Road rage can include:

1. Shouts, excessive use of a horn or obscene gestures and threats.
2. Driving actions like when you cut off another vehicle, drive too closely, block another vehicle so it can not use a traffic lane, chase another vehicle or run it off the road, deliberately slam into a vehicle.
3.  When you stop a vehicle at the side of the road, get out to threaten, attack, fight or injure another motorist or passenger or a pedestrian, bicyclist or other person.

Research indicates that being in a state of rage can affect your blood pressure and your ability to reason and make decisions. As a driver, you will make more errors. The chance of being involved in a traffic crash will increase.
Aggressive driving and road rage can lead to revoked or suspended driver licenses, problems between family members and friends, loss of employment and legal problems.
Many drivers do not recognize when their own aggressive driving or road rage is affecting their ability to drive safely. State law requires every DMV-approved
accident prevention course to address the hazards and dangers of road rage. For
information about DMV-approved accident prevention courses, see the publication
Point & Insurance Reduction Program (C-32A), available from the DMV Internet
Office. You can also contact one of the program sponsors. Information available at
any state or county motor vehicle office.
