“…Drivers more than sixty years of age are more likely than younger drivers to have fatal accidents, given equal mileage-estimated risk exposure (NHTSA, 2001;Yanik, 1986), and daytime fatality risk is higher for drivers over seventy-five than for any other age group (Massie, Campbell & Williams, 1995). Physical frailty accounts for some of the fatality risk increase (Evans, Gerrish, & Taheri, 1998;Li, Braver, & Chen, 2003).…”

“…Collisions per mile increase after the age of 65, and accelerate substantially after the age of 70 (Massie, Campbell & Williams, 1995;NHTSA, 2001;Yanik, 1986), although these statistics may be biased regarding older drivers for several reasons (Hakamies-Blomqvist, 2004), including overexposure to collision risk from compensatory changes to driving practices (Janke, 1991).…”

Summary: Motion contrast thresholds for 0.4 cycle/degree drifting Gabor stimuli were assessed at 15-degrees eccentricity for 16 younger drivers (ages 24 to 42), and 15 older drivers (ages 65 to 84), using a temporal two-alternative forced choice staircase procedure. Two self-report questionnaires assessed detection failure accident risk-the Driver Perception Questionnaire (DPQ5), and an abridged Aging Driver Questionnaire (ADQ15). The UFOV ® test battery was also administered. Mean peripheral motion contrast thresholds (PMCT) of younger and older participants were -39.3 dB and -33.8 dB, respectively. For younger drivers, the correlation between PMCT and DPQ5 scores was .62 (p<.01), and between DPQ5 and ADQ16 (new and validated self-report measures, respectively) was .59 (p<.01). For older drivers, correlation between PMCT and DPQ5 scores was .49 (p<.01), between DPQ5 and ADQ16 was .73 (p<.01), and between PMCT and age was .49 (p<.05). For drivers overall, correlation was .48 (p<.01) between PMCT and DPQ5 scores, .63 (p<.0001) between DPQ5 and ADQ16, and .69 (p<.0001) between PMCT and age. For drivers overall, correlation was .30 (p<.05) between UFOV1 and age, .67 (p<.0001) between UFOV2 and age, .56 (p<.001) between UFOV2 and PMCT, .80 (p<.0001) between UFOV3 and age, and .58 (p<.001) between UFOV3 and PMCT. Holding age constant, partial correlation of PMCT with DPQ5 was .55 (p<.001), and of PMCT with ADQ15 was .39 (p<.05). PMCT significantly predicted self-reported driving performance in a laboratory setting, and worsened significantly with age. PMCT assessment should be made practicable. Informing high-risk drivers may encourage appropriate risk reduction countermeasures.
