A steady green light indicates what?

Answer: B — You can go through the intersection

A steady green light signals that drivers may proceed through the intersection. This light indicates that it is safe to continue moving forward unless there are other factors, such as pedestrians crossing or vehicles already in the intersection. It is important for drivers to remain alert, as while they may go through, they should still watch for unexpected situations that could require them to stop. The other options suggest actions that are not appropriate when facing a steady green light. Slowing down and preparing to stop, merging left immediately, or preparing to yield are responses that would typically correspond to a yellow or red light, or specific traffic control measures. Therefore, understanding the function of a green light is crucial for safe driving and proper navigation at intersections.
