What should you do if you need to stop suddenly?

When you need to stop suddenly, applying the brakes quickly and firmly is the most effective response. This action engages the vehicle’s braking system at full capacity, which allows for a more rapid deceleration, helping to prevent a collision. In situations where a sudden stop is required—such as when an obstacle unexpectedly appears in your path—immediate and decisive braking is essential for safety.

This method maximizes the vehicle's stopping power and can significantly reduce stopping distance if conditions allow. It's important to maintain control of the vehicle while doing this; drivers should also be aware of the road conditions and their vehicle's capabilities, as slippery surfaces or worn brakes might reduce efficiency.

Other options, such as using the horn or gradually reducing speed, do not provide the same level of immediacy needed in a sudden stop scenario and could potentially lead to accidents. Pulling over to the side of the road is not practical in emergency situations where a quick stop is required, as it may not be an option if you're in traffic or facing an immediate hazard.
