The Ohio CDL manual is the free study guide published by the Ohio Bureau of Motor Vehicles that covers everything on the commercial driver license knowledge and skills exams: vehicle classes, endorsements, air brakes, pre-trip inspection, and the state and federal rules that apply to heavy and specialized vehicles. It is listed on the BMV’s Documents and Fees page as form HSY 7605, with a Spanish version available as HSY 7606.1Ohio BMV. Documents and Fees You can download the PDF and search it by topic, or pick up a printed copy at most Deputy Registrar locations, though stock varies.
What the Manual Covers
The manual is organized around the credential you are trying to earn. Ohio issues CDLs in three classes, and a higher class automatically authorizes the vehicles in any lower class.2Ohio Legislative Service Commission. Ohio Code 4506.12 – Classes of Licenses – Endorsements and Restrictions
- Class A: Combination vehicles with a combined weight rating of 26,001 pounds or more, where the towed unit alone exceeds 10,000 pounds. Tractor-trailers and most big rigs.
- Class B: Single vehicles of 26,001 pounds or more, or such a vehicle towing a unit of 10,000 pounds or less. Dump trucks, large buses, concrete mixers.
- Class C: Vehicles below the Class A or B weight thresholds that are designed to carry 16 or more passengers (including the driver), transport placarded hazardous materials, or serve as a small school bus.
Endorsements
Certain cargo and passenger types require an endorsement beyond the base class, and each has its own knowledge test:
- H — placarded hazardous materials (also requires a TSA security threat assessment).
- N — tank vehicles carrying liquid or gaseous cargo in permanently mounted tanks.
- P — passenger vehicles designed for 16 or more, including the driver.
- S — school buses transporting children.
- T — double and triple trailer combinations.
- X — combined tanker and hazmat, requiring both the H and N knowledge tests.
Restrictions
The manual also explains restriction codes, which print on the face of the license and limit what you can drive. The one that catches people off guard is the L restriction: if you take the skills test in a vehicle without air brakes, or skip or fail the air brake knowledge test, you cannot operate any vehicle with air brakes until you retest in a properly equipped vehicle. Related codes include Z (no full air brakes, air-over-hydraulic only), E (no manual transmission), and K (intrastate driving only).3eCFR. 49 CFR Part 383 – Commercial Drivers License Standards Driving outside a restriction is treated the same as driving without the proper license.
Who Can Apply and What to Bring
You can apply for a CDL in Ohio at 18, but until you turn 21 you are limited to intrastate driving and cannot haul hazardous materials in interstate commerce. Before you go to the BMV, gather:
- Proof of legal presence — a birth certificate, valid U.S. passport, or permanent resident card. Non-citizens with legal work authorization may qualify for a non-domiciled CDL.
- Social Security verification — your card or an official tax document showing the full number.
- A Medical Examiner’s Certificate (Form MCSA-5876) issued by an examiner on the FMCSA National Registry.4Federal Motor Carrier Safety Administration. Medical Examiners Certificate (MEC), Form MCSA-5876
The BMV’s acceptable documents page shows every combination it will accept.5Ohio BMV. Acceptable Documents
Self-Certification
Every applicant self-certifies which type of commercial driving they will do. The four categories are Non-Excepted Interstate (NI), Non-Excepted Intrastate (NA), Excepted Interstate (EI), and Excepted Intrastate (EA). Only the non-excepted categories require you to keep a current medical card on file with the BMV. If your work spans more than one category, certify to the broader one so you remain legal across the board.6Federal Motor Carrier Safety Administration.

The Knowledge Tests and Learner Permit
The knowledge tests come straight out of the manual. The general knowledge exam follows the federal standard of 50 questions with a passing score of 80 percent, meaning 40 correct answers. Each endorsement adds its own separate test at the same session, and the BMV screens your vision before you begin.
Once you pass, you get a Commercial Learner Permit. Federal law requires you to hold the CLP for at least 14 days before attempting the skills test, and while you carry it a licensed CDL holder must sit in the passenger seat any time you operate a commercial vehicle. Only three endorsements can be added to a CLP: P, S, and N. Even with those, a P or S permit prohibits carrying anyone other than the supervising CDL holder, examiners, and trainees, and an N permit restricts you to empty tanks. If the CLP expires and you renew it, any skills test segments you already passed become invalid and you retake all three.
The Skills Test
The skills exam is administered in three parts, either at a state site or an authorized third-party location.
Pre-Trip Vehicle Inspection
You walk around the vehicle with the examiner and identify safety items across the engine compartment, cab interior, external lights, tires, coupling devices, and brake system. The air brake check alone runs through several steps: confirming the compressor builds pressure, testing for leaks, verifying the low-pressure warning activates before pressure drops below 60 PSI, confirming the spring brakes engage automatically as pressure falls, and performing service and parking brake tests. This section of the manual rewards extra study time; a missed step here can fail you before the engine ever runs.
Basic Control Skills
On a controlled area away from public roads, you perform maneuvers like straight-line backing, offset alley docking, and parallel parking. You are scored on accuracy, pull-ups, and whether you hit boundary markers.
On-Road Driving
The final segment puts you in live traffic. The examiner watches how you handle intersections, lane changes, highway merges, curves, and railroad crossings, along with braking, mirror use, and following distance.
Entry-Level Driver Training
Studying the manual is not the whole picture. Federal Entry-Level Driver Training rules require most new applicants to complete an approved course before they can take the skills test. ELDT applies to anyone getting a Class A or B CDL for the first time, upgrading from a lower class, or adding a P, S, or H endorsement for the first time.7eCFR. 49 CFR Part 380 Subpart F – Entry-Level Driver Training Requirements
Training splits into theory instruction and behind-the-wheel work on both a closed range and public roads. There is no federal minimum hour count, but you must score at least 80 percent on the theory assessment, and both portions must be completed within one year of each other. Your provider has to appear on the FMCSA Training Provider Registry, and once you finish, the provider reports your completion to FMCSA by midnight of the second business day.8Training Provider Registry. Training Provider Registry The BMV checks that electronic record before it will schedule your skills test.
Fees
Ohio’s CDL costs are spread across the process:
- Commercial Learner Permit: $10.00
- CDL issuance (first time): $25.00, plus a $12.00 fee applied to all license transactions
- Skills test: $50.00 from the state ($10 pre-trip, $10 basic controls, $30 on-road), plus up to $85.00 at a third-party site
- Duplicate CDL: $10.00
These are state-set amounts and do not cover ELDT tuition, the DOT physical, or the TSA threat assessment for a hazmat endorsement. Deputy registrar processing fees vary by location.9Ohio Legislative Service Commission. Department of Public Safety Agency Fees
If you are going after the H endorsement, budget for the TSA security threat assessment separately. The fee is $85.25, or $41 if you already hold a Transportation Worker Identification Credential. TSA recommends starting at least 60 days ahead because processing can take more than 45 days, and certain criminal convictions or incomplete applications can result in a denial.10Transportation Security Administration.

What Can Cost You the License
The manual devotes space to disqualifications, and the numbers are worth knowing before the situation arises. Under Ohio Revised Code 4506.16, a first conviction for a major offense like DUI, leaving the scene of an accident, or using a commercial vehicle to commit a felony triggers a one-year disqualification. A second major offense from a separate incident is a lifetime disqualification. The first-offense penalty rises to three years if the offense happens while you are hauling placarded hazardous materials.11Ohio Legislative Service Commission. Ohio Code 4506.16 – Violations – Disqualification of Driver Out-of-service order violations carry their own escalating schedule, starting at 180 days for a first violation and climbing with repeats within a 10-year window.
