What should you do if your vehicle starts to hydroplane?

Increase speed
Shift into neutral
Avoid abrupt steering
All of the above

The correct answer is: Avoid abrupt steering

Hydroplaning is a dangerous situation when a vehicle's tires lose contact with the road due to a layer of water. Increasing speed (A) can make your vehicle harder to control and prolong the hydroplaning. Shifting into neutral (B) can also be dangerous as it can cause your vehicle to lose power and make it more difficult to maneuver. The best course of action is to avoid abrupt steering (C) and gradually ease off the gas to slow down until your tires regain traction. While (D) may seem like the safest option, it is not advised to follow all of the above steps when hydroplaning.
