Seek shelter immediately. If you are driving when you hear a tornado warning or see a tornado on the ground, get out of the vehicle immediately and seek shelter in a nearby building. If there is no time to get indoors, your chances of survival are better if you get out and lie in a ditch or low-lying area away from the vehicle. Cover your head and neck. Never try to follow or out-drive a tornado.
Tornadoes can change direction quickly and can lift up a car or truck and toss it through the air.
Remember, if you see a tornado on the ground, seek shelter immediately. Stop, look and listen. When a tornado watch is issued, the simplest advice is still the best. Stop going outside, and stop sitting or standing by doors and windows. Tornado winds can toss debris with tremendous force and shatter even well protected doors and windows.
