What is the speed limit for two-lane roads?

Answer: C — 55 miles per hour

The designated speed limit for two-lane roads is 55 miles per hour. This limit is established to promote safety and efficiency on roads that typically have less traffic than highways but still require drivers to maintain a consistent speed. Two-lane roads often feature intersections, residential areas, and varying conditions that necessitate a balance between mobility and caution. Setting the speed limit at 55 miles per hour helps ensure that drivers can react appropriately to changing conditions, including potential hazards such as pedestrians, cyclists, and other vehicles entering or crossing the road.
