Arizona Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Arizona 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 Arizona Motor Vehicle Division 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 Arizona.

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

A passenger vehicle drove with people standing forward of the standee line. This is:

Acceptable
Prohibited — standees may not be forward of the line while the vehicle is in motion
Required
Encouraged

Correct. Standees forward of the line are at risk in emergency stops or sudden braking. Enforce the line.

Question 3 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 4 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 5 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 6 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 7 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 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

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 10 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 11 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 12 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 13 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.

Question 14 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 15 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 16 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 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

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 19 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 20 of 20

A bus driver may carry, in the baggage compartment, certain hazardous materials in small quantities except:

Class 1 explosives (other than small arms), Division 6.1 PIH, Class 7 radioactives above limited quantities, and tear gas
Letters and parcels
Personal luggage
Driver's tools

Correct. Strict prohibitions for buses include Class 1 explosives (other than small-arms ammunition), Division 6.1 PIH, most Class 7 radioactives, and tear gas.

About the Arizona 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 Arizona Motor Vehicle Division 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.
