Question 1 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 2 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 3 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 4 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 5 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 6 of 20

You should report any safety concerns about the bus:

Immediately to the carrier — never delay
Only at the end of the day
Only weekly
Never

Correct. Report safety issues immediately. Document with the daily driver vehicle inspection report (DVIR).

Question 7 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 8 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 9 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 10 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 11 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 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

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 14 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.

Operable, clearly marked, and unobstructed
Locked
Hidden
Optional

Correct. Emergency exits must be operable, clearly identified, and never blocked by cargo or passengers.

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

When carrying live animals (where allowed):

Comply with carrier rules; many carriers permit only service animals in the passenger area
Always allowed in any class
Always prohibited
Only at night

Correct. Service animals are required by ADA. Other animals depend on carrier policy and applicable regulations.

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

About the Delaware 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 Delaware 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.
