What adjustment should a driver make when traveling on snowy roads?

When driving on snowy roads, it is crucial to reduce speed to maintain control of the vehicle. Snow reduces the amount of traction between the tires and the road surface. This decreased traction can lead to skidding or loss of control if a driver is traveling too fast. By slowing down, a driver allows more time to react to poor road conditions and reduces the risk of losing control, making it easier to stop or maneuver safely.

Increasing speed, as suggested in another option, can worsen traction issues, making it more difficult for tires to grip the road. Additionally, turning off the anti-lock brakes compromises a vehicle’s safety feature designed to prevent wheel lock-up during braking. Using cruise control is not recommended on snowy roads, as it can lead to unintentional acceleration on slippery surfaces, increasing the risk of an accident. Therefore, the appropriate adjustment is to reduce speed to ensure safer driving in snowy conditions.
