Never get any closer than 15 feet when a train is passing through a railroad crossing.
Explanation:
According to the norms set by the motor laws, it is mandatory for an individual to stop at least 15 feet away from the railroad crossing to avoid the possibility of any kind of hazardous accident.
No matter whether the person that has come across a railroad crossing is on his feet, on a bike, or in a car, he is supposed to follow the norm and stop 15 feet away or possibly more than that from the railroad crossing.
