What does a green light mean at an intersection?

A green light at an intersection signifies that you may proceed through the intersection if it is safe to do so. This means you have the right of way and can continue driving without needing to stop, assuming that there are no other restrictions such as pedestrians crossing or other vehicles occupying the intersection. It is essential, however, to assess the situation, including checking for any vehicles or pedestrians that may not be following the rules, to ensure a safe passage through the intersection.

Other options present misunderstandings of traffic signals. Coming to a complete stop before proceeding is necessary only when a red light is displayed. Yielding to oncoming traffic is not required when you have a green light unless you are making a turn that may conflict with other vehicles. Always proceeding with caution is advisable at all times but is not the specific meaning of a green light, which explicitly allows you to go when it is safe.
