Which statement is correct regarding a green traffic light?

The statement that emphasizes proceeding only if it is safe is correct regarding a green traffic light. While a green light indicates that vehicles are allowed to go, it is crucial to ensure that the intersection is clear and that it is safe to proceed. Drivers must remain vigilant for any pedestrians crossing the street, other vehicles that may not be obeying traffic signals, or any obstacles that could pose a danger.

This cautious approach ensures not just compliance with traffic laws but also promotes safety for all road users. It's important to remember that a green light doesn't guarantee that the way is entirely clear.

The other statements imply immediate or expedited actions that may overlook the necessity to assess the surrounding conditions. For instance, going immediately or speeding up might encourage risky behavior in situations where caution is warranted. Stopping only if the light changes ignores the possibility of encountering situations that require a driver's discretion prior to proceeding, such as pedestrians or vehicles that may have entered the intersection despite the light being green.
