What is the best indicator of a vehicle’s stopping ability?

The best indicator of a vehicle's stopping ability is the braking system condition and load weight. The braking system is crucial because it directly affects how quickly and effectively a vehicle can come to a stop. Factors such as the type and condition of the brakes—whether they are well-maintained or worn—determine how efficiently a vehicle can respond when the driver applies the brakes.

Additionally, the load weight of the vehicle plays a significant role in stopping distance. A heavier load requires more distance and time to stop compared to a lighter load. Therefore, understanding both of these aspects—the performance of the braking system and the weight being carried—provides clear insight into a vehicle's overall stopping capability.

While the driver's experience, tire type, and weather conditions can influence driving performance and safety, they are not as fundamental as the actual braking system and the load weight in determining how effectively a vehicle can stop. The brakes themselves and the amount of weight they have to manage are the primary factors in stopping power.
