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. This means that vehicles facing a green light have the right of way to continue moving forward. However, it is essential to exercise caution and yield to pedestrians who may be crossing the intersection. This ensures the safety of all road users and helps to prevent accidents.

While it might be tempting to accelerate and move quickly through the intersection, caution is necessary. It's also important to remember that a green light does not mean you can ignore your surroundings or traffic laws; you should always be aware of potential hazards, such as pedestrians and other vehicles that may still be moving in the intersection. The other options do not accurately reflect the meaning of a green light and thus, are not applicable in this context.
