Summary

This report, commissioned by the AAA Foundation for Traffic Safety in 1997, addresses the growing public concern regarding aggressive driving and "road rage." Motivated by surveys indicating that motorists felt more threatened by aggressive drivers than by drunk drivers, and by high-profile fatal incidents, the Foundation sought to determine the true extent, trends, and characteristics of this phenomenon. The document primarily presents a study by Louis Mizell, which analyzes reported incidents of violence involving traffic altercations, alongside supplementary papers on road rage psychology. Mizell’s study compiled a database of 10,037 aggressive driving incidents reported between January 1990 and September 1996. Data were sourced from 30 major newspapers, 16 police departments, and insurance company claims. The study defined aggressive driving as intentional injury or killing resulting from a traffic dispute. The analysis examined perpetrator demographics, victim profiles, weapons used, and specific triggers, such as domestic violence spillover, racial hate, and attacks on law enforcement. The findings reveal a steady increase in reported incidents, rising from 1,129 in 1990 to an estimated 1,800 in 1996. These incidents resulted in at least 218 murders and 12,610 injuries. The data indicate that while perpetrators are often young males with criminal histories or substance abuse problems, there is no single profile; successful individuals without prior records also commit such acts. Firearms (37%) and vehicles themselves (35%) were the most common weapons. Triggers were frequently trivial, such as lane changes or parking disputes, acting as catalysts for underlying stress. Specific subsets included 322 incidents involving domestic violence, 221 attacks on police officers, and 94 crashes into buildings. Female perpetrators accounted for 413 incidents, predominantly using their vehicles as weapons. The report concludes that aggressive driving is a significant safety hazard driven by cumulative stressors rather than isolated events. It emphasizes that anyone can become an aggressive driver and provides extensive advice for motorists to mitigate risk. Recommendations include avoiding provocative behaviors like tailgating, using obscene gestures, or blocking traffic, as well as managing personal stress through schedule adjustments and attitude changes. The study underscores the need for public awareness and behavioral modification to reduce the incidence of violent traffic altercations.

Key finding

Mizell's database of 10,037 violent U.S. traffic altercations (1990-1996) found firearms used in 37% of cases and the vehicle itself used as a weapon in 35%, often triggered by minor traffic disputes.
