You’re driving along a wet road. How can you tell if your vehicle’s tyres are losing their grip on the surface?

Explanation: If you drive at speed in very wet conditions, your steering may suddenly feel lighter than usual. This means that the tyres have lifted off the surface of the road and are floating on the surface of the water. This is known as aquaplaning. Reduce speed but don't brake until your steering returns to normal.
