What is the speed limit on two-lane, undivided highways?

The speed limit on two-lane, undivided highways is set at 55 miles per hour. This regulation is in place to promote safety and reduce the likelihood of accidents on these types of roads, which often present more challenges compared to multi-lane highways.

Two-lane, undivided highways typically have a higher risk for head-on collisions, as vehicles traveling in opposite directions share the same roadway without a physical barrier. A speed limit of 55 mph allows drivers to maintain a reasonable speed while allowing for greater reaction time to hazards, such as passing vehicles or obstacles on the road.

Setting the speed limit at 55 mph on these highways helps to balance the need for efficient travel with the necessity of maintaining safety in potentially hazardous conditions where visibility may be limited and road conditions may change. Understanding the rationale behind this speed limit is important for promoting safe driving habits and making informed decisions on the road.
