According to the AARP, the number 1 traffic violation committed by drivers aged 50 and over is failure to observe right-of-way.
The number 2 traffic violation committed by drivers over 50 is improper left turn. Failure to obey left turn signs and signals, improper positioning of the vehicle and misjudging the speed of oncoming vehicles are the most common reasons for this problem.
Also, drivers over 55 are involved in more accidents per mile driven. The number of miles must be taken into account in order to accurately compare older and younger drivers. The number of accidents per mile rises sharply at about age 75.
