What does a speed bump indicate to drivers?

A speed bump serves as a visual and physical cue for drivers, indicating that a reduction in speed is necessary as they approach the area. These bumps are typically installed in locations where slower speeds are essential for safety, such as near schools, playgrounds, or areas with high pedestrian traffic. They help to reduce vehicle speed and encourage drivers to be more cautious.

While one might be tempted to think of other interpretations for the other options, they do not align with the primary purpose of a speed bump. Specifically, a speed bump does not indicate a parking area or suggest that normal speeds can be maintained. Instead, it directly prompts drivers to slow down, making safety a priority in potentially hazardous zones.
