What is the purpose of a speed limit sign?

Answer: B — To inform drivers of the maximum allowable speed

The purpose of a speed limit sign is to inform drivers of the maximum allowable speed for a particular roadway. These signs are established based on various factors, including road conditions, traffic levels, and safety considerations. When drivers see a speed limit sign, it indicates the safest and legal maximum speed they are expected to adhere to in that area. By following this regulation, drivers help ensure their safety as well as that of other road users. While some might think speed limit signs serve as recommendations or advice for safe driving practices, they are legally enforceable limits that drivers must follow. This distinction is crucial for maintaining order on the roads and reducing the risk of accidents.
