The loss of traction most difficult to identify quickly is what?

• A. Hydroplaning
• B. Skidding
• C. Brake failure
• D. Tire blowout

Answer: (A)

Hydroplaning is when a thin layer of water builds between the tires and the road, causing the tires to ride on top of the water rather than gripping the surface. This loss of traction is hard to identify quickly because you can still be moving and feel only a slight change in how the car responds; the steering and braking may seem normal at first, so the warning signs are subtle. You might not notice until you try to turn or slow down and find that the tires aren’t gripping as they should, which can happen suddenly on wet pavement.

Other problems tend to reveal themselves more quickly: skidding usually shows as the vehicle sliding or turning abruptly, brake failure is felt in the braking pedal and braking distance, and a tire blowout is often immediately noticeable with a loud pop and rapid loss of control. When hydroplaning is present, the safest response is to ease off the accelerator gently, avoid hard braking or sharp steering, and slow down gradually until you regain traction.
