At a railroad crossing, flashing red warning lights require you to:
Correct answer: C – Stop 15 to 50 feet from the nearest rail and wait for the warning to end
Utah law requires a driver to stop between 15 and 50 feet from the nearest rail when a crossing signal warns of an approaching train or other on-track equipment. Normally, remain stopped until the lights stop flashing and any gate is fully raised. A narrow exception applies to a suspected malfunction at a crossing without a gate, but only after all statutory safety conditions are met.
