Question 1 of 20

When backing a bus, you should:

Sound the horn before moving and use a helper outside the bus when available
Back without warning
Back only at night
Back only with passengers

Correct. Sound the horn before backing. Use a helper to guide whenever possible — bus blind spots are large.

Question 2 of 20

When approaching a school bus that has its red flashing lights on:

Stop and wait until the lights are turned off and the school bus moves
Pass on the left
Pass on the right
Continue at speed

Correct. When a school bus is loading or unloading children with red flashers on, all approaching vehicles (with limited exceptions for divided highways) must stop.

Question 3 of 20

When you are about to leave a stop with passengers aboard, you should:

Confirm doors are closed, mirror-check for late-boarding passengers and pedestrians, then proceed slowly
Move quickly
Use only the trailer brake
Skip the mirror check

Correct. Doors closed, mirrors check, slow gentle start. Late-boarders and pedestrians are common at busy stops.

Question 4 of 20

Which of the following is part of the bus pre-trip inspection?

Passenger seat condition, emergency exits, signaling devices, kneeling mechanism, wheelchair lift if equipped
Only the engine
Only the brakes
Only the lights

Correct. Bus inspection includes all standard items plus passenger-area items: seats, emergency exits, signaling devices, kneeling/lift equipment, fire extinguisher.

Question 5 of 20

When stopping at a railroad crossing, the bus must stop:

On the rails
Between 15 and 50 feet from the nearest rail
Anywhere within 100 feet
Only if a train is heard

Correct. Stop 15 to 50 feet from the nearest rail. Look both ways and listen before proceeding.

Question 6 of 20

When approaching a stop where passengers will board, you should:

Slow gradually, signal, stop at the curb, set the parking brake, open the door
Stop suddenly
Drive past
Honk the horn

Correct. Plan the stop, signal, decelerate smoothly, stop at the curb, set the parking brake before opening the door — interlock should prevent door opening unless brake is set.

Question 7 of 20

A driver may transport ___, in addition to passengers, if the carrier permits:

Express small parcels under most circumstances; the carrier sets policy
Live explosives
Tear gas
Class 7 radioactives without limit

Correct. Many bus operators permit small express packages under company policy. The hazmat rules above still apply.

Question 8 of 20

You discover an emergency exit that does not function. You should:

Carry passengers anyway
Place the bus out of service until the exit is repaired
Tape it shut
Ignore it

Correct. A non-functional emergency exit puts passengers at risk. The bus is out of service until repaired.

Question 9 of 20

After every trip, the bus driver should:

Walk through the bus to check for sleeping passengers, lost items, damage
Lock the doors and leave
Only check the driver area
Skip the inspection

Correct. Always do a post-trip walkthrough — check every seat for sleeping passengers, lost items, and damage. Many news-worthy incidents involve passengers left aboard.

Question 10 of 20

Looking out for passengers boarding through the front door:

Watch for elderly, mobility-limited passengers and those with strollers; offer the kneeling feature if equipped
Rush them
Only watch for adults
Ignore them

Correct. Use the kneeling mechanism, lift, or ramp as needed. Allow time for safe boarding.

Question 11 of 20

On highway travel:

Maintain steady speed, avoid abrupt lane changes, signal early
Accelerate hard
Tailgate
Lane-weave to make time

Correct. Smooth, predictable driving keeps passengers comfortable and safe.

Question 12 of 20

A bus driver should:

Refuse boarding to obviously intoxicated passengers if they pose a danger
Carry any passenger
Carry only adults
Only carry seated passengers

Correct. Carriers may refuse boarding for safety reasons (intoxication, weapons, threatening behavior). Document and report such refusals.

Question 13 of 20

Discharging passengers should be done:

Only at safe locations — paved curb, off the road, away from traffic
Anywhere
In the middle of an intersection
Only on highways

Correct. Stop at designated stops or safe pull-offs. Never discharge into a travel lane.

Question 14 of 20

After a trip, you should leave the bus:

Clean and ready for the next driver
Untouched
With trash everywhere
With doors open

Correct. Sweep, check for lost items, secure the bus, and complete the post-trip inspection report.

Question 15 of 20

Buses transporting children on field trips:

Follow standard bus rules unless they are school buses, which have additional rules
Are unregulated
Have no inspection
Have no driver requirements

Correct. School buses have stricter rules including the S endorsement. A motorcoach used for a field trip follows the standard P rules.

Question 16 of 20

When approaching a drawbridge, a bus must:

Stop at least 50 feet before the draw — unless there is a traffic light or attendant — and proceed only when you can do so safely
Cross at full speed
Honk the horn
Reverse

Correct. Stop at least 50 feet before any drawbridge. The exception is if there is a traffic-signal light or an attendant directing traffic, or the bridge has been closed and locked.

Question 17 of 20

When you stop a bus, you should:

Stop smoothly to avoid throwing standing passengers off-balance
Stop suddenly
Use only the parking brake
Stop on a hill always

Correct. Smooth stops protect standing passengers and reduce surge for seated ones. Plan stops in advance.

Question 18 of 20

Stops requiring extra caution:

School zones, construction zones, intersections, slick roads
None of the above
Empty highways
Long straightaways

Correct. Anywhere with pedestrians, reduced visibility, or reduced control demands extra attention.

Question 19 of 20

When approaching a school bus on the same side of the road with red lights flashing:

Stop
Pass slowly
Pass quickly
Honk the horn

Correct. Drivers (including bus drivers) approaching a school bus loading or unloading children must stop until red lights are off and the bus moves.

Question 20 of 20

A bus driver in heavy fog should:

Reduce speed substantially, use low beams, avoid sudden stops
Speed up to clear it
Use high beams
Tailgate

Correct. Same fog rules as any vehicle: low beams, slow speed, gentle inputs, four-way flashers if moving slowly.

About the Connecticut Passenger exam

Most states administer 20 Passenger questions and require 80% to pass. The exam covers passenger safety, vehicle inspection, loading and unloading, prohibited cargo, emergency exits, and conduct expected of a passenger-vehicle operator. A separate skills test in a representative passenger vehicle is also required.

The Connecticut Department of Motor Vehicles follows the federal CDL standards established by FMCSA. To earn the Passenger credential, you must answer at least 80% of the questions correctly. Many candidates score lower the first time because the test pulls from a large pool — refreshing this page will give you a different mix of questions, drawn from the same authoritative source.
