Ohio Class B CDL Practice Questions and Licensing Guide

This Ohio Class B CDL practice page is built around the 100 questions currently saved in the bank. The mixed set covers general knowledge, air brakes, hazardous materials, tank vehicles, passenger transport, and school bus material. Those specialty modules are broad study coverage, not a claim that every Class B applicant must take every endorsement test. Ohio law defines Class B around a qualifying heavy single vehicle, including limited towing, while Ohio BMV ties required knowledge and skills testing to the CDL class, endorsements, restrictions, and vehicle involved. First-time Class B applicants must also account for Entry-Level Driver Training before the skills test. Use the questions to review the topics actually present in this bank, then use the guide below to separate the core Ohio Class B licensing path from conditional endorsement and equipment requirements.

LICENSING GUIDE

What to know before you test

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

Confirm that Class B matches the vehicle you plan to drive

Ohio law defines Class B as a single vehicle with a gross vehicle weight or gross vehicle weight rating of 26,001 pounds or more, including such a vehicle towing another vehicle whose gross vehicle weight or rating does not exceed 10,000 pounds. Ohio BMV requires knowledge testing applicable to the class of commercial vehicle and any endorsements sought. This practice bank therefore emphasizes heavy straight-vehicle knowledge and includes conditional air-brake, tank, hazardous-materials, passenger, and school-bus material. Combination-vehicle and doubles/triples modules are not included in this Class B bank because those are not regular Class B operating modules.

Meet the first-time applicant, document, vision, and medical steps

Ohio BMV says first-time CDL applicants must be at least 18, hold a valid Ohio driver license, have a valid U.S. Social Security number, and provide accepted proof of U.S. citizenship or lawful permanent residency. Applicants must also satisfy vision and applicable FMCSA physical qualifications. Drivers under 21 are restricted to intrastate commercial driving within Ohio. CDL and CLP applicants self-certify the type of commercial driving they will perform, and current medical examination results are generally transmitted electronically to Ohio BMV through the federal registry process rather than being handed in as a paper certificate by the driver.

Move from knowledge testing and the CLP to the Class B skills test

Ohio BMV requires applicants to pass the knowledge tests that apply to the Class B vehicle and requested endorsements, purchase a commercial learner permit, complete applicable Entry-Level Driver Training, and pass the required skills testing. FMCSA states that a CLP must be held for at least 14 days before the CDL skills test. Ohio lists skills testing as pre-trip inspection, basic maneuverability, and a road test, using a vehicle appropriate for the class and endorsements sought. The test vehicle and its equipment can affect restrictions, including air-brake, passenger-vehicle, and transmission restrictions, so applicants should test in a vehicle representative of the Class B privileges they need.

Know the official knowledge-test thresholds and use this bank as broader practice

Ohio Administrative Code requires at least 50 equally weighted general commercial-driver questions with 80 percent correct to pass. It also sets 80-percent thresholds for applicable specialty tests, including hazardous materials, passenger transport, tankers, school bus, and air brakes. This saved practice bank instead contains 100 editorial questions distributed across six modules for broader preparation, with extra general-knowledge coverage because Class B does not ordinarily require the Class A combination or doubles/triples modules. Its question count and module allocation are not presented as an official Ohio exam blueprint. Focus additional study on the specialty tests, endorsements, and equipment that match the vehicle, cargo, and passengers you actually intend to operate.

REQUIREMENTS OVERVIEW

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

age

First-time Ohio CDL applicants, including drivers under age 21

Ohio BMV requires first-time CDL applicants to be at least 18 years old. Drivers under 21 are restricted to intrastate commercial driving within Ohio.

documents

First-time Ohio Class B CDL and CLP applicants

Ohio BMV requires a valid Ohio driver license, a valid U.S. Social Security number, and accepted proof of U.S. citizenship or lawful permanent residency for first-time CDL applicants. Applicants also complete the applicable commercial-driving self-certification and medical qualification process.

tests

First-time Ohio Class B applicants and applicants seeking applicable endorsements or air-brake privileges

Applicants must satisfy the vision requirement and pass the knowledge tests applicable to the CDL class and requested endorsements, obtain a CLP, complete applicable Entry-Level Driver Training, hold the CLP for the federal 14-day minimum before the skills test, and pass the required pre-trip, basic maneuverability, and road-test components in an appropriate vehicle.

passing

Ohio commercial driver applicants taking required knowledge examinations

Ohio Administrative Code requires 80 percent correct on the general commercial knowledge test and on each applicable specialty knowledge test. The rule specifies at least 50 general questions, plus separate question counts for hazardous materials, passenger, tanker, school bus, air-brake, and other specialty testing when applicable.

applicability

Ohio Class B applicants and Class B holders studying endorsement-specific or equipment-specific material

Ohio Class B covers a qualifying single vehicle of 26,001 pounds or more, including limited towing of a vehicle not exceeding 10,000 pounds. Endorsements and restrictions depend on the actual vehicle, equipment, cargo, and passenger operation, so the five specialty modules in this 100-question mixed bank do not all apply to every Class B applicant.
