Not for all commercial trucks and buses. Only for trucks if carrying certain placarded hazmat cargo (including placarded empty) or when carrying any quantity of chlorine.
For commercial buses (capable of seating 16 passengers or more), if carrying passengers they must stop 15 to 50 feet before the crossing and some states require opening the door and then closing it before proceeding.
All school buses must stop 15 to 50 feet before the crossing, shift into neutral, open the entrance door and driver's window, then close the entrance door, before proceeding. Some states exempt school buses if there are no passengers on board, and others require the safety stop regardless.
All commercial vehicle drivers must determine that there is no train closely approaching and then they can move the entire vehicle continuously across the tracks, and they must not shift gears until the entire vehicle is clear of the crossing.
There is some variance by state, but these are the most common regulations.
