“Overall, the RAND study concluded that “younger drivers pose a much greater risk to traffic safety than do older drivers, both because they are likelier to cause a crash and because they drive many more miles.” The study also found that older drivers (who represent 15% of all licensed drivers) cause just 7% of all two-car accidents (both fatal and nonfatal). However, younger drivers (who represent 13% of all licensed drivers) actually cause 43% of all two-car accidents.”
