What is a common feature of rural highway design in Virginia?

In rural highway design in Virginia, one common feature is the increased stopping sight distance. This design principle helps ensure that drivers have adequate visibility to see and respond to potential hazards on the road, such as obstacles, vehicles, or changes in road conditions. Rural highways often have higher speeds and less traffic congestion than urban areas, making it essential for drivers to be able to see far enough ahead to make safe driving decisions.

Increased stopping sight distance allows drivers ample time to react when encountering unexpected situations, thus enhancing overall safety on these roadways. This feature is especially pertinent in rural areas where intersections might not be controlled by stop signs or traffic signals, and the likelihood of encountering slower-moving vehicles or wildlife is greater.

The other options may relate to highway design but do not capture the primary focus of safety and visibility as effectively as increased stopping sight distance does in rural settings.
