Massachusetts Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Massachusetts Commercial Driver's License knowledge exam. Questions are pulled from a pool of 58 drawn from the AAMVA CDL Manual, which is the source document the Massachusetts Registry of Motor Vehicles uses to write its actual exam.

How it works: Click an answer. The correct choice highlights in green, and you'll see a short explanation. Aim for 85% or better before you sit for the real test in Massachusetts.

Question 1 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 2 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 3 of 20

A bus driver who is convicted of using the bus to commit a felony or driving under the influence with passengers aboard faces:

No penalty
Permanent disqualification or extended disqualification
A fine only
A warning

Correct. Federal rule: certain offenses (using the CMV in a felony, DUI with passengers) bring extended or permanent disqualification.

Question 4 of 20

Bus emergency exits must be:

Operable, clearly marked, and unobstructed
Locked
Hidden
Optional

Correct. Emergency exits must be operable, clearly identified, and never blocked by cargo or passengers.

Question 5 of 20

Bus drivers must check:

Brake condition before every shift
Only annually
Only when problems are noticed
Only at the dealership

Correct. Pre-trip inspection — including brake condition — is required before every shift, regardless of how recently the bus was driven.

Question 6 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 7 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 8 of 20

On a bus with a wheelchair lift, you should:

Verify the lift is operating and stowed correctly during pre-trip
Ignore it
Operate it only after passengers complain
Skip the lift

Correct. Test lift operation during pre-trip; verify it stows correctly so it does not interfere with door operation or hit cars during the route.

Question 9 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 10 of 20

Maximum passenger capacity is determined by:

Vehicle manufacturer's rating and seating configuration
The driver's preference
The weather
The route

Correct. Manufacturer rating + seating config = maximum allowed passengers. Standees (where allowed) are capped by the standee-line capacity.

Question 11 of 20

Bus brake systems require:

The same federal pre-trip air-system check as other commercial vehicles, with attention to bus-specific items (door interlocks, retarders if equipped)
No special check
Hydraulic checks only
Only the parking brake

Correct. Standard air-system check applies. Bus-specific: door safety interlock (door open = vehicle can't move), retarder/exhaust brake operation if equipped.

Question 12 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 13 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 14 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 15 of 20

You may NOT carry which of the following on a passenger bus?

Small-arms ammunition, hospital supplies in emergency
Class 2.3 (poison gas) or Class 7 (radioactive) above small quantities, tear gas, explosives other than small arms ammunition
Driver's personal luggage
Mail

Correct. Buses cannot carry Class 2.3 poison gases, most Class 7 radioactive materials, tear gas, or most Class 1 explosives. Small-arms ammunition and certain emergency shipments may be allowed.

Question 16 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 17 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 18 of 20

When carrying live animals (where allowed):

Comply with carrier rules; many carriers permit only service animals in the passenger area
Always allowed in any class
Always prohibited
Only at night

Correct. Service animals are required by ADA. Other animals depend on carrier policy and applicable regulations.

Question 19 of 20

Speed control on a long downgrade in a bus is critical because:

Brake fade can occur, and braking distance grows quickly with passenger load
Speed is irrelevant
Buses cannot go downhill
Speed is the same as a car

Correct. Heavy passenger load + long downgrade = brake fade risk. Select a lower gear before starting down and use intermittent firm braking.

Question 20 of 20

Buses must stop at every railroad crossing:

Yes, with limited exceptions (industrial switching tracks in city traffic, abandoned tracks, streetcar tracks)
No, never
Only at night
Only if a train is in sight

Correct. Buses, school buses, and placarded hazmat vehicles must stop at every railroad crossing 15 to 50 feet from the nearest rail, with narrow exceptions.

About the Massachusetts 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 Massachusetts Registry 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.
