Iowa Statistics

The Iowa Department of Transportation does not maintain statistics on aggressive driving. Although there is no specific category for aggressive driving, violations such as following too close, running stop signs and stop lights, speeding and improper lane change can all be elements of an aggressive driving behavior, especially if they are coupled with traffic crashes.
