It's not clear from all the participants in this thread that the safe, intelligent, responsible and classy response to road rage is understood.
- Make no eye contact with the enraged person or any person beginning to yell or utter profanities or threats.
- Do not utter anything, especially profane words or threats, and make no gestures other than necessary directional hand signals
- Maneuver to avoid them and get away as soon as possible.
If leaving the scene is delayed because a collision has already occurred, eye contact can still be avoided. I won't detail what to do after a collision here, but it suffices that escalation is not necessary or desireable. If law enforcement is not involved or until they arrive and take control of the situation, avoid and decline all arguments, insults, or verbal combativeness. Render aid or receive aid as necessary without hostility. Exchange identification or insurance information without unnecessary comment. The correct place for any necessary argument or settement of dispute is in court. Any comment you make has a high probability of being recorded, and if it is made without the benefit of careful forethought and legal counsel, is likely to be to your disadvantage.
