When is it appropriate to use your horn while driving?

1. To greet other drivers

2. To alert others of your presence

3. To express frustration

4. To indicate a lane change

The correct answer is: To alert others of your presence

Using your horn to alert others of your presence is appropriate as it serves a safety purpose. Horns are primarily meant to communicate with other road users, particularly in situations where their awareness of your vehicle could prevent an accident. For instance, if a pedestrian is crossing the road without noticing your approaching vehicle, a quick beep can make them aware of your presence and help avoid a potentially dangerous situation. In contrast, using your horn to greet other drivers is generally unnecessary and can be seen as distracting or confusing. Expressing frustration through honking may escalate situations or provoke aggressive responses from others, which is not conducive to safe driving. Indicating a lane change with your horn is also not standard practice; drivers should use indicators and mirrors for signaling their intentions on the road.
