Danger spots lurking in communities
Water tends to collect in underpasses beneath railroads or streets, because they are lower than their surroundings. When flooded, underpasses are extremely dangerous, requiring fast pumps.
What is an underpass?
An underpass is where the ground level has been lowered to allow a road to pass underneath another road or railroad.
When heavy rain falls, rainwater from the surrounding area flows to this low spot, often resulting in flooding.
It is very difficult to tell the real depth of water in a flooded underpass or what may be hidden under the water. Always avoid any flooded underpasses you encounter and find a way around, instead.
What happens when you enter a flooded underpass?
If the water height exceeds the floor of the vehicle, the engine and electrical systems will fail.
When the water reaches halfway up the vehicle doors, the doors can no longer be opened from the inside.
When the water gets even deeper, the vehicle begins to float and moves with the water current.
