A posted speed limit of 55 mph means what?

• A. You cannot exceed 55 mph at any time
• B. You may drive 55 mph only under favorable circumstances
• C. You should always drive 55 mph
• D. There are no conditions affecting speed

Answer: (B)

The posted speed limit of 55 mph indicates that this speed is the maximum allowable speed under favorable conditions. This means that while you can legally drive at 55 mph, it is essential to consider environmental factors such as weather, road conditions, and traffic. If conditions are less than favorable—like during rain, fog, or heavy traffic—drivers are expected to adjust their speed accordingly and drive safely below the posted limit. Understanding this helps to promote safe driving practices, taking into account not just the numerical limit but also the overall situation on the road.
