Question: 1 / 400

What factor can affect the braking distance of a commercial vehicle?

The speed of the vehicle

The weight of the vehicle and road conditions

The braking distance of a commercial vehicle is influenced by several factors, including the weight of the vehicle and the road conditions. Heavier vehicles require more distance to come to a complete stop due to their greater momentum. When a vehicle is heavier, it also means that it takes more force to decelerate effectively. Additionally, road conditions such as wet, icy, or uneven surfaces can significantly affect braking distance. For example, on a wet road, the tires may lose traction, increasing the distance needed to stop safely. Understanding these factors is crucial for safe driving, especially in commercial vehicles that often carry heavy loads and operate under varying conditions.
