What must you do when you come up to a red light showing at traffic signals?

When approaching a red light at traffic signals, the appropriate action is to stop. This is a critical rule in traffic management and safety. Stopping at a red light ensures that you obey traffic signals, which are designed to control the flow of vehicles and pedestrians, preventing accidents and ensuring safety at intersections.

When the light is red, it indicates that you must yield to oncoming traffic and pedestrians who have the right of way. Only after the light turns green can you safely proceed, having confirmed that it is clear to do so. This practice is essential for maintaining order on the road and contributing to overall traffic safety.

While slowing down and preparing to stop or proceeding with caution might seem reasonable in certain scenarios, they do not align with the specific requirements of responding to a red traffic light, which mandates a complete stop. Continuing to drive when the light is red, even if the intersection appears clear, violates traffic laws and can lead to severe consequences, including accidents or penalties. Thus, stopping is the only acceptable action when faced with a red light at traffic signals.
