A Comparison of the Hazard Perception Ability of Matched Groups of Healthy Drivers Aged 35 to 55, 65 to 74, and 75 to 84 Years

This article reports on a study that compared different age groups of drivers on their abilities to perceive road hazards. The authors examined differences in response latencies obtained during a validated, video-based hazard perception driving test in three healthy, community-dwelling groups: 22 mid-aged (35-55 years), 34 young-old (65-74 years), and 23 old-old (75-84 years) current drivers, matched for gender, education level, and vocabulary. The results showed no significant difference in performance between mid-aged and young-old groups, but the old-old group was significantly slower than the other two groups. Factors considered include useful field of view (UFOV), contrast sensitivity, and simple reaction time measures. The authors conclude that their study results are consistent with the idea that increased crash risk in older adults could be a function of poorer hazard perception, though this decline does not appear to manifest until age 75 or older in healthy drivers.
