What does a speed limit sign communicate?

A speed limit sign primarily indicates the maximum speed that drivers are legally permitted to travel on a particular section of roadway. This regulation is put in place to maintain safety for all road users, as speeding can significantly increase the risk of accidents. The speed limit is determined based on various factors, such as road conditions, traffic patterns, and the surrounding environment.

Understanding the maximum speed is crucial for drivers to comply with laws and ensure safe driving practices. By adhering to these signs, drivers can better respond to changing conditions on the road and help prevent accidents. Other options may suggest different speed-related concepts, but they do not accurately describe the function of a speed limit sign.
