Without a green signal or traffic-control attendant, how far before a drawbridge must a bus stop?
Correct answer: B – At least 50 feet
The Vermont CDL manual instructs a bus driver to stop at least 50 feet before the draw when the bridge has no signal light or traffic-control attendant. Before crossing, the driver must verify that the draw is completely closed. With a green signal or an attendant controlling traffic, the driver may proceed after slowing and confirming that it is safe.
