Final answer:
When a traffic light turns yellow at an intersection, you should prepare to stop if it is safe to do so, unless you are too close to the intersection to stop safely, in which case proceed with caution. Traffic signals help regulate vehicle speeds and enhance pedestrian safety. Compliance with traffic signals contributes to public safety.
Step-by-step explanation:
When you are approaching an intersection and the traffic control light is yellow, the appropriate action to take is to prepare to stop, if it is safe to do so. The yellow light indicates that the signal is about to change to red, which means you must clear the intersection. If you are too close to the intersection to stop safely, you should proceed through with caution. However, you should never speed up to try to "beat" the yellow light, as this can be dangerous and violate traffic laws.
The presence of a traffic signal at an intersection generally helps to regulate the flow of traffic and increase pedestrian safety. Traffic signals are installed to address issues like speeding vehicles that do not adhere to the posted speed limit and to help reduce the number of accidents, some of which can be fatal. For pedestrians, particularly in areas of high foot traffic such as near a campus, traffic signals provide designated times to cross, enhancing safety.
In summary, always be prepared to stop at a yellow light if it is safe to do so, to ensure safety for yourself, other drivers, and pedestrians at the intersection.
