A. Stopping At Crossing: Whenever any person driving a vehicle approaches a railroad grade crossing under any of the circumstances stated below, the driver of such vehicle shall stop within fifty feet (50') but not less than fifteen feet (15') from the nearest rail of such railroad, and shall not proceed until he can do so safely. The foregoing requirements shall apply when:
1. A clearly visible electric or mechanical signal device gives warning of the immediate approach of a railroad train.
2. A crossing gate is lowered or when a human flagman gives or continues to give a signal of the approach or passage of a railroad train.
3. A railroad train approaching within approximately one thousand five hundred feet (1,500') of the highway emits a signal audible from such distance and such railroad train, by reason of its speed or nearness to such crossing, is an immediate hazard.
4. An approaching railroad train is plainly visible and is in hazardous proximity to such crossing.
5. A railroad employee by signal indicates the approach of a railroad train. During the nighttime such signal shall include a lantern or other light.
No person shall drive any vehicle through, around or under any crossing gate or barrier at a railroad grade crossing while such gate or barrier is closed or is being opened or closed.
B. Obstructing Crossings: It shall be further unlawful for the directing officer or the operator of any railroad train to direct the operation of or to operate the same in such manner as to prevent the use of any street for purposes of travel for a period of time longer than five (5) minutes, except that this provision shall not apply to trains in motion other than those engaged in switching.
