At a level crossing, the same rules apply to trucks as do to cars, in that the Train always has the right of way. As long as there's no indication of a train coming, (lights flashing, etc) the truck does not have to stop.
However, some trucks, particularly those carrying dangerous goods, are required to stop regardless of whether or not the lights are flashing, to check to make sure there is in fact no train coming. If this is the case, there will be a sign on the back of the truck warning that it stops at all railroad crossings.

All vehicles must stop at all railroad crossings when lights are flashing or barriers are lowered. It is important to always follow the law and exercise caution at railroad crossings to ensure the safety of yourself and others.
Trains
Hazmat haulers are required to stop at railroad crossings - a food grade tanker would not. They only have to stop long enough to ensure there isn't a train coming.
If there is no stop line or crossing gate (which indicates where to stop), you are required to be not less than 15 feet from the nearest rail.
Bus
Buses and some other types of commercial vehicles are required to stop at all railroad crossings in order to make sure there is no train coming. This is true even at crossings that have been cut off and can no longer be approached by a train. When there is an Exempt sign at the crossing they are not required to stop. It happens often at tracks that are cut off or abandoned thus there will be no train to stop for.

When ever the red lights flash at railroad crossings you should stop at least 15 feet from the nearest rail. Flashing red lights at a railroad crossing are essentially the same as a red light at an intersection. You can be cited for not stopping in either situation. When it comes to railroad crossings it is much better to be safe than sorry. When a train hits a car the casualty rate to the occupants of the car is almost 100 percent.
Like I have said in a previous post about railroad crossings. Yes they do, any kind of vechicle has to stop at a railroad crossing. Would you want to get hit by a 50 mph train that will not be able to stop for over 1/2 mile. Go to http:/www.oli.org and look at Operation Lifesavers website. It will give you all the answers you would ever need.
