Safe DrivingCâu 48 / 120
Why should you never start across a railroad crossing unless you are certain you can clear it completely?
a.Because crossing gates close automatically after 10 seconds
b.Because state law requires a permit
c.Because the crossing surface damages tires
d.Because a long, heavy vehicle can become trapped on the tracks with no room to move forward or back
Giải thích
Traffic backed up on the far side can leave a long vehicle stopped on the rails with nowhere to go, so you must have room on the other side before you start. Gates do not operate on a fixed 10-second timer, no permit is required for a normal crossing, and tire damage is not the reason for the rule.
