You're driving and see a tornado approaching.
Wrong response: Take shelter under an overpass as soon as possible.
Smart move: If traffic is light and you can see that the tornado is distant, try to drive out of its path by moving at a right angle to it. Otherwise, park your car and go inside a sturdy building, says Roger Edwards, a meteorologist at the Storm Prediction Center. If you're in open country, run to low ground away from cars and trees, which could be blown onto you. Lie facedown, protecting the back of your head with your arms, and tell your children to do the same. "Seeking shelter under a bridge or an overpass offers little protection against deadly flying debris," Edwards says.
