What immediate action should a driver take upon seeing a traffic-control signal indicating stop?

When a driver sees a traffic-control signal indicating a stop, the immediate and most appropriate action is to come to a complete stop. This requirement is in place to ensure the safety of all roadway users, including pedestrians, cyclists, and other vehicles. Stopping at a red traffic signal allows drivers to comply with traffic laws and regulations designed to minimize accidents and maintain order on the road.

Ignoring a stop signal by accelerating or attempting to find an alternate route not only violates traffic laws but also increases the risk of collisions. Additionally, honking the horn is not a suitable response to a stop signal; it does not serve any purpose related to traffic safety in this context and could potentially lead to confusion or distraction for other drivers. Therefore, stopping completely at a red signal is essential for following the law and contributing to safe driving practices.
