If you see this road sign, what is a legal speed to drive?

The sign indicates both a maximum and minimum speed limit for a roadway. It specifies a maximum speed of 55 miles per hour (mph) and a minimum speed of 30 mph. This type of sign is used to regulate traffic flow by ensuring that vehicles do not exceed the upper speed limit or travel too slowly, which can help maintain a consistent and safe driving pace. The minimum speed limit helps prevent traffic congestion and maintains smooth flow, while the maximum speed limit ensures safety on the road.
