Summary

This study evaluates the efficacy of an integrated training program, SAFE-T, designed to minimize driver distraction by improving three critical cognitive skills: hazard anticipation (HA), hazard mitigation (HM), and attention maintenance (AM). While previous research established that novice drivers perform worse than experienced drivers in these areas, existing training programs typically targeted only one skill individually. The researchers sought to determine if SAFE-T, which had previously shown effectiveness in reducing fatigue-related performance deficits in experienced drivers, could similarly improve these skills in novice drivers. Additionally, the study compared the effect size of SAFE-T against RAPT, a program specifically designed for hazard anticipation, to assess whether the integrated approach maintained effectiveness despite reduced training exposure. The experimental design involved 48 students aged 16 to 18, all holding valid driver’s licenses. Participants were randomly assigned to one of three conditions: SAFE-T, RAPT, or a placebo control. Following their assigned training, participants completed a driving simulator evaluation consisting of a single "drive set" across four virtual environments (Town, Highway, Rural, and Residential). Each environment contained specific scenarios for HA, HM, and AM. HA and HM scenarios involved latent hazards requiring scanning and response, while AM scenarios required participants to perform in-vehicle tasks (such as searching for a CD or dialing a number) that necessitated glancing away from the roadway. The order of environments and tasks was counterbalanced to control for sequence effects. The results demonstrated that SAFE-T significantly improved performance across all three cognitive skills. In hazard anticipation, the SAFE-T group achieved a 26 percentage point gain in correctly anticipated hazards compared to the placebo group, a result statistically indistinguishable from the 25 percentage point gain observed in the RAPT group. For hazard mitigation, SAFE-T participants responded earlier and more rapidly than the placebo group in two scenarios. Crucially, SAFE-T successfully reduced the proportion of off-road glances exceeding two seconds, a duration known to elevate crash risk. This reduction was greater than that achieved by the RAPT group and comparable to the specialized FOCAL program, despite SAFE-T requiring only 15 minutes of training versus FOCAL’s 40 minutes. The RAPT group did not show improvements in attention maintenance, indicating a lack of generalization from hazard-focused training to attention skills. The findings suggest that integrated training programs like SAFE-T can effectively enhance multiple safety-critical skills in novice drivers within a significantly shorter timeframe than individualized programs. The study implies that training one cognitive skill may facilitate the improvement of others, potentially due to an optimal balance of exposure and exemplars that aids skill generalization. These results indicate that SAFE-T holds strong promise for improving young driver safety by efficiently addressing hazard anticipation, mitigation, and attention maintenance simultaneously.

Key finding

Compared with placebo, SAFE-T training improved novice drivers' hazard anticipation by 26 percentage points and cut the proportion of off-road glances longer than two seconds by 11.7 percentage points, despite requiring only 15 minutes of training.
