A speed limit sign indicates the maximum speed allowed on that road. The purpose of this sign is to inform drivers of the legal speed limit, which is set to enhance road safety and improve traffic flow. Adhering to the indicated speed limit helps to minimize the risk of accidents, as driving too fast can reduce reaction times and increase the severity of potential collisions.

Speed limits take into consideration various factors such as road conditions, traffic density, and the type of area (urban, rural, etc.) to ensure that all road users can travel safely. It's important to note that while it is legal to drive at or below the speed limit, exceeding it is against the law and can result in penalties.

The other options refer to different aspects of road regulations but do not accurately define the purpose of a speed limit sign. For instance, minimum speeds are set for certain types of roads, typically indicated by different signage, and speed recommendations during adverse weather conditions are not legally enforceable like speed limits are.
