Perhaps the biggest cause of flood-related deaths and injuries is lack of public understanding of the severity and danger involved in floods and flash floods. Even though the water might look only inches deep, it could be much deeper and with very strong currents. Most trucks, four-wheel drive, and sports utility vehicles also are susceptible to being swept away by high water. Such vehicles often give motorists a false sense of security, believing the vehicles are safe under any conditions. This belief results in deaths or emergency rescues of motorists in vehicles either stuck in or swept away by flood waters.
