Hydroplaning occurs on surfaces where water has collected. If there is enough water, vehicles can hydroplane at speeds as low as 30 mph. Hydroplaning becomes more likely if tires are under-inflated or if the tread is worn.

When tires are properly inflated.

A good amount, such as a large puddle

Before a trip, ensure that air in the air brake system reaches all trailers. Do this by waiting for air pressure to build, then sending air to both the emergency and service lines and opening the shut-off valves on the rear of the last trailer. If air escapes from the shut-off valves in the rear of the combination, the air is being supplied to the entire vehicle.

Listening for air at the rear shut-off valve.

Checking for moving air inside of each trailer.
