Tennessee Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Tennessee 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 Tennessee Department of Safety and Homeland Security Driver Services 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 Tennessee.

Question 1 of 20

After accepting passengers, the driver should:

Verify all are seated or behind the standee line, doors closed, parking brake released, then proceed
Move immediately
Wait until all are standing
Use only the trailer brake

Correct. Verify safety: all seated or behind line, doors closed, brake released, then proceed.

Question 2 of 20

The "standee line" on a bus marks:

Where standees may not pass while the bus is in motion (typically 2 feet behind the driver)
The middle aisle
The rear emergency exit
The fuel-fill location

Correct. On buses with a standee line, passengers may not stand forward of the line while the bus is moving. The line keeps standees clear of the driver and exit doors.

Question 3 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.

Question 4 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.

Question 5 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 6 of 20

Where must hazardous materials that are allowed on a bus be carried?

Inside the passenger area
Only in the baggage compartment, never in the passenger area
On the dashboard
In the cab with the driver

Correct. When allowed at all, the small quantities of hazmat permitted on buses must be in the baggage compartment, separated from passengers.

Question 7 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 8 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 9 of 20

Carry-on baggage on a bus may be:

Stored anywhere
Stored in overhead racks or under seats — never blocking aisles or emergency exits
Stored in the aisle
Held in your lap

Correct. Carry-on must not block the aisle, the emergency exit, or the doorway. Use overhead racks or under-seat space.

Question 10 of 20

A bus that has been in an accident:

Should be inspected before continuing in service
Can continue immediately
Is fine if no passengers complain
Does not require inspection

Correct. Post-accident inspection is required by carrier policy and federal rules. Damage to brakes, suspension, or structure may not be visible without inspection.

Question 11 of 20

When a passenger is disorderly:

Pull over at a safe location, follow the carrier's procedure, request assistance from law enforcement if needed
Argue with them
Speed up
Drive faster

Correct. Driver safety first: pull off safely, follow company policy, request help from authorities if the situation warrants.

Question 12 of 20

When carrying medical or fragile cargo with passengers (e.g., lab specimens):

Only allowed when small quantity, packaged correctly, and stored in baggage area
Allowed in any quantity
Allowed in the cab
Always prohibited

Correct. Some emergency medical and lab shipments are allowed under tight conditions: small quantity, proper packaging, baggage-area storage, with carrier approval.

Question 13 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 14 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 15 of 20

Driver fatigue on a bus operation:

Is a major cause of bus crashes; HOS rules apply, plus carrier policies
Is no concern
Affects only night drivers
Is the same as a car driver

Correct. Bus operators have demanding schedules. HOS rules and carrier policy combine to manage fatigue. Sleep before driving.

Question 16 of 20

Driving a bus on slick roads requires:

Lower speed, longer following distance, and gentler steering and braking
Higher speed
Same speed as a car
Only the trailer brake

Correct. Reduce speed, increase following distance, and treat all inputs as if a passenger is standing — they may be.

Question 17 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 18 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 19 of 20

A bus driver must never:

Refuse to allow standees forward of the standee line
Use turn signals
Honk the horn
Wear a uniform

Correct. You should always enforce the standee line and prohibit standing or sitting in stairwells where they could be ejected in an emergency stop.

Question 20 of 20

A passenger bus driver who must operate over the bridge or in the tunnel:

Must respect any posted height, weight, and route restrictions
Can ignore signs
Drives faster
Reroutes through tunnels always

Correct. Verify posted weight, height, and routing restrictions. Bus routes may require pre-planning to avoid prohibited corridors.

About the Tennessee 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 Tennessee Department of Safety and Homeland Security Driver Services 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.
