Ohio Passenger CDL Practice Test

This is a free 20-question practice test for the Passenger portion of the Ohio 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 Ohio Bureau of Motor Vehicles 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 Ohio.

Question 1 of 20

Passenger fatalities are most often caused by:

Single-vehicle rollovers and collisions; speed and seat belts (where required) are common factors
Mechanical failure
Bad weather only
Cargo

Correct. Single-vehicle rollover and head-on/angle collisions account for most passenger fatalities. Speed control and where applicable, seatbelt use, reduce risk.

Question 2 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 3 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 4 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 5 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.

Question 6 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 7 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 8 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 9 of 20

When carrying medical or fragile cargo with passengers (e.g., lab specimens):

Only allowed when small quantity, packaged correctly, and stored in baggage area
Allowed in any quantity
Allowed in the cab
Always prohibited

Correct. Some emergency medical and lab shipments are allowed under tight conditions: small quantity, proper packaging, baggage-area storage, with carrier approval.

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

Where must hazardous materials that are allowed on a bus be carried?

Inside the passenger area
Only in the baggage compartment, never in the passenger area
On the dashboard
In the cab with the driver

Correct. When allowed at all, the small quantities of hazmat permitted on buses must be in the baggage compartment, separated from passengers.

Question 12 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 13 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 14 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 15 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 16 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 17 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 18 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 19 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 20 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.

About the Ohio 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 Ohio Bureau 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.
