What is a key reason for a driver to activate their horn daily?

The key reason for a driver to activate their horn daily is to ensure it is functioning properly for safety. The horn is an essential component of a vehicle's safety features, designed to alert others of the vehicle's presence and signal intentions. Regularly testing the horn helps confirm that it is operational and can effectively communicate warnings to pedestrians, cyclists, or other drivers when necessary. This practice contributes to the overall safety of the driver and others on the road.

While the other options touch on various aspects of driving and vehicle functionality, they do not address the primary importance of the horn in terms of safety and communication during daily operation. Practicing safe driving and assisting in parking maneuvers are essential skills, but they are not directly related to the daily activation of the horn as a means of ensuring it works when needed for critical situations on the road.
