Research shows how easily floodwater can wash cars away

Engineers have discovered just how easy it is for a vehicle to be swept away by floodwater.

Tests show that attempting to move through even lightly flooded roads can be incredibly dangerous.
Once the water reaches the floor of the car, it becomes extremely susceptible to being washed away by even the smallest of currents.

In footage released by the University of New South Wales, a Nissan Patrol 4x4 is placed in a tank, which is then filled with water. The 2.5-tonne vehicle became unstable with the water level at 45cm, and once it reached 95cm the vehicle began to float.

The results were even more shocking for smaller cars. In another test, a one-tonne Toyota Yaris underwent the same test and was at risk of being swept away by just 15cm of water.
