Certain vehicles, particularly those transporting passengers, are mandated to halt at railroad crossings before proceeding. This safety measure is a preemptive action designed to mitigate the risk of collisions with trains. It involves stopping a safe distance from the tracks, visually surveying for approaching trains in both directions, and listening for any audible signals before carefully crossing.
The practice stems from a history of preventable accidents where buses and other large vehicles were struck by trains. Implementing mandatory stops at crossings significantly reduces the likelihood of such incidents by forcing drivers to actively assess the situation and confirm that the crossing is safe. This regulation protects not only the passengers aboard the bus but also the general public and the occupants of the train.
