When are pedestrians allowed to cross the road at a red signal?

Pedestrians are allowed to cross the road at a red signal when a green pedestrian signal is displayed or at a crosswalk when permitted because these indicators are specifically designed to ensure pedestrian safety. The green pedestrian signal provides clear instructions that it is safe for pedestrians to proceed, helping to coordinate pedestrian movement with vehicle traffic at intersections.

Crosswalks are designated areas marked for pedestrian use, and traffic signals or signs give the right of way to pedestrians in these zones. This organized approach minimizes the risk of accidents and ensures that both drivers and pedestrians understand when it's safe to move.

The other responses do not adhere to the established traffic laws regarding pedestrian movement. Crossing only when no cars are coming could lead to unpredictable situations, as it may not consider the traffic signals. Walking whenever pedestrians feel it is safe undermines the structured system meant to protect them. Finally, waiting only for police instructions may not be practical since police may not always be present at intersections to direct traffic.
