Can Teen Drivers’ Risk Perceptions of Cannabis-Impaired Driving Be Calibrated via Driving Simulation Exposure? A Pilot Study

Abstract

Cannabis use among teens is rising with legalization, while their perceived risk of driving under the influence of cannabis (DUIC) continues to decline. This study evaluated whether exposure to a simulated drive on a driving simulator paired with cannabis-impairment goggles can recalibrate teens’ DUIC risk perceptions. Sixty-two (62) high school juniors and seniors completed a risk perception survey before and after a 10-min simulated drive while wearing such goggles. Risk perception increased significantly post-exposure, with the change being consistent across gender, license status, and cannabis-use history. Participants rated the simulator exposure as highly effective, though these ratings were not significantly associated with changes in their risk perception. Driving performance data showed widespread speed-limit exceedances and modest lane-keeping disruption. These findings warrant controlled, longitudinal replication of this experiential prevention approach to better understand the role of experiential DUIC awareness approaches in risk perception.
