Hazard perception and driving experience among novice drivers

Area of Science:

• Road safety
• Driver behavior
• Cognitive psychology

Background:

• Novice drivers exhibit a rapid decrease in crash risk within months of licensing.
• This decline suggests the acquisition of crucial safety-relevant traffic skills.
• The role of hazard perception in this skill acquisition remains unclear.

Purpose of the Study:

• To investigate the hypothesis that improved hazard perception skills contribute to the reduced crash risk in novice drivers.
• To assess the impact of driving experience on hazard perception abilities.
• To examine the effect of increased mental load on hazard perception.

Main Methods:

• A video-based hazard perception and reaction time test was used.
• Participants included novice drivers (1, 5, 9 months post-licensing) and experienced drivers.
• A secondary task was introduced to simulate increased mental load.

Main Results:

• Average reaction times showed a non-significant trend towards decrease with experience.
• Significant differences were observed for specific test items, suggesting a potential experience effect.
• Male novice drivers under mental load showed longer reaction times compared to female novices and experienced male drivers.

Conclusions:

• Hazard perception, as measured in this study, appears to be a minor factor in explaining the initial reduction in novice driver crash risk.
• Driving experience may influence specific aspects of hazard perception.
• Mental load disproportionately affects hazard perception in male novice drivers.
