Question

question 11 of 18

hydroplaning is usually caused by:

• excessive speed.
• excessive stops.
• sudden stops.
• sudden turns.

Explanation:

Define hydroplaning and its physical cause

Hydroplaning occurs when a vehicle's tires lose contact with the road surface and ride on a thin film of water. This loss of traction prevents the vehicle from responding to control inputs like steering or braking.

Analyze the role of speed in hydroplaning

As speed increases, tires cannot displace water quickly enough. This causes water to build up underneath the tires, leading directly to hydroplaning. Therefore, Driver Education teaches that excessive speed on wet roads is the primary cause.

Evaluate the remaining options

Sudden stops, sudden turns, or excessive stops can cause skidding or loss of control on wet pavement, but they do not physically initiate the lifting of the tires onto a layer of water in the way high speed does.

Answer:

• excessive speed. (Correct answer)
• excessive stops.
• sudden stops.
• sudden turns.
