Which factor can significantly affect a vehicle's stopping distance?

Weather conditions play a crucial role in determining a vehicle's stopping distance. When surfaces are wet or icy, they become slippery, reducing tire traction. This leads to longer stopping distances as the vehicle is more likely to skid rather than come to a quick stop. Factors such as rain, snow, frost, or even strong winds can impact how a vehicle handles and how quickly it can safely come to a stop. Drivers must adjust their following distance and speed according to these weather conditions to maintain safety on the road.

The other factors, such as the color of the vehicle, number of passengers, and type of fuel used, do not significantly impact stopping distance in the same way. While the number of passengers can affect the weight of the vehicle, which in turn may slightly influence stopping power, it is not as critical as weather conditions. Similarly, the vehicle's color has no bearing on its stopping capabilities, nor does the type of fuel affect braking performance. In essence, understanding how weather conditions affect vehicle control is essential for safe driving practices.
