On limited access highways and turnpikes, under what condition may an apparatus be driven against the normal flow of traffic?

• A. The road is open to traffic in the opposite direction
• B. Traffic is light in the area
• C. The road is closed for construction
• D. The road has been closed by police units

Answer: (D)

Driving against the normal flow on limited‑access highways is only allowed when police units have closed the road and direct you to use the opposite direction. This official directive is given to manage an incident or create a safe detour, so emergency responders can reach the scene or navigate around a blockage. If the road is simply open in the opposite direction, traffic is light, or construction is underway, you must follow normal traffic patterns unless police explicitly instruct otherwise. A road closed by police units represents the situation where such direction is legitimately provided, making it the correct condition for driving against the flow.
