The minimum green time ensures what for vehicles stopped at an intersection?

The correct answer emphasizes the importance of minimum green time in facilitating the safe and efficient movement of vehicles through an intersection. Minimum green time is designed to provide sufficient opportunity for vehicles to accelerate from a stop and enter the intersection safely. This allocation of time considers various factors, including the approach speed of vehicles and the overall traffic flow at the intersection.

By allowing vehicles adequate time to reach a speed where they can safely navigate through the intersection, minimum green time plays a crucial role in reducing the potential for accidents and improving overall traffic efficiency. This time is specifically calculated to account for vehicle response times, ensuring that when the traffic signal turns green, vehicles can proceed without undue delay or risk.

Other considerations, such as time for pedestrians to cross or for drivers to interpret signals, play roles in traffic signal design but are not the primary focus of the minimum green time. The provision of adequate acceleration time reinforces the objective of traffic signals to manage vehicle flow effectively while prioritizing safety.
