According to a new study by the AAA Foundation for Traffic Safety, nearly 80 percent of U.S. drivers expressed significant anger, aggression, or road rage behind the wheel at least once in the past year. The most alarming findings suggest that approximately eight million U.S. drivers engaged in extreme examples of road rage, including purposefully ramming another vehicle or getting out of the car to confront another driver. Many drivers reported engaging in the following types of road rage:

• Purposefully tailgating: 51 percent
• Yelling at another driver: 47 percent
• Honking to show annoyance or anger: 45 percent
• Making angry gestures: 33 percent
• Trying to block another vehicle from changing lanes: 24 percent

One of the study's researchers concluded, "Inconsiderate driving, bad traffic and the daily stresses of life can transform minor frustrations into dangerous road rage. Far too many drivers are losing themselves in the heat of the moment and lashing out in ways that could turn deadly."
