Yes, yes you should, but only as a last resort if no other shelter is available.
When you see a tornado, go into a secure building or if there are none near you, huddle in a nearby ditch.
To some degree. You should only take cover in a ditch from a tornado as a last resort if no shelter is available.
Lie in a ditch or depression in the ground if you cannot get to shelter.
If you cannot get to any safe shelter or even a ditch during a tornado, lie flat on the ground.
Do not try to outrun it. It may be the last thing you ever do. Instead, get out of the car and seek shelter, be it a house or building or a ditch
Well this depends where you are if you are at your home you should get to your basement. If you were driving down the street and a tornado comes you should find a sturdy building or, if none is available, a ditch.
If the tornado is relatively close and no other shelter is available then yes. Tornadoes are fast moving and unpredictable, you should not attempt to outrun one.
get in a ditch
If no shelter is available lie in a ditch. Do not seek shelter under a bridge.
If you are not in a ditch, try to find one nearby. If none is available, find a low spot and lie flat on the ground.
No. You should take cover in a ditch only as a last resort if no other shelter is available. A ditch is simply better than being completely exposed. The only truly safe place is underground or in a reinforced enclosure such as a tornado shelter or bank vault.
If you are caught out doors during a tornado, it is best to find an underground area where the wind can't reach. Don't go somewhere where the wind can flow through as it will possibly intensify wind speeds.
