At a railroad grade crossing without an applicable exception, what must a driver of a vehicle carrying cargo that requires a hazardous-material placard do?

Correct answer: C – Stop before crossing the tracks
Under Wyoming law, a driver transporting cargo that requires a U.S. Department of Transportation placard must generally stop between 15 and 50 feet from the nearest rail. The driver must look and listen for rail traffic and proceed only when safe. Exceptions include certain crossings controlled by an officer, traffic signal, gates, flashing-light signal, or an official exemption sign.
