Question 1 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

Question 2 of 20

A bus driver must never:

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

Question 3 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

Stop and wait until the lights are turned off and the school bus moves
Pass on the left
Pass on the right
Continue at speed

Correct. When a school bus is loading or unloading children with red flashers on, all approaching vehicles (with limited exceptions for divided highways) must stop.

Question 5 of 20

When a bus has standees, the driver should:

Drive smoothly, accelerate and brake gently, take corners with care
Drive aggressively
Brake hard at every stop
Ignore standees

Correct. Standees can fall in any sudden movement. Drive smoothly to keep them safe.

Question 6 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 7 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 8 of 20

Looking out for passengers boarding through the front door:

Watch for elderly, mobility-limited passengers and those with strollers; offer the kneeling feature if equipped
Rush them
Only watch for adults
Ignore them

Correct. Use the kneeling mechanism, lift, or ramp as needed. Allow time for safe boarding.

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

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

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 12 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 13 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 14 of 20

When approaching a school bus on the same side of the road with red lights flashing:

Stop
Pass slowly
Pass quickly
Honk the horn

Correct. Drivers (including bus drivers) approaching a school bus loading or unloading children must stop until red lights are off and the bus moves.

Question 15 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

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

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 19 of 20

Buses transporting children on field trips:

Follow standard bus rules unless they are school buses, which have additional rules
Are unregulated
Have no inspection
Have no driver requirements

Correct. School buses have stricter rules including the S endorsement. A motorcoach used for a field trip follows the standard P rules.

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.

About the Colorado 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 Colorado Division 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.
