Which sign might indicate a speed limit?

A speed limit sign is classified as a regulatory sign. Regulatory signs are used to inform drivers of the laws that they must obey while driving on the road. These signs typically give specific instructions or indicate prohibitions, including speed limits, yielding, stopping, and other important traffic regulations.

The nature of regulatory signs is to ensure compliance for the safety of all road users; therefore, they often emphasize rules that need to be followed, such as speed limits that are set based on the road type, traffic conditions, and surrounding environment. Understanding the role of regulatory signs is crucial for drivers to ensure they follow traffic laws and maintain safe driving habits.
