What should a driver do when encountering slippery roads or poor visibility?

Maintaining the maximum speed limit under slippery road conditions or poor visibility is not advisable because it does not take into account the altered driving conditions that require a more cautious approach. On slippery roads, such as those that are wet, icy, or covered in snow, friction between the tires and the road surface is reduced. This means that vehicles can lose traction more easily, leading to a higher risk of skidding or losing control.

In poor visibility conditions, such as fog, heavy rain, or nighttime driving, drivers may not be able to see obstacles, road signs, or other vehicles clearly. Continuing to drive at top speeds under such circumstances compromises safety, as it limits the driver's reaction time and ability to respond to hazards.

Drivers are taught to adapt their speed to match the road conditions, which typically involves reducing speed to maintain control of the vehicle and ensure a safe reaction time for any sudden changes or obstacles that could arise. Thus, the correct response is to reduce speed immediately, allowing for better handling and safety under adverse conditions.
