Severe weather significantly impacts truck operations, primarily by reducing both traction and visibility. When conditions such as rain, snow, ice, or fog are present, the roadway can become slippery, which diminishes the tires' grip on the surface. This reduction in traction can make it more challenging for a truck to maintain control, accelerate, and stop effectively, which is critical for safe driving.

Additionally, reduced visibility due to heavy precipitation, fog, or snow can impair a driver's ability to see other vehicles, road signs, and traffic signals. This is especially important for truck drivers, who operate larger vehicles that require longer stopping distances and more cautious maneuvering. As a result, during severe weather, drivers must adjust their speed, maintain a greater following distance, and remain alert for changing conditions to ensure safe operation. This adaptability is crucial for preventing accidents and maintaining safety on the road.
