Road rage is a term used to refer to violent behavior by a driver of an automobile, which thus causes accidents or incidents on roadways. It can be thought of as an extreme case of aggressive driving.

The following are common manifestations of road rage:

Generally aggressive driving, including sudden acceleration, braking, and close tailgating.
Cutting others off in a lane, or deliberately preventing someone from merging.
Sounding the vehicle's horn or flashing lights excessively.
Rude gestures (such as the finger).
Shouting verbal abuse or threats.
Intentionally causing a collision between vehicles.
Getting out of the car to attempt to start a confrontation, including striking someone else's vehicle with an object.
Threatening to use or using a firearm or other deadly weapon.
Throwing objects from a moving vehicle with the intent of damaging other vehicles.

The average number of incidents per road rager is 27. That means that most of us will encounter road ragers many times in our lives. Road rage can lead to injuries or even death. Tens of thousands of accidents each year can be linked directly to aggressive driving, including road rage, and is now a leading cause of death for young children.
