When my wife turned 65 our auto insurance premium increased because of that fact. When we inquired that was the only reason given even though we have not had any accidents or traffic violations. I remember seeing a report on TV about a AAA study done on the relationship of different age groups on accident rates. Where can I get a copy of that study.
Your memory served you well! The AAA Foundation for Traffic Safety published a report in 2009 that looked at the risks that drivers of different age groups pose to other road users, as well as to themselves. Contrary to public perception, older drivers do not pose the greatest risk to other road users! You can read more about that finding and others here.
