Final answer:
Seeking shelter under a highway overpass during a tornado is not safe. Tornadoes produce strong winds and flying debris that can be dangerous under an overpass. It is better to find a designated tornado shelter or a sturdy, low-lying building for protection.
Step-by-step explanation:
Seeking shelter under a highway overpass is not a good idea during a tornado. While it may seem like a safe option due to the open space and the structure providing some coverage, it actually increases the risk of injury or death. Tornadoes produce extremely strong winds that can create wind tunnels under overpasses, causing debris to accumulate and create dangerous flying projectiles. Additionally, the overpass itself can act as a wind tunnel, channeling and intensifying the wind speeds.
A safer option during a tornado is to find a sturdy, low-lying building or a designated tornado shelter. These structures are specifically designed to withstand the high winds and flying debris associated with tornadoes. They provide better protection against the destructive forces of the tornado and reduce the risk of injury.
