What is the speed limit on an expressway?

• A. 55
• B. 70
• C. 45
• D. 15

Answer: (B)

Expressways are designed for higher-speed travel, so the legal maximum posted is higher than on local streets. The sign you’d see on an expressway typically allows about seventy miles per hour, which matches the best choice here. That speed helps keep traffic moving smoothly when road design, sight distance, and traffic density are favorable. The other speeds represent slower road types—fifty-five or forty-five are more common on certain highways or rural roads, and fifteen is for zones with heavy pedestrian or school-focused restrictions. Always drive at or below the posted limit and adjust for conditions like rain, construction, or heavy traffic.
