Nevada CDL — General Knowledge: Right-of-Way Practice Test

Question 1

You believe the signals at a railroad crossing are malfunctioning, and no police officer is there. What should a school bus driver do?

Accepted Answer

Call the dispatcher, report it, and ask how to proceed — If an officer is at the crossing, follow the officer's directions. If not, and the signal seems faulty, call your dispatcher to report it and get instructions.

Answer

Cross at normal speed since the signals are unreliable

Answer

Wait for a train to pass to test the signal

Answer

Turn around and skip the rest of the route

Question 2

Your school bus has started across the tracks when the crossing gate begins to come down. What should you do?

Accepted Answer

Keep driving across, even if the bus breaks the gate — Once you have started across, keep going until you've cleared the tracks, even if it means breaking the gate.

Answer

Stop on the tracks and wait for the gate to rise

Answer

Back up off the tracks

Answer

Stop and open the service door

Question 3

A train has passed a gated crossing, but the gate stays down. What should a school bus driver do?

Accepted Answer

Stay put and call the dispatcher rather than driving around the gate — If the gate is still down after the train has gone by, don't go around it. Call your dispatcher instead.

Answer

Drive carefully around the gate

Answer

Back up and use another crossing without reporting it

Answer

Have a student lift the gate

Question 4

You drive a bus toward a drawbridge that has no signal light and no traffic attendant. Where should you stop?

Accepted Answer

At least 50 feet short of the bridge's draw — Where a drawbridge has no signal light or traffic attendant, stop 50 feet or more ahead of the draw and confirm it is fully closed before you cross.

Answer

At least 15 feet before the draw

Answer

Right at the edge of the draw

Answer

No stop is needed if the bridge looks closed

Question 5

What kind of crash does the manual say school and transit buses sometimes have when pulling away from a bus stop?

Accepted Answer

Scraping off mirrors or hitting passing vehicles — Buses leaving stops sometimes scrape off mirrors or strike vehicles going by. Keep the bus's clearance in mind and look out for poles and tree limbs near stops.

Answer

Rear-ending the vehicle in front

Answer

Running over the curb at the stop

Answer

Rolling backward into the bus behind

Question 6

Your empty cargo tank last carried a hazardous material. Must you stop at railroad crossings?

Accepted Answer

Yes, cargo tanks used for hazmat must stop whether loaded or empty — Placarded vehicles, vehicles with any chlorine aboard, and vehicles with cargo tanks used for hazmat (loaded or empty) must all stop between 15 and 50 feet from the nearest rail.

Answer

No, only loaded tanks must stop

Answer

Only if the tank is placarded for explosives

Answer

Only at crossings with gates

Question 7

A school bus is approaching a crossing with several sets of tracks. Where should it stop?

Accepted Answer

Only before the first set of tracks — Where there are several tracks, the stop is made only before the first set. When you're sure no train is coming on any of them, cross them all without stopping.

Answer

Before each set of tracks

Answer

Between the first and second sets

Answer

Past the last set of tracks

Question 8

Your school bus is stopped with the red lights flashing and the stop arm out. What should you do before fully opening the door and signaling students to come?

Accepted Answer

Make a final check that all traffic has stopped — Turn on the red lights once traffic is a safe distance away and the stop arm is out, then confirm every vehicle has stopped before you open the door all the way.

Answer

Turn off the red lights

Answer

Release the parking brake

Answer

Honk to call the students over

Question 9

There is a stop sign just past a railroad crossing on your school bus route. How do you judge whether the bus has enough room on the far side?

Accepted Answer

Make sure the space beyond the tracks is at least the bus length plus 15 feet — Know the containment (storage) area at each crossing on your route. To size it, take the bus length and add 15 feet; if the bus won't fit, don't commit.

Answer

Make sure the space equals half the bus length

Answer

Assume any space will do since traffic will move

Answer

Stop on the tracks if needed, as long as the signals are quiet

Question 10

According to the manual, where do bus accidents often happen?

Accepted Answer

At intersections, even ones where a signal or stop sign governs the other traffic — Intersections are a common site of bus accidents, so stay cautious even when a signal or stop sign is controlling the other traffic.

Answer

On straight, empty highways

Answer

Inside bus depots

Answer

Only on freeway on-ramps

Question 11

You are driving a bus and signal to pull out from a stop into traffic. What should you assume about other drivers?

Accepted Answer

They may not brake to make room, so wait for a gap that fits your bus — Know how big a gap the bus needs to speed up and merge, wait for that gap, and never count on other drivers braking to let you in.

Answer

They must yield once your signal is on

Answer

They will stop if you flash your headlights

Answer

They will let you in if you start moving slowly

Question 12

A bus driver would normally stop before railroad tracks. At which of these may the driver slow down and check carefully instead of stopping?

Accepted Answer

A crossing marked 'exempt' — A bus may skip the stop, though it must still slow down and watch carefully for other traffic, at streetcar crossings, where a police officer or flagman is directing traffic, where the traffic signal is green, and at crossings marked 'exempt' or 'abandoned.'

Answer

A passive crossing with only a crossbuck

Answer

A crossing where the red lights are flashing

Answer

A crossing with two or more tracks
