Why do some vehicles have to stop at railroad crossings?

There are some vehicles that have a sign on back that says it stops at all railroad crossings. They are usually buses. Why do they need to stop?

    Well.... most everybody is real close....

    All School Buses, regardless of size, or passenger load are required by federal law to stop no greater than 50 feet, but not closer than 15 feet to the nearest rail, open the door, look and listen for trains and then proceed with caution over the tracks without shifting the transmission (if it's a manual shift).

    Any "Placarded" (hazardous material signage) load in any size truck is required to do the same. (except for the opening of the door). This would include a pickup carrying something like compressed air tanks or oxygen tanks that require it to be placarded.

    There are a few exceptions to the rule.... if the railroad crossing is controled by a traffic signal, ( the track is running through an intersection that has a traffic light that controls all directions of road traffic) they do not have to stop. If it is marked "exempt" they also do not have to stop.

    I hope this helps....

    Source(s): The following link is from Pennsylvania and pretty much covers the rules and regulations for all states. It states only School Buses are required to stop. In Washington State, all buses are bound to this law. When in doubt... stop! http://members.aol.com/StatutesP1/75PA3342.html Personal experience... 30 years and 2.5 million miles in a truck.

    Safety is the primary concern. Safety for the passengers (like in a school bus), the driver of the large vehicle, and the people on the train who could be injured or killed if a collision resulted in a derailment. Another reason is that large vehicles will have to slow down for the bumps going across a railroad track or crossing. Since slowing down will normally require the use of a lower gear the larger vehicles would have a very difficult time accelerating to escape the tracks quickly if an approaching train suddenly came into view. Of course all of this results in regulations for some types of vehicles (buses, tankers, etc) and common sense for many others.

    Even if a YIELD sign or just a Crossbuck sign is posted at a highway-rail grade crossing, the Code of Federal Regulations (49 CFR 392.10) requires drivers of vehicles carrying passengers for hire, school buses carrying students, and vehicles carrying hazardous materials to stop before crossing the tracks.

    State or local laws or regulations establish which crossings may be posted as "exempt" from this requirement to stop except when a train, locomotive, or other railroad equipment is approaching or occupying the highway-rail grade crossing, or the driver's view is blocked.

    US Department of Transportation (DOT) safety rules require that all school buses and trucks carrying hazardous materials like LP gas or fuels must come to a full stop and check for approaching trains before crossing any level grade crossing.

    If they carry people or explosive materials it is a law. Some rail crossings are called no blow, which means the township or town requested no whistle be blown. Although it is up to the guy driving a few hundred thousand tons of train to use it in an emergency, there is a chance no whistle will be blown. All about safety.

    Most vehicles containing hazardous materials have to stop because if a train hits them, trouble in paradise, so to speak. School buses have to stop mostly because if that many children get hit by a train, their parents can be considered hazardous.

    Federal law. Any vehicle transporting passengers (like a bus) or carrying hazardous materials.
