What does a green light mean at a traffic signal?

A green light at a traffic signal indicates that you may proceed through the intersection if it is safe to do so. It signifies that the traffic is given the right of way to continue moving, provided there are no obstacles or hazards in your path. This means that as a driver, you should assess the situation, check for any pedestrians or other vehicles, and ensure that the way is clear before you move forward.

The other options represent different traffic signal meanings. Stopping is required at a red light, preparing to stop is associated with a yellow light, and a pedestrian crossing typically has its own dedicated signals to ensure the safety of those crossing the road. Understanding the meaning of traffic signals is crucial for safe driving and to ensure compliance with road laws.
