Answer: (B)

A posted speed limit of 55 mph signifies that drivers should not exceed this speed under optimal conditions. This regulation is established to promote safety on the road, ensuring that vehicles travel at a speed that is safe for the conditions present. While some might think it represents a minimum speed or an average speed, the primary purpose of a speed limit is to establish a maximum speed that drivers must adhere to in order to minimize accidents and enhance the overall safety of all road users. Such limits might vary under different conditions, such as adverse weather or heavy traffic, but the posted limit remains a benchmark for safe maximum speed.
