Railroad Grade Crossings; Stopping Required: Exception for Railroad Grade Crossing Equipped With Active Warning Device Not in Activated State

FMCSA proposes to amend the regulations related to driving a commercial motor vehicle (CMV) at railroad grade crossings. Currently, drivers of certain CMVs (e.g., buses transporting passengers and CMVs transporting certain hazardous materials) are required to stop before crossing a railroad track unless an exception applies, such as when the crossing is controlled by a functioning highway traffic signal transmitting a green indication. The Agency proposes to add a similar exception for a railroad grade crossing equipped with an active warning device that is not in an activated state (e.g., flashing lights or crossing gates down, indicating the arrival of a train).
