ROAD RAGE: Vast Majority of US Drivers Exhibit Aggressive Behavior, New AAA Study Concludes.

The study, the purpose of which was to provide estimates of the prevalence of aggressive driving behaviors, found that 78 percent of respondents admitted to having engaged in at least one aggressive driving behavior in the last year.

The respondents were 2,705 licensed drivers questioned via a nationally representative online survey conducted in 2014 on their driving behavior in the previous year.

The most common behaviors found in the survey were purposefully following another vehicle too closely, yelling at other drivers, and honking to show annoyance or anger. About half of respondents admitted to engaging in at least one of these behaviors.

Left unsaid: How much aggressive driving is in reaction to passive-aggressive drivers going slowly in the left lane or on the highway onramp?
