Which situation warrants stopping before entering an intersection?

Stopping before entering an intersection is necessary when pedestrians are crossing. This is to ensure the safety of pedestrians who have the right of way. By stopping, drivers allow pedestrians to cross safely, fulfilling legal obligations and contributing to the overall safety of all road users. Pedestrian safety is a crucial consideration in traffic laws, and being vigilant for crossing pedestrians is essential for responsible driving.

In other scenarios, such as when traffic is backing up, it may be more about adjusting to the conditions of ongoing traffic. If there are no cars ahead, stopping may not be warranted since there is no imminent danger or requirement to pause. When the light is green, typically, vehicles are expected to proceed unless there are other specific obstacles, making stopping unnecessary in that context.
