When a railroad signal requires you to stop, where should you stop relative to the nearest rail?
A railroad crossing has an active red warning lamp on the approach-side US crossbuck assembly. The card says the warning lights are flashing. No car, stop line or stopping-distance mark is shown.
Correct answer: 15 to 50 feet from the nearest rail
Why
The required stopping zone provides clearance from the track while keeping the crossing and signals visible.
