When is it especially critical to use your horn?

1. During heavy traffic

2. When you need to park your vehicle

3. To alert other drivers of your presence in risky situations

4. When approaching traffic lights

The correct answer is: To alert other drivers of your presence in risky situations

Using your horn is especially critical to alert other drivers of your presence in risky situations because it serves as a vital safety tool. When visibility is compromised or when another driver may not see you, the horn can draw their attention and help prevent accidents. This is particularly important in situations where the potential for a collision is heightened, such as when a vehicle is about to enter your lane without seeing you or when pedestrians are in your path. In scenarios with heavy traffic or while parking, while signaling intentions can be helpful, those situations do not carry the same urgency or risk as those where quick action may prevent harm. When approaching traffic lights, using the horn is typically unnecessary unless there is a very specific danger that needs addressing, as most drivers will be aware of traffic light signals. Therefore, the correct answer highlights the importance of using the horn to enhance safety in critical moments on the road.
