Wyoming Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Wyoming 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 Wyoming Department of Transportation 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 Wyoming.

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

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 3 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 4 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 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

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 7 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 8 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 9 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 10 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 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

When you transport passengers across state lines:

You must be at least 21 years old
You can be any age
You only need a state license
You need a CDL endorsement other than P

Correct. Federal interstate minimum age is 21. Drivers under 21 may operate intrastate (within their state) only.

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 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 15 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 16 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 17 of 20

When fueling a bus:

Generally without passengers aboard; follow carrier policy if passengers must remain
Always with passengers
Always with smokers
Only at high speed

Correct. Most carriers require passengers to deboard during fueling for safety. Follow company policy.

Question 18 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 19 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 20 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.

About the Wyoming 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 Wyoming Department of Transportation 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.
