Under horn failure at a crossing, which condition could exempt you from continuing on-ground warning after stopping?

• A. No traffic is approaching or stopped at the crossing not equipped with automatic crossing warning devices.
• B. The crossing has a flagger present.
• C. The train is in emergency mode.
• D. A detour signal directs to proceed.

Answer: (A)

When a horn fails at a crossing, you must still protect the crossing and make a judgment about continuing to warn road traffic. The situation that allows you to skip continuing on-ground warning after stopping is when there’s no road traffic approaching or stopped at the crossing and the crossing itself does not have automatic warning devices. In that scenario, there’s no one to warn and no automatic system to rely on, so continuing manual warnings isn’t necessary. If there is any traffic approaching or at the crossing, or if the crossing has automatic warning devices, you would remain responsible for protecting the crossing and continuing appropriate warnings until it’s safe to proceed.
