What does a green light mean at an intersection?

A green light at an intersection indicates that vehicles are permitted to proceed through the intersection, but only if the way is clear. This means that drivers should ensure there are no obstacles, other vehicles, or pedestrians in their path before moving forward. It's essential for safety that drivers remain vigilant and aware of their surroundings even when they have the right of way, as unexpected situations can arise.

The other choices relate to different traffic scenarios. Stopping and waiting occurs with a red light, allowing vehicles to remain stationary until the signal changes. Proceeding with caution might be a consideration at a yellow light, which warns drivers to prepare to stop, as the light is about to change to red. Yielding to pedestrians is a requirement at all times, particularly when they are in a crosswalk or have the right of way, regardless of the traffic signal's color.
