If a person spots a nearby tornado while driving, the official National Weather Service directive has been for the individual to abandon the car and seek shelter in a ditch or culvert, or substantial shelter if nearby. Far-away, highly visible tornadoes, however, can be successfully fled from at right angles (90-degrees) from its direction of apparent movement. Despite dangers inherent with operating a vehicle during a tornado, given sufficient advance warning, mobile home residents have been instructed by the National Weather Service to drive to the nearest secure shelter during a warning.
