What is the speed limit for controlled access highways?

1. 55 miles per hour

2. 60 miles per hour

3. 65 miles per hour

4. 70 miles per hour

The correct answer is: 65 miles per hour

The speed limit for controlled access highways is set at 65 miles per hour. This is designed to ensure a balance between safely accommodating high-speed travel and reducing the risk of accidents. Controlled access highways are typically designed for faster traffic flow with fewer intersections and a more streamlined vehicle movement, which allows for higher speed limits compared to regular city streets or residential areas. The rationale behind this limit includes the need for consistency in speed for vehicles traveling over long distances, as well as facilitating safe merging and lane changes. It's essential for drivers to understand and adhere to these speed limits to maintain safety and efficiency on these types of roads.
