Unless you're a Delaware police officer on traffic duty, you can't do much about another driver's behavior. You might be able to safely distance yourself from a motorist acting recklessly. Then again, high levels of traffic, highway speeds and other issues could prevent you from escaping a collision, especially if there's an enraged driver in your midst.
Road rage is serious problem in Delaware and throughout the country. It's one thing to make an angry face at another motorist while driving. It's quite another to cut a driver off or otherwise use a vehicle for aggressive purposes out of anger on the road. The latter causes many collisions and serious or even fatal injuries.
