What separates opposing traffic on a divided highway?

• A. A stop sign
• B. A physical obstruction
• C. Traffic signals
• D. Road markings

Answer: (B)

On a divided highway, a physical obstruction is what separates opposing traffic. This obstruction can be barriers, medians, or any construction designed to keep vehicles traveling in opposite directions from crossing into each other’s lanes. The purpose is to enhance safety by minimizing the chances of head-on collisions and helping to maintain orderly traffic flow. While other choices such as stop signs, traffic signals, and road markings play roles in traffic management and control, they do not provide a physical separation of opposing lanes. Stop signs and traffic signals help manage when vehicles can or cannot proceed, while road markings guide lane usage and directions but do not physically block traffic from crossing into opposing lanes. Thus, a physical obstruction is the most effective and appropriate means to ensure the safety and separation of traffic on divided highways.
