The U.S. Census Bureau predicts there will be 9.6 million people 85 and older by 2030, many of whom may still be on the country’s roadways. Fatality rates for drivers increase after age 65, according to a study by Carnegie Mellon University and the AAA Foundation for Traffic Safety. For drivers 85 and older, the fatality rate jumps considerably, to about four times higher than the fatality rate for teenagers.
