The Maine Department of Transportation reported in its Strategic Highway Safety Plan in 2011 that drivers older than the age 65 are in more crashes per mile driven than any age group besides 16-year-olds. Center for Disease Control reports fatal motor vehicle accident rates increase starting at age 75 and increase notably after age 80, with an average of 500 seniors involved in motor vehicle accidents each day.

Maine DOT attributes higher crash and injury rates to "gradually diminishing physical, sensory and cognitive capabilities, often exacerbated by medications and specific conditions, and increasing physical frailty, which renders motor vehicle crashes more grave for the elderly drivers themselves."

The department is developing assessment tools to identify individuals most at risk if they continue driving and has set a goal to improve access to transportation systems to ease the transition for those who can no longer drive, according to its Strategic Highway Safety Plan of 2011.

While the CDC reports that seniors generally take more safety precautions than other drivers by using seat belts, observing speed limits, limiting driving in poor conditions, and avoiding drinking and driving, it also lists a number of additional practices older drivers can adopt to stay safe on the road.

These include exercising regularly to maintain flexibility, reviewing medications with doctors to reduce side effects or interactions, driving during daylight and good weather conditions, getting eyes checked once a year, avoiding distractions while driving, planning safe routes, and exploring alternatives to driving.
