Commercial Driver License

Which type of CDL do I need?

To determine if a CDL is required, the manufacturer's gross vehicle weight rating (GVWR) of the vehicles must be determined.

  • A Class A CDL is required to operate a combination vehicle (truck and trailer) if the gross combined weight rating (GCWR) is 26,001 or more pounds when the gross vehicle weight rating (GVWR) of the trailer, which is added to the GVWR of the power unit (the truck), is 10,001 pounds or more.
  • A Class B CDL is required to operate any vehicle with a GVWR of 26,001 pounds or more. A trailer may be towed if the GVWR of the trailer is 10,000 pounds or fewer.
  • A Class C CDL is required to operate any vehicle with a GVWR of 26,000 pounds or fewer if the vehicle is required to be placarded to transport hazardous materials or if the vehicle transports 16 or more passengers, including the driver. An applicant must also have a passenger (P) or hazardous materials endorsement (HME) to obtain a Class C CDL.

When is a road test required?

A road/skills test is required to apply for a CDL for the first time.

  • to apply to upgrade an existing CDL, such as going from a Class C to a Class B, or a Class B to a Class A.
  • to apply for an endorsement that requires a separate road/skills test, such as in the case of a motorcycle, passenger vehicle and/or school bus. to remove an L (air brake) restriction from an existing CDL.
  • when there is cause to believe an applicant is noncompliant with medical standards and requirements.
  • where the driving privilege has been suspended, canceled or revoked for one year or more. However, a road/skills test may be required at anytime you apply for a license or endorsement.

How many tries do I have to pass the CDL tests?

CDL Knowledge (written) Tests: Upon payment of all applicable fees, you have unlimited attempts to pass the knowledge tests. For a multipart test, if you fail a section but pass another, you receive credit for the passed sections and do not have to repeat them. 

CDL Skills Tests: After obtaining a CDL instruction permit, you may take the skills tests, consisting of a pre-trip inspection, skills test and road test. Upon payment of the skills test fees, you have unlimited attempts to pass the skills tests. The skills test has three parts. If you fail a section but pass another, you receive credit for the passed sections and do not have to repeat them. 

NOTE: If the permit has expired, all knowledge tests must be taken again to obtain a new permit before making another attempt at the skills tests. The CDL instruction permit is valid for twelve months. 

If my CDL is medically suspended and revoked for one year or more, how do I apply for reinstatement?

Pay a reinstatement fee of $30 ($10 for the suspension and $20 for the revocation), $10 for a limited Class D operator license; the cost of an original CDL instruction permit (A and B are $25; C is $12.50), and $10 for each endorsement.

Take all applicable CDL knowledge (written) tests.

A limited Class D operator license is issued; if the CDL written tests are passed, the appropriate class CDL instruction permit is also issued.

A road/skills test is required for certain endorsements (see the next question for more information). If tested by MVD, the fee is $25 for Class A or B CDL skill tests and $12.50 for Class C. Payment of this fee entitles you to three attempts to pass the CDL skill tests.

Payment for reinstatement fees may be made by cash, cashier's check or money order. Some offices accept credit cards. Payment by cash, credit card or both are not accepted by mail. No personal checks are accepted.

A new hazardous materials endorsement (HME) background check will be required if you are not reinstated within a year of a suspension or revocation.
