How do highways differ from expressways?

Answer: B — Highways may have varying degrees of access control, expressways are for high-speed traffic with limited access

Highways and expressways serve different purposes and have distinct characteristics related to access control and traffic flow. Highways are broader categories that encompass various types of roads, including those that may have multiple access points, such as intersections and traffic signals. They can accommodate a mix of lower-speed traffic, including local vehicles, commercial traffic, and agricultural vehicles, and may not always prioritize high-speed travel. On the other hand, expressways are specifically designed for high-speed travel. They feature limited access points, which means that vehicles can only enter or exit at designated ramps. This design minimizes interruptions from stop signs, traffic signals, and pedestrian crossings, allowing for a smoother and faster flow of traffic. Expressways focus on maintaining higher speeds, reducing delays, and enhancing safety by keeping potential conflicts with local traffic to a minimum. This distinction makes the correct answer clear because it emphasizes that while highways can vary in their level of access control, expressways are specifically meant for high-speed travel and are characterized by having limited access.
