 65 and over. They either received a 35-min hazard perception training intervention or a placebo intervention. Significant decreases in hazard perception response time as a result of the training were found immediately after the intervention, and approximately 1 month and 3 months later. There was no significant decay in the training effect over this time period.
