Montana Class B CDL Practice Questions

This page accompanies a 100-question Montana Class B CDL practice bank. The questions use four answer choices and cover the topics actually present in the saved bank, including general knowledge, air brakes, hazardous materials, tank vehicles, passenger transport, and school bus material. That mix is a study format, not a statement that every Class B applicant must take every endorsement or equipment-specific test. Montana classifies commercial licenses by vehicle size and by intrastate or interstate operation, while endorsements depend on the vehicle and work performed. Applicants should use the current Montana CDL manual and Motor Vehicle Division instructions to identify the tests, medical status, documents, training, and endorsements that apply to their own driving plans.

LICENSING GUIDE

What to know before you test

Use this overview together with the latest official guidance linked below.

Confirm the Class B and operating scope that fits your plan

Start by matching your intended vehicle and operating area to Montana's CDL classifications. Montana describes a Class B license as covering a vehicle exceeding 26,000 pounds GVWR when any trailer is at or under 10,000 pounds GVWR, along with vehicles authorized under Classes C and D. The state also distinguishes interstate from intrastate commercial operation: interstate applicants must be at least 21, while an intrastate Montana CDL may be issued from age 18. Endorsements are separate from the license class. Passenger, school bus, tank, hazardous-materials, and air-brake knowledge can become relevant because of the vehicle, equipment, cargo, or passengers involved, so do not treat every module in this practice bank as universally required.

Prepare documents and medical certification before the written exam

Montana lists document requirements by the credential an applicant already holds. A person with a valid Montana standard driver license should bring that license, proof of authorized presence, and a valid Medical Examiner's Certificate for the CDL written exam. An applicant presenting an out-of-state CDL has a broader list that includes identity, Montana residency, authorized presence, Social Security number, the current out-of-state CDL, and medical certification. Montana also recognizes excepted commercial activities for which medical documentation may not be required. Because document lists can change and individual situations differ, review the MVD required-documents page and the CDL application page before the appointment rather than relying on a practice-question page as a checklist.

Use the CLP period and ELDT requirements in the right order

The Montana process begins with the required CDL written testing. Passing the applicable written test or tests results in a Commercial Learner Permit. For a first Class B CDL, federal Entry-Level Driver Training rules require applicable theory and behind-the-wheel training from a provider listed on the FMCSA Training Provider Registry before the state-administered CDL skills test. First-time passenger and school-bus endorsements also require applicable theory and behind-the-wheel ELDT, while a first hazardous-materials endorsement requires theory training before its knowledge test. Montana states that a CLP must be held for at least 14 days before the CDL skills test, so plan training and test appointments around that waiting period.

Know what the Montana skills test requires

When eligible for the skills test, bring an appropriate test vehicle that is registered, insured, in good operating condition, and within the class for which you are applying. Montana describes three skills-test stages: vehicle inspection, basic control skills, and an on-road test. They must be completed in that order, and each stage must be passed before moving to the next. Failing the vehicle-inspection or basic-control stage ends that attempt and Montana specifies at least a 24-hour wait before retesting; failing the on-road portion after passing the first two carries at least a one-week wait, subject to appointment availability. Use the current Montana instructions when scheduling because appointment procedures and testing logistics can change.

REQUIREMENTS OVERVIEW

Montana CDL Class B requirements

Requirements depend on the applicant and can change. Verify each item with the cited agency.

age

Applicants choosing intrastate or interstate Montana commercial driving privileges

documents

CDL written-test applicant who already holds a valid Montana standard driver license

documents

Applicant presenting a valid out-of-state commercial driver license

Montana lists the valid out-of-state CDL, proof of identity, proof of Montana residency, proof of authorized presence, Social Security number, and a valid Medical Examiner's Certificate for the written-exam appointment.

tests

First-time Montana Class B CDL applicant

Applicants must pass the applicable CDL written testing to receive a Commercial Learner Permit, complete required ELDT when applicable, hold the CLP for at least 14 days, and then take the vehicle-inspection, basic-control, and on-road skills-test segments.

passing

Montana CDL skills-test applicants

Montana requires the vehicle-inspection, basic-control, and on-road skills-test segments to be completed in order, with each segment successfully completed before the applicant moves to the next.

applicability

Montana Class B CDL applicants

Montana describes Class B as a vehicle exceeding 26,000 pounds GVWR towing a trailer at or under 10,000 pounds GVWR, and it allows Class B holders to operate vehicles authorized under Classes C and D. Endorsement and equipment-specific testing depends on the vehicle and operation rather than Class B alone.

applicability

Entry-level Class B applicants and first-time passenger, school-bus, or hazardous-materials endorsement applicants

FMCSA ELDT rules apply to a first Class B CDL and to first-time P, S, or H endorsements, subject to federal exceptions. Class B, P, and S applicants complete applicable theory and behind-the-wheel training before the relevant skills test; H applicants complete theory training before the H knowledge test.
