Question

Difficulty: MediumDriving in Adverse Weather and Low Visibility

When driving on roadways covered with standing water, slush, or ice, activating your vehicle's cruise control system helps prevent hydroplaning by maintaining a steady speed.

Answer: Answer

Answer

False. Cruise control must be turned off in rain, snow, or icy conditions because automated throttle adjustments can accelerate wheel spin during hydroplaning or skid events.
The correct evaluation is False. Drivers should never use cruise control when roads are wet, icy, or slick. If a vehicle begins hydroplaning while cruise control is enabled, the system can attempt to maintain target speed by accelerating, causing the drive wheels to spin faster and causing the driver to lose steering and braking control.

Step-by-Step Solution

1
Analyze how cruise control operates during reduced road friction.
The cruise control system continuously feeds power to the drive wheels to maintain a set speed without sensing surface traction.
Understanding system mechanics is essential for recognizing driving hazards on slippery roads.
2
Evaluate the risk when hydroplaning or slipping occurs with cruise control active.
When tires lose contact with the road, the system senses a speed drop and increases engine power, spinning the wheels faster.
Spinning drive wheels significantly worsens traction loss and prevents natural engine braking from slowing the vehicle.
