What is the correct approach if a commercial driver encounters poor weather conditions?

Reducing speed and increasing following distance is the appropriate response when a commercial driver faces poor weather conditions. Adverse weather such as rain, snow, fog, or ice can significantly affect vehicle handling and braking distances. By slowing down, the driver can maintain better control of the vehicle, allowing for a more measured response to any sudden changes in road conditions or traffic situations.

Increasing the following distance is equally important because it provides additional time to react to obstacles or changes in speed of other vehicles. In poor weather, stopping distances can be considerably longer, so maintaining a greater distance helps to ensure that the driver has enough time and space to stop safely if necessary.

The other choices do not contribute to safe driving under poor weather conditions. Speeding to reach a destination faster compromises safety and increases the likelihood of losing control. Maintaining speed can lead to dangerous situations, particularly if roads are slick or visibility is reduced. Using high beams can further reduce visibility when driving at night or in fog, as the light reflects off moisture in the air and creates glare. Therefore, the correct approach is to reduce speed and increase following distance to prioritize safety on the road.
