What you need to know about Maryland's CDL process

A Commercial Driver's License (CDL) in Maryland is issued by the Motor Vehicle Administration (MVA) and allows you to operate trucks, buses, and other large commercial vehicles. The process involves passing a written knowledge test, a skills test, and a medical examination. Maryland requires you to hold a regular driver's license first, then add the commercial endorsement through a separate testing sequence.

The timeline from start to finish typically takes several weeks, depending on how quickly you schedule your tests and whether you pass on your first attempt. You'll need to gather specific documents before you begin, and you must be at least 18 years old (21 if you plan to drive interstate).

Key Takeaways

  • You must hold a valid Maryland driver's license before you can test for a CDL, and you need to pass a medical examination from a certified examiner.
  • The written test covers vehicle operation, safety rules, and endorsement-specific knowledge, and you can study using the Maryland CDL manual available on the MVA website.
  • The skills test includes a pre-trip inspection, a basic control test, and an on-road driving test, all conducted by an MVA examiner.
  • You'll pay separate fees for the knowledge test, skills test, and the CDL license itself, with costs varying based on the class and endorsements you need.

Documents and medical requirements you'll need

Before you schedule any test, gather your current Maryland driver's license, proof of Social Security number, and proof of Maryland residency (such as a utility bill or lease). You'll also need to complete a Medical Examination Report (Form MCSA-5875) from a certified medical examiner listed on the National Registry of Certified Medical Examiners. This form confirms you meet federal health standards for commercial driving.

The medical exam is not optional and cannot be waived. You must bring the completed form to your first appointment at the MVA. If you have any medical conditions—such as diabetes, heart disease, or sleep apnea—disclose them to the examiner, as some conditions require additional documentation or may affect your certification.

The written knowledge test and what it covers

Maryland's CDL knowledge test is computer-based and administered at MVA locations. The test covers general commercial driving knowledge, vehicle inspection, safe driving practices, and hazardous materials handling (if you're seeking that endorsement). You'll answer multiple-choice questions, and you must score at least 80 percent to pass.

Study materials are free: the Maryland CDL Manual is available as a PDF on the MVA website and covers every topic on the test. Many people spend two to four weeks studying before taking the test. You can retake the written test if you don't pass, but you must wait one day before your next attempt.

The skills test: pre-trip inspection, controls, and driving

The skills test has three parts, all conducted by an MVA examiner on the same day. First is the pre-trip inspection, where you walk around and point out key components of the truck (lights, tires, brakes, mirrors) and explain what you're checking for. You don't need to touch anything; you're demonstrating knowledge.

Second is the basic control test, where you operate the vehicle in a closed course to show you can back up, turn, and maneuver safely. Third is the on-road driving test, typically lasting 30 to 45 minutes, where the examiner observes your driving in real traffic. You must pass all three sections to pass the skills test overall.

You'll need to bring a commercial vehicle to the skills test—either your own or one provided by a training school. The vehicle must be the same class as the license you're testing for (Class A, B, or C).

CDL classes and endorsements in Maryland

Maryland issues three classes of CDL based on the vehicle's Gross Vehicle Weight Rating (GVWR). Class A covers vehicles over 26,001 pounds with a trailer over 10,000 pounds. Class B covers single vehicles over 26,001 pounds but no heavy trailer. Class C covers smaller commercial vehicles and is less common.

Endorsements are added to your CDL for specific cargo or vehicle types. The Hazmat (H) endorsement allows you to transport hazardous materials and requires a separate written test and a Transportation Security Administration (TSA) background check. The Passenger (P) endorsement is required to drive buses and also involves a separate test. Other endorsements include Tank (T) for tanker vehicles and Double/Triple (N) for multiple trailers.

Fees and testing locations

Maryland's MVA charges separate fees for each component. The knowledge test fee, skills test fee, and CDL license fee vary, and additional endorsements each carry their own cost. Exact amounts change periodically, so check the MVA website or call your local MVA office for current pricing.

You can take your knowledge test at any MVA office across Maryland. Skills tests are administered at specific MVA locations, and availability varies by location and season. It's common to wait several weeks for a skills test appointment, especially during busy months. Schedule both tests as early as possible once you've passed your knowledge exam.

What happens after you pass

Once you pass both the knowledge and skills tests, the MVA will issue your CDL. You'll receive a physical license in the mail within a few weeks. Your CDL is valid for four years in Maryland, after which you'll need to renew it. Renewals require a new medical examination and may require retesting depending on your record.

If you received any violations or failed either test, you can retake it. There's no limit to how many times you can test, but you must wait at least one day between attempts for the knowledge test and typically longer for the skills test due to scheduling.

Frequently Asked Questions

Do I need to attend a CDL training school?

No, Maryland does not require formal training school attendance. However, many people attend because instructors provide vehicle access for the skills test and teach test-specific techniques. Training schools range from a few days to several weeks and cost varies widely.

Can I use my personal truck for the skills test?

Yes, if it meets the weight and equipment requirements for the class you're testing for. The vehicle must have working brakes, lights, mirrors, and safety equipment. Many people use training school vehicles instead to avoid wear on their own truck.

What disqualifies you from getting a CDL in Maryland?

Certain medical conditions, a suspended or revoked driver's license, and certain criminal convictions can disqualify you. Failing the medical examination is also disqualifying. The MVA can provide a full list of disqualifying factors when you begin the process.

How long does the whole process take?

From your first study session to receiving your CDL in the mail typically takes four to twelve weeks, depending on how quickly you study, pass the knowledge test, and find a skills test appointment. The skills test appointment wait time is the biggest variable.

What if I fail the skills test?

You can retake it. There's usually a waiting period before your next appointment, which varies by MVA location. Many people use the time between attempts to get additional training or practice with a trainer.
