What is the safest action when you encounter bad weather while driving a commercial vehicle?

When driving a commercial vehicle in bad weather, slowing down and increasing your following distance is the safest action because poor weather conditions, such as rain, snow, or fog, can significantly affect road traction and visibility. By reducing your speed, you allow yourself more time to react to any sudden changes in the traffic or road conditions.

Increasing the following distance gives you a larger safety buffer, decreasing the likelihood of a collision, especially in slippery conditions where stopping distances are extended. This approach embodies a more defensive driving strategy that prioritizes safety over maintaining regular speed, which is crucial for the larger and heavier nature of commercial vehicles. It also helps prevent accidents that could result from sudden stops or evasive maneuvers in adverse weather.
