The 4 and 5 endorsements are separate restrictions on your Ohio commercial driver's license, not upgrades you add to it

The "4" and "5" that appear on your Ohio CDL are restriction codes, not endorsements you request. They limit what you can drive, not what you can do. A "4" means you cannot drive a manual transmission vehicle. A "5" means you cannot drive a tractor-trailer combination (a semi truck with a detachable trailer). These codes appear on your license if you pass your CDL skills test in an automatic transmission vehicle or if you take your combination test in a single unit truck instead of a full tractor-trailer rig.

The confusion happens because Ohio's CDL document lists these as codes alongside actual endorsements like Hazmat or Tanker. They serve the opposite purpose: endorsements expand what you can haul or drive; restrictions narrow it. If you see a "4" or "5" on your license and want to remove it, you must retake the skills test in the vehicle type you were restricted from.

Key Takeaways

  • Restriction "4" means you cannot operate a manual transmission vehicle and must drive automatic only.
  • Restriction "5" means you cannot operate a tractor-trailer combination and are limited to single-unit trucks.
  • These restrictions are placed on your license automatically when you pass your skills test in a vehicle that does not match the full Class A or Class B requirements.
  • To remove either restriction, you must pass the CDL skills test again in the vehicle type you were restricted from.
  • Removing a restriction requires paying the retest fee and scheduling a new skills exam with the Ohio Bureau of Motor Vehicles.

How restriction 4 (manual transmission) gets placed on your license

If you take your Class A or Class B CDL skills test in an automatic transmission vehicle, the Ohio Bureau of Motor Vehicles will place a "4" restriction on your license. This happens regardless of whether you passed the test perfectly. The restriction means you are legally permitted to drive only automatic transmission commercial vehicles.

Many test-takers choose automatic vehicles because they are easier to operate during the skills exam. The test includes backing maneuvers, offset backing, and alley dock exercises that require precise control. An automatic transmission removes the need to manage a clutch and gear shifts during these high-pressure moments, which is why some drivers prefer it. However, the choice locks you into automatic-only operation for the life of that license class.

If your job requires you to operate manual transmission trucks later, or if you want the flexibility to drive either type, you will need to retake the skills test in a manual transmission vehicle. You cannot straightforward request the restriction be removed; the Ohio BMV requires proof that you can handle the manual transmission under test conditions.

How restriction 5 (no tractor-trailer) gets placed on your license

Restriction "5" appears on your Class A CDL if you take your skills test in a single-unit truck (like a straight truck or dump truck) instead of a tractor-trailer combination. A tractor-trailer is a Class A vehicle by definition—the tractor (the powered unit) combined with a detachable trailer. If you test in anything else, Ohio places the "5" on your license, and you cannot legally operate a tractor-trailer.

Some drivers test in single-unit trucks because they are easier to maneuver during the backing and docking portions of the skills test. A straight truck is shorter and has different pivot points than a tractor-trailer, which can make the exam feel more manageable. Others test in a single unit because that is the vehicle their employer provided for the test. Regardless of the reason, the restriction sticks to your license.

If you later need to drive a tractor-trailer for work, you must schedule a new skills test in an actual tractor-trailer combination. The Ohio BMV will not waive this requirement or allow you to remove the restriction without retesting.

Steps to remove restriction 4 from your Ohio CDL

To remove the "4" restriction, you must retake the Class A or Class B CDL skills test in a manual transmission vehicle. The process is the same as your original test: you schedule an appointment with the Ohio Bureau of Motor Vehicles, bring your current CDL and required documents, and complete the three-part exam (pre-trip inspection, basic vehicle control, and on-road driving).

Before you schedule, confirm that you have access to a manual transmission vehicle that meets Ohio's specifications for CDL testing. The vehicle must be the same class as your current license (Class A or Class B). You cannot test in a vehicle that is a different class or that does not match your license type. Contact the Ohio BMV or your local deputy registrar's office to ask which vehicles are approved for testing in your area.

Pay the retest fee when you schedule your appointment. The fee varies depending on your county and the testing location, so call ahead to confirm the amount. Bring your current CDL, proof of residency, and any other documents the BMV requires for a CDL test. When you pass the test in the manual transmission vehicle, the "4" restriction will be removed from your license, and you will be issued a new CDL without it.

Steps to remove restriction 5 from your Ohio CDL

To remove the "5" restriction, you must retake the Class A CDL skills test in a tractor-trailer combination. You cannot remove this restriction by testing in any other vehicle type. The tractor-trailer must be a legitimate Class A combination: a powered tractor unit connected to a detachable trailer with air brakes or equivalent.

Schedule your retest appointment with the Ohio Bureau of Motor Vehicles or your local deputy registrar. Bring your current CDL, proof of residency, and any documents required for a CDL skills test. You will need to arrange access to a tractor-trailer that meets Ohio's testing standards. Some commercial driving schools rent vehicles for testing purposes, or your employer may provide one. Confirm with the testing location that the specific tractor-trailer you plan to use is approved.

When you pass the skills test in the tractor-trailer, the "5" restriction will be removed, and you will receive a new CDL that permits you to operate tractor-trailer combinations. This is the only way to remove the restriction; there is no written test or alternative method.

What happens if you drive with a restriction you do not have

Driving a vehicle that violates your CDL restrictions is a serious violation. If you operate a manual transmission truck while carrying a "4" restriction, or a tractor-trailer while carrying a "5" restriction, you can be cited for driving with an invalid license. The citation is not a minor infraction—it can result in fines, points on your driving record, and potential suspension of your CDL.

Employers also take this seriously. Many commercial carriers run background checks and review CDL records before hiring. A citation for driving outside your restrictions can disqualify you from employment or cause you to lose a job. If you are unsure whether a vehicle matches your restrictions, ask your dispatcher or safety manager before you operate it.

Frequently Asked Questions

Can I remove both restrictions at the same time?

No. You must retake the skills test separately for each restriction. If you have both a "4" and a "5", you will need to schedule two separate test appointments: one in a manual transmission vehicle and one in a tractor-trailer combination. You can schedule them back-to-back if you want to complete them quickly, but they are two separate exams.

Do I have to pay the full CDL test fee to remove a restriction?

Yes. The Ohio BMV charges a retest fee for each skills test, whether it is your first test or a retest to remove a restriction. The fee is the same as the original test fee. Some counties may offer a reduced fee for retests, so contact your local deputy registrar's office to ask about your specific location.

What if I fail the retest?

If you fail the skills test while trying to remove a restriction, the restriction remains on your license. You can schedule another retest appointment and try again, but you will pay the retest fee each time. There is no limit on how many times you can retake the test, but each attempt costs money and requires scheduling a new appointment.

Can I drive a manual transmission vehicle if I have a "4" restriction but my employer requires it?

No. Your CDL restriction is a legal limit, not a suggestion. Your employer cannot override it, and you cannot drive outside your restrictions even if your job depends on it. Your only option is to retake the skills test in a manual transmission vehicle to remove the restriction. If you need the restriction removed urgently, contact your local deputy registrar to ask about expedited testing appointments.

Does a "4" or "5" restriction affect my ability to get other endorsements like Hazmat?

No. Restrictions and endorsements are separate. You can hold Hazmat, Tanker, or other endorsements regardless of whether you have a "4" or "5" restriction. The restriction only limits the type of vehicle you can drive, not what you can carry in it. However, if you have a "5" restriction, you cannot operate a tractor-trailer even with a Hazmat endorsement.
