A non-exempt truck-and-trailer combination has a gross combination weight rating of 32,000 pounds and a trailer GVWR of 12,000 pounds. Which CDL group is required for that combination?
Correct answer: Class A.
This combination meets both Class A thresholds: a GCWR of at least 26,001 pounds and a towed-vehicle GVWR above 10,000 pounds.

A non-exempt straight truck has a GVWR of 30,000 pounds and does not tow a trailer. What is the minimum CDL class that covers it?
Correct answer: Class B.
A single vehicle rated at 26,001 pounds or more falls in Class B. A heavier combination with a trailer over 10,000 pounds is a different classification.

A non-exempt bus is designed for 17 people, including its driver, and is too light to fall in Class A or B. Which CDL group applies?
Correct answer: Class C, with the required passenger qualification.
Class C includes vehicles outside Classes A and B that are designed for at least 16 people including the driver. The design capacity, not just today's occupancy, matters.

Two otherwise qualified Montana applicants want commercial freight jobs: one is 18 and one is 21. Which age boundary does Montana MVD state for its ordinary CDL types?
Correct answer: Intrastate applicants must be at least 18; interstate applicants must be at least 21.
Montana lists age 18 for its Montana-only intrastate CDL and age 21 for its interstate CDL. Meeting the age requirement does not remove other licensing qualifications.

A Montana applicant has met all CLP issuance requirements. How long does the current manual say the newly issued CLP is valid?
Correct answer: One year from its issue date.
The Montana supplement specifies a one-year CLP. The learner must still obey supervision, vehicle and endorsement limits throughout that period.

A Montana CLP holder is practicing in a commercial truck on public roads. Which supervisor meets the federal accompaniment requirement, assuming that person is otherwise authorized for the trip?
Correct answer: A valid CDL holder with the needed class and endorsements, in the front seat beside the learner and directly supervising.
For this truck practice, the accompanying driver must have the proper CDL group and endorsements and sit beside the learner under observation and direct supervision. A following vehicle or sleeper berth is not sufficient.

A Montana applicant finishes the required training seven days after the CLP is issued. May the applicant take the CDL skills test immediately?
Correct answer: No. The CLP must still be held through the required 14-day period.
Training completion does not waive Montana's CLP holding period. The manual requires at least 14 days and says testing may occur on the 15th day.

Which vehicle should a Montana applicant provide for a CDL driving test?
Correct answer: A vehicle in the class sought, in good operating condition, currently registered and insured.
The Montana manual requires the applicant's test vehicle to be within the applied-for class, in good operating condition, registered and insured. It also specifies seatbelts and a passenger seat.

A Montana applicant seeks a first Class A CDL and no ELDT exception applies. When must required training from a registered provider be completed?
Correct answer: Before taking the Class A CDL skills test.
Covered first-time Class A or B applicants must complete the required entry-level training before skills testing. Passing a knowledge test is not a substitute for that training.

A CDL holder seeks a hazardous-materials endorsement for the first time and has no ELDT exception. When is the required registered-provider training needed?
Correct answer: Before taking the hazardous-materials endorsement knowledge test.
For a covered first H endorsement, required training precedes the endorsement knowledge test. The timing differs from the skills-test prerequisite used for first Class A or B licenses.

A first-time Montana hazardous-materials endorsement applicant passes the knowledge test. Is that score alone enough to establish security eligibility?
Correct answer: No. The applicable TSA security threat assessment must also be completed.
Montana's supplement separately requires the federal TSA security threat assessment for hazardous-materials endorsement applicants. A passing knowledge score does not replace it.

A driver holds the proper CDL class but has an L restriction. May the driver operate that class of commercial vehicle with air brakes?
Correct answer: No. L prohibits operating an air-braked commercial motor vehicle.
An L restriction limits air-brake-equipped CMV operation. Holding the correct vehicle class alone does not remove the equipment restriction.

A Montana applicant takes the CDL skills test in a commercial vehicle with an automatic transmission. Which equipment restriction normally results?
Correct answer: An E restriction prohibiting manual-transmission commercial vehicles.
The Montana supplement assigns E when the test is taken in an automatic-transmission CMV. The restriction concerns manual-transmission commercial vehicles, not ordinary car operation.

A driver is qualifying for a school bus that requires a CDL. Does the school-bus endorsement eliminate the passenger-endorsement qualification?
Correct answer: No. The driver must qualify for both passenger and school-bus endorsements.
The Montana supplement expressly states that school bus drivers also need the passenger endorsement. The two qualifications are not interchangeable.

A Montana CDL applicant expects to do only medically excepted commercial work. May the applicant skip self-certification entirely?
Correct answer: No. The applicant must still identify the applicable type of operation.
Self-certification identifies interstate or intrastate operation and whether it is excepted or non-excepted. A medical exception is a category to identify, not permission to omit the process.

A Montana driver performs both excepted and non-excepted interstate commercial work. Which medical self-certification category must cover those duties?
Correct answer: Non-excepted interstate.
The Montana supplement says a driver performing both types of interstate work must choose non-excepted interstate to be qualified for both. The excepted category alone does not cover the non-excepted trips.

After a Montana CLP/CDL medical exam, what matches MVD's current standard medical-result reporting process?
Correct answer: The medical examiner submits the result to the National Registry, which sends it electronically to MVD.
The June 2026 supplement says the examiner enters the MEC into the National Registry and the registry forwards it to MVD. A driver may keep a paper copy, but MVD no longer accepts paper cards as the filing method.

A Montana non-excepted CDL driver needs a new Medical Examiner's Certificate. What qualification should the driver check when choosing the examiner?
Correct answer: The medical professional is listed on the National Registry of Certified Medical Examiners.
MVD requires the relevant medical examination to be performed by a professional on the National Registry. A prior patient relationship or employer connection does not replace that qualification.

A Montana intrastate CDL driver who must maintain an MEC lets it expire. The record now says “Not Certified,” not “downgraded.” May the driver continue commercial driving on that basis?
Correct answer: No. Commercial privileges are invalid until the required valid MEC is submitted through the examiner's registry process.
MVD specifically distinguishes intrastate “Not Certified” status from a downgrade. The label does not authorize driving: commercial privileges remain invalid until the required valid medical certification is supplied.

A Montana CDL holder becomes subject to a CMV driving prohibition recorded in the federal Drug and Alcohol Clearinghouse. What does MVD say happens to existing CDL privileges?
Correct answer: MVD removes the commercial privileges and downgrades the license until the required return-to-duty process is completed.
MVD's current notice says it denies a credential application subject to a CMV prohibition and removes existing CDL privileges until the Clearinghouse return-to-duty requirements are satisfied.
