There are times when you see a car crash coming just before it actually happens. It might be because you hit an inopportune patch of ice or because you see someone barreling through an intersection and you don't have time to stop before you hit them. In any regard, you can make sure that you lessen your chances of getting seriously injured by remembering that there still may be time to react.
Step 1: Know Where to Go
Make sure you pay attention to side roads, sidewalks and other paths of travel that might get you out of the way. These are called escape routes. You should constantly be surveying the road ahead for them. For example, if you know you can cut left at an intersection without hitting anyone, you may be able to veer away from a driver who negligently turns in front of you.
Step 2: Train Yourself
Your number one resource in a fast and dangerous situation is training. If you haven't taken driver's ed since high school, it's time to take a defensive driving course. They're actually pretty enjoyable and the skills you get may well save your life someday, or someone else's.
