What must be done when a traffic signal turns green?

When a traffic signal turns green, it is essential to check for pedestrians and cross traffic before proceeding. Even though the green light indicates that you have the right of way to move forward, it does not guarantee that the intersection is clear of potential hazards. Pedestrians may still be crossing, and vehicles from the opposite direction may be turning or running a red light.

Taking the time to look for pedestrians ensures their safety, and observing cross traffic helps you assess the situation fully before you enter the intersection. This practice promotes safe driving and helps prevent accidents, making it a critical step in responding to a green traffic signal.

The other options involve actions that could be unsafe. Immediately accelerating might lead to a collision if there are obstacles or pedestrians in the way. Changing lanes can also be dangerous without confirming that other vehicles are not in your blind spots or that it is safe to maneuver. Staying stopped is unnecessary when the light is green, as you have the right to proceed, provided the area is clear.
