What does a white speed limit sign indicate?

A white speed limit sign indicates the maximum speed limit allowed in that area. This regulation is crucial for maintaining safety on the road, as it informs drivers of the highest speed at which they may legally travel. Adhering to this limit helps prevent accidents and ensures that vehicles operate within a safe range, taking into consideration road conditions, traffic, and other factors.

The correct answer emphasizes the importance of speed limits in promoting road safety. These signs are placed strategically to ensure drivers are aware of the maximum allowable speed in different areas, especially in zones where conditions may change, such as schools, residential areas, or construction zones. Therefore, following this guidance promotes a safer driving environment for everyone.
