Document Summary
2051: 20% of the population will be old. Crashes: older adults are over represented in crash rates. Old adults are more likely to crash depending on the kilometres driven. Seniors 4x more likely to be seriously injured and hospitalized than are driver 16-24years. Treatment of injuries is more costly, recovery slower, less complete. Most (3 or more) older person crashes are multi-vehicle crashes. Vision: lower acuity and field of view, lower peripheral vision, lower depth perception, lower contrast sensitivity, lower night vision, higher sensitivity to glare, Perceptual and psychomotor: lower ability to judge distance and speed of moving objects, slower reaction times, Physical abilities: decreased flexibility and range of motion (neck, shoulders), foot problems. The diagnosis of dementia does not automatically mean no driving (some people with mild dementia can drive albeit for a limited period of time) Older drivers tend to: drive less often, shorter distances, less on busy highways and at night.
