What should you do if the traffic signal turns red just before you enter an intersection?

When the traffic signal turns red just before you enter an intersection, the correct course of action is to stop. Traffic signals are designed to control the flow of vehicles and pedestrians safely. A red light indicates that you must stop and wait until the signal changes to green. This is crucial for your safety as well as the safety of others, including pedestrians who may be waiting to cross the intersection.

Stopping at a red light prevents potential collisions that could occur if you were to continue through the intersection when it is not safe to do so. It also allows time for vehicles and pedestrians that may have the right of way to clear the intersection.

In contrast, the other options suggest actions that could lead to dangerous situations. Slowing down and checking for vehicles might imply that it's okay to proceed if the way is clear, when in fact the law requires you to stop at a red light. Accelerating to cross the intersection quickly not only ignores the red signal but could result in serious accidents. Yielding to oncoming traffic would also be inappropriate since the traffic signal clearly dictates that you should stop. Understanding the rules of traffic signals is critical for maintaining safety on the road.
