Safe DrivingCâu 47 / 120
You are driving a placarded hazardous materials load and approach an unguarded railroad crossing. What must you do?
a.Proceed without stopping if no train is visible
b.Sound the horn and cross at normal speed
c.Stop no closer than 15 feet and no farther than 50 feet from the nearest rail, look and listen, then cross without shifting gears
d.Stop directly on the first rail to get the best view
Giải thích
Placarded hazmat vehicles, most buses, and cargo tanks must stop between 15 and 50 feet from the nearest rail, check both directions, and cross in a gear that will not require shifting. Rolling through, relying on the horn, or stopping on the tracks all defeat the purpose of the required stop.
