What does it mean if a light turns yellow at an intersection?

When a light turns yellow at an intersection, it indicates that the signal is about to change to red. This serves as a warning to drivers that they should prepare to stop safely. The intent of this signal is to ensure that drivers have sufficient time to react and come to a halt in a controlled manner, rather than rushing through the intersection.

The yellow light is a crucial part of traffic signal operations, designed to enhance safety for all road users by alerting them to an impending change in the traffic control. By preparing to stop, drivers help reduce the likelihood of accidents that can occur if they attempt to accelerate through the intersection. This understanding is vital for maintaining safe driving practices and complying with traffic laws.
