Chauffeur License Test: Questions and Answers

Chauffeur license test questions are multiple choice and pull from a consistent set of topics: traffic rules and defensive driving, pre-trip vehicle inspection, warning devices for a disabled vehicle, air brakes if your vehicle has them, passenger loading and emergency procedures, ADA obligations toward riders with disabilities, and federal hours-of-service limits. The passing score is 80 percent on each section. What you won’t know until you check with your state is exactly how long your test runs, because “chauffeur license” can mean either a state-issued for-hire credential with a shorter exam or a full Commercial Driver’s License with a passenger endorsement.

Which Test You’re Actually Taking

There is no single federal credential called a chauffeur license. Some states still issue a license by that name; others fold the same authority into a for-hire endorsement on a standard driver’s license. The vehicle decides which test applies. If it’s designed to carry 16 or more people including you, or has a gross vehicle weight rating above 26,001 pounds, federal law requires a CDL rather than a state chauffeur credential.¹ Vehicles carrying 8 to 15 passengers with a GVWR between 10,000 and 26,000 pounds fall under what the federal government calls an Operator’s License category.²

CDL applicants take a general knowledge exam of roughly 50 questions plus a separate 20-to-25-question passenger endorsement test, and an air brake section if the vehicle has air brakes. State chauffeur or for-hire endorsement tests are usually shorter, often 20 to 30 questions covering the same ground at a higher level. The topic areas below appear on both.

General Driving Knowledge

Every version of the test opens with foundational road knowledge. Expect questions on traffic signs sorted by type: regulatory (speed limits, no-passing zones), warning (curves, railroad crossings), and informational (route markers, distance indicators). Right-of-way at intersections, proper lane usage, and turn signal use come up regularly.

Defensive driving carries heavy weight because you’re carrying people. Questions cover safe following distance, adjusting for rain, snow, fog, and night driving, and how to handle a skid. Speed-management questions usually don’t ask you to recite posted limits. They test whether you understand how road conditions, vehicle weight, and curve severity change what a safe speed actually is.

Vehicle Inspection Questions

Pre-trip inspection is one of the most heavily tested areas. Federal rules require every commercial driver to confirm the vehicle is safe before driving.³ Test questions check what you look for and in what order:

Tires: minimum tread depth, uneven wear, proper inflation, and when a tire must be taken out of service.
Steering and suspension: loose or broken components, leaking power steering fluid, worn steering linkage.
Lights and reflectors: which must work, where reflectors must be placed, and how to test them.
Fluid levels: engine oil, coolant, power steering fluid, and windshield washer fluid.
Emergency equipment: fire extinguishers, spare fuses, and warning triangles.

You’ll also be asked what to do when you find a defect. The right answer is almost always that you don’t drive the vehicle until it’s repaired, and that you document the problem on a vehicle inspection report. On the CDL skills test, an examiner watches you walk around the vehicle and identify components aloud.⁴

Warning Triangles for a Disabled Vehicle

This topic catches people off guard because the numbers are specific and the wrong answers on the test look plausible. When a commercial vehicle stops on the road or shoulder for any reason other than normal traffic, you must turn on hazard flashers immediately and place three warning triangles within 10 minutes.⁵

Placement: one triangle about 10 feet behind the vehicle on the traffic side, one about 100 feet behind in the direction of approaching traffic, and one about 100 feet ahead in the direction away from approaching traffic.⁵ Test questions mix these correct distances with distractors like 50 feet or 200 feet.

Air Brakes

If your vehicle has air brakes, you’ll face a separate technical section. Fail rates run high here. Common question areas:

System components: air compressor, governor, storage tanks, brake chambers, slack adjusters, and what each one does.
Pressure readings: normal operating pressures, when the low-air-pressure warning activates (below 60 psi), and when spring brakes engage automatically (typically 20 to 40 psi).
Inspection: air leakage rate must be less than 2 psi per minute for a single vehicle, pressure should build from 85 to 100 psi within 45 seconds, and you should verify governor cut-in and cut-out pressures.
Technique: why you shouldn’t fan the brakes, how to brake on long downgrades, and what brake fade is.

You can’t skip this section. If your vehicle has air brakes and you don’t pass the air brake knowledge test, you receive a restriction on your license that bars you from driving any air-brake-equipped vehicle.

Passenger Safety

The passenger endorsement portion runs about 20 to 25 questions with the same 80 percent passing threshold. Questions focus on:

Loading and unloading: making sure the path is clear before opening doors, and confirming all passengers have exited safely before pulling away.
Seatbelt enforcement: your responsibility to confirm passengers are buckled in vehicles equipped with belts.
Emergency exits: where they are, how to operate them, and keeping luggage and cargo clear of them.
Passenger conduct: handling disruptive passengers, items passengers can’t bring aboard, and your authority to refuse service when safety is at risk.
Emergency procedures: evacuating after an accident, the correct order of priorities (protect passengers, secure the scene, notify authorities), and where to position passengers away from the vehicle.

Luggage stowage comes up often. The test expects you to know that luggage must be secured so it doesn’t shift during braking or turns, and that nothing gets stored in the aisle or near emergency exits.

ADA and Service Animals

Test questions increasingly cover your obligations under the Americans with Disabilities Act. The most tested topic is service animals. Under the ADA, service animals are dogs trained to perform a specific task for a person with a disability. You must allow them in your vehicle.⁶

When it isn’t obvious what task a dog performs, you may ask only two questions: whether the dog is a service animal required because of a disability, and what task it has been trained to do. You cannot ask about the person’s disability, demand documentation, or ask for a demonstration. Allergies and fear of dogs are not valid reasons to refuse service.⁶ The only grounds for asking someone to remove a service animal are that the dog is out of control and the handler isn’t correcting it, or the dog isn’t housebroken.

If your vehicle is wheelchair-accessible, expect questions on securement, ramp or lift operation, and your obligation to help passengers who need assistance boarding.

Hours of Service

Federal hours-of-service rules limit how long you can drive before resting, and the test checks whether you know the numbers. For passenger-carrying commercial vehicles, you cannot drive more than 10 hours after 8 consecutive hours off duty, and you cannot drive after being on duty for 15 hours following those 8 hours off.⁷

There’s also a weekly cap: 60 hours on duty in any 7 consecutive days if your carrier doesn’t operate every day, or 70 hours in 8 consecutive days if it does.⁷ Questions typically give you a scenario where a driver has been on duty for a specific number of hours and ask whether the driver can legally continue. The math is straightforward, but the questions try to trip you up by mixing driving time with other on-duty time like loading passengers or paperwork.

Scoring, Format, and What to Study

Everything on the written portion is multiple choice. For a full CDL with a passenger endorsement, expect roughly 50 general knowledge questions, 20 to 25 passenger endorsement questions, and an air brake section if applicable. You need 80 percent on each section, and you must pass every section independently. State-specific chauffeur or for-hire tests are usually 20 to 30 questions with the same 80 percent threshold.

Beyond the written exam, the CDL path adds a three-part skills test: a vehicle inspection walkthrough, a basic controls test (backing, parking, turning in a confined space), and an on-road driving test.⁴ You must use a vehicle in the same class you’re applying for.

The best preparation is the official CDL manual or chauffeur handbook published by your state’s motor vehicle agency. Every test question is drawn from that material. Practice tests help you get used to the multiple-choice format and find weak spots. Put extra time into air brakes and pre-trip inspections if those apply to you. Those are where most people need a second try.
