What does a red light mean at an intersection?

A red light at an intersection is a clear and universal signal indicating that vehicles must stop and not proceed until the light changes to green. This rule is crucial for ensuring the safety of all road users, including pedestrians, cyclists, and other vehicles.

When a driver sees a red light, they are required to bring their vehicle to a complete stop at the designated stop line or before entering the crosswalk (if there is one) or intersection. It is essential to wait until the light turns green before moving forward to avoid accidents and potential violations of traffic laws.

The other options may suggest actions that could compromise safety or are not in line with traffic regulations. For example, preparing to stop does not imply a complete halt, which is necessary at a red light, and going with caution or accelerating through the intersection directly contradicts the fundamental directive of a traffic signal.
