Hawaii Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Hawaii 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 Hawaii Driver License Office 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 Hawaii.

Question 1 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 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

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 4 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 5 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 6 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 7 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 8 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 9 of 20

A "passenger vehicle" requiring a P endorsement is generally:

Any commercial vehicle
A vehicle designed to transport 16 or more people, including the driver
A vehicle that carries cargo
A school bus only

Correct. The P endorsement is required for any commercial motor vehicle designed to carry 16 or more passengers including the driver.

Question 10 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 11 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 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

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 14 of 20

A bus driver who picks up a passenger between scheduled stops:

Is permitted in all cases
Must follow the carrier's policy and applicable regulations — many companies prohibit unscheduled pickups
Should always accept
Should always refuse

Correct. Carrier policy and regulations govern unscheduled stops. Most companies prohibit them for safety and liability reasons.

Question 15 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 16 of 20

Most bus injuries during a trip happen because of:

Driver hitting another vehicle
Sudden stops, sharp turns, and quick lane changes throwing passengers
Engine failure
Fuel issues

Correct. Standing or unbelted passengers are vulnerable to abrupt motion. Smooth driving prevents most in-bus injuries.

Question 17 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 18 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 19 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 20 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.

About the Hawaii 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 Hawaii Driver License Office 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.
