Because two symptoms of depression are a feeling that the world is out to get you and anger, it is very easy to succumb to road rage. This is dangerous as it can lead to physical confrontation, as well as other dangerous actions. It is important to find ways to keep calm and maintain control when you don't have the option of walking away.

The first thing to do is to slow down. When getting angry, the natural instinct is to speed up, but by doing that you are just going to instigate things. Slow down and let the problem move away from you. If that isn't an option, then move your car around a little bit. Involve yourself in changing lanes or the radio. Keep your eyes on the road, but make an effort to not think about whatever is instigating you.

If all else fails, pull over. You can always do that, even if you are on a highway (go to the next exit or pull onto the shoulder if it is not for a while). Stop for a bit, and take some deep breaths. Review your meditation techniques and find a way to calm yourself down. Remember: the world is not out to get you, and whatever happened, it is not that important. Moving on from these incidents is the most important thing that you can do.
