At an intersection, if you cannot account for all lanes of traffic, you should:

• A. Cautiously proceed through the intersection because the warning devices and emergency situation give the apparatus the right of way
• B. Stop, check the lanes of traffic, then proceed
• C. Use the air horn and proceed without stopping
• D. Move to the left lane and accelerate

Answer: (B)

When you can’t account for all lanes at an intersection, the safe move is to stop and verify there’s a clear path in every direction before proceeding. This is about preventing collisions with vehicles that may be hidden from view in blind spots or in other lanes. Even with warning devices and emergency status, you don’t automatically have the right of way; drivers in other lanes may not yield, or you may miss someone entering the intersection from a side street. By stopping, scanning for traffic across all lanes, and proceeding only when you’ve confirmed a safe gap, you reduce the risk of hitting another vehicle. The other options can lead to crashes because they assume visibility or priority that isn’t guaranteed.
