What is the limiting factor for a vehicle’s braking?
Active and passive safety
Explanation
The **tire's grip on the road** is the key factor that determines a vehicle's braking limit. This is because, when braking, a force is applied to the wheels to stop them, and this force is transmitted through the pads or shoes that rub against other elements of the wheels. The effectiveness of this process depends on the tire's ability to adhere to the road.
- **Road conditions**: If the road is wet or slippery, grip decreases, which can increase the braking distance.
- **Condition of the tires**: Tires in good condition improve grip, while worn tires can reduce it.
Other factors, such as **speed** and **vehicle load**, also influence the braking distance, but they are not the braking limit itself. Speed affects how much space is needed to stop, and the load can increase braking time, but both depend on grip to be effective. The number of passengers does not directly affect braking capacity.
