What does a yellow traffic light indicate?

A yellow traffic light indicates that the light is about to turn red, signaling drivers to prepare to stop. This warning provides essential time for drivers to make a decision about their next actions. It is important for ensuring the safety of all road users, as it helps prevent accidents that can occur when vehicles continue through an intersection blindly expecting the light to remain green. The yellow light serves as a transition phase where drivers should assess their situation—if they are too close to the intersection to stop safely, they may proceed with caution, but the primary intent of the yellow light is to alert drivers to be ready to stop. It conveys critical information that prevents confusion on the road, allowing drivers to respond accordingly and thus promoting overall traffic safety.
