You’re planning to get your Commercial Driver’s License in Maryland — and you’ve chosen a state where CDL drivers are the backbone of one of the busiest freight corridors on the East Coast. Maryland sits at the crossroads of I-95, the massive north-south artery connecting Florida to Maine, and I-70, which stretches westward to the Rockies. The Port of Baltimore, one of the busiest container ports on the Eastern Seaboard, moves millions of tons of cargo every year — all of it requiring skilled commercial drivers to haul it to destinations across the country.
But before you can start hauling containers out of Dundalk Marine Terminal, running freight through the Baltimore-Washington corridor, or navigating the mountain grades of I-68 through western Maryland, you need to pass the Maryland CDL exam. The Maryland Motor Vehicle Administration (MVA) administers the CDL program under federal FMCSA guidelines, and the process is designed to ensure every driver behind the wheel of an 80,000-pound rig understands safety, regulations, and vehicle operation inside and out.
This guide gives you everything you need to prepare for the Maryland CDL test: exact test format, Maryland-specific requirements, what’s different from other states, and free practice tests covering every knowledge exam you’ll face.

Maryland CDL Requirements: What You Need to Know
Maryland follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with some state-specific requirements administered by the Maryland Motor Vehicle Administration (MVA). Here’s exactly what Maryland requires:
Age Requirements in Maryland
| License Type | Minimum Age | Restrictions |
|---|---|---|
| Intrastate (Maryland only) | 18 years | Cannot drive across state lines |
| Interstate (all states) | 21 years | No state-line restrictions |
| HazMat Endorsement | 21 years | Federal requirement — no exceptions |
Maryland CDL Fees
| Fee Type | Amount | Details |
|---|---|---|
| CLP Permit | $90 | Commercial Learner’s Permit application |
| CDL License | $50 | New CDL issuance |
| Endorsement Tests | Varies | Contact local MVA for endorsement fees |
Maryland ELDT Requirements
Since February 7, 2022, all new CDL applicants in Maryland must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. The Maryland MVA verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).
ELDT is required for:
- Original Class A or Class B CDL
- Upgrading from Class B to Class A
- First-time School Bus (S), Passenger (P), or HazMat (H) endorsements
You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 180 days under federal standards.
Medical Certification in Maryland
All CDL holders in Maryland must maintain a valid Medical Examiner’s Certificate (MEC) through the federal National Registry of Certified Medical Examiners. You’ll need to pass a DOT physical exam and keep your medical certification current to avoid having your CDL downgraded. Standard federal medical requirements apply — including self-certification of your driving category (excepted interstate, non-excepted interstate, excepted intrastate, or non-excepted intrastate).
Maryland CDL Test Format: What to Expect
The Maryland CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at Maryland MVA full-service branch offices. Testing is available at locations including Baltimore, Glen Burnie, Columbia, Frederick, Waldorf, and Salisbury on the Eastern Shore.
Knowledge Tests Overview
| Test | Questions | Pass Score | Required For |
|---|---|---|---|
| General Knowledge | 50 | 80% (40 correct) | All CDL classes |
| Air Brakes | 25 | 80% (20 correct) | Class A & B (if vehicle has air brakes) |
| Combination Vehicles | 20 | 80% (16 correct) | Class A |
| HazMat (H) | 30 | 80% (24 correct) | HazMat endorsement |
| Tanker (N) | 20 | 80% (16 correct) | Tanker endorsement |
| Passenger (P) | 20 | 80% (16 correct) | Passenger endorsement |
| School Bus (S) | 20 | 80% (16 correct) | School bus endorsement |
| Doubles/Triples (T) | 20 | 80% (16 correct) | Double/triple trailers |
All Maryland CDL knowledge tests follow FMCSA content standards. The passing score is 80% on every test — no exceptions.
Maryland Skills Test: Three Parts
The Maryland CDL skills test is administered at MVA-approved testing locations. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.
| Section | What It Tests | Details |
|---|---|---|
| 1. Pre-Trip Inspection | Vehicle safety knowledge | Verbally identify and explain critical components: engine, brakes, tires, lights, coupling systems |
| 2. Basic Vehicle Control | Backing and maneuvering | Straight-line backing, offset backing, parallel parking, alley dock |
| 3. On-Road Driving | Real-world driving | Lane changes, turns, braking, gear usage, speed management, traffic law compliance |
Maryland skills test retake policy: If you fail a knowledge test, the waiting period is 1 business day before retaking. For the skills test, you must wait 14 days between attempts. Unlimited retakes are allowed, subject to applicable fees.
What Makes Maryland CDL Different from Other States?
The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But Maryland has specific geographic, economic, and regulatory characteristics that make driving here unique:
Maryland-Specific Driving Conditions
- Port of Baltimore: One of the busiest container ports on the East Coast, the Port of Baltimore moves massive volumes of cargo daily. Drivers hauling containers from Dundalk and Seagirt Marine Terminals need HazMat and Tanker endorsements to handle the diverse cargo flowing through the port, including chemicals, fuels, and bulk liquids
- Chesapeake Bay Bridge: Spanning the Bay between Annapolis and the Eastern Shore, this 4.3-mile bridge is notorious for high winds and weather restrictions. Commercial vehicles face special limitations during storms, and the bridge’s height and exposure require careful planning
- Appalachian Mountain grades: I-68 through western Maryland near Cumberland features significant elevation changes and mountain grades that demand skilled brake management and gear control — especially in winter conditions
- Baltimore-Washington corridor traffic: The I-95/I-695 corridor between Baltimore and DC is one of the most congested freight routes in the nation. Drivers must navigate dense urban traffic, multiple jurisdictions, and tight delivery schedules
- Eastern Shore agriculture: The Delmarva Peninsula is a major poultry and farming region — CDL drivers hauling livestock, grain, and agricultural goods navigate rural two-lane roads and the Bay Bridge crossings daily
- Four-season weather: Maryland experiences the full range — winter snow and ice in the western mountains, spring flooding, summer thunderstorms with flash flooding, and fall hurricane remnants tracking up the Chesapeake Bay. Nor’easters can bring coastal flooding to the Eastern Shore
- Multi-jurisdictional driving: Operating around the DC area means crossing between Maryland, Virginia, and the District of Columbia — each with its own traffic patterns, weight restrictions, and security considerations, especially near federal facilities
- Distribution hub: The Baltimore-Washington corridor is packed with distribution centers for Amazon, FedEx, UPS, and major retailers — making it one of the hottest job markets for CDL drivers on the East Coast
While the CDL knowledge test itself won’t ask you Maryland-specific questions beyond what’s in the standard handbook, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning. If you’re planning to work at the Port of Baltimore or in the distribution corridor, HazMat and Tanker endorsements are especially valuable.

Maryland CDL Frequently Asked Questions
How many questions are on the Maryland CDL General Knowledge test?
The Maryland CDL General Knowledge test has 50 multiple-choice questions. You need to answer at least 40 correctly (80%) to pass. The test covers vehicle inspection, safe driving practices, cargo management, CDL regulations, and more — all following federal FMCSA standards.
How much does a Maryland CDL cost?
The Commercial Learner’s Permit (CLP) costs $90, and the CDL license itself costs $50. Additional costs include your DOT medical exam (typically $75–$150), ELDT training ($3,000–$8,000 if attending a school), and any endorsement test fees. Contact your local MVA branch for the most current fee schedule.
What happens if I fail a Maryland CDL knowledge test?
If you fail a knowledge test in Maryland, you can retake it after waiting 1 business day. For the skills test, the waiting period is 14 days between attempts. Unlimited retakes are allowed, subject to applicable fees. We recommend using our practice tests until you consistently score above 80% before attempting the real exam.
Can I get a Maryland CDL at 18?
Yes. Maryland allows you to get a CDL at 18 for intrastate driving only (within Maryland). You cannot cross state lines until you turn 21. The HazMat endorsement requires you to be at least 21, regardless of your license type.
Where do I take the Maryland CDL skills test?
Maryland CDL skills tests are administered at MVA-approved testing locations. Full-service MVA branch offices are located in Baltimore, Glen Burnie, Columbia, Frederick, Waldorf, and Salisbury (Eastern Shore). You must provide your own vehicle for the test — it must match the class of license you’re applying for.
Is the Maryland CDL test the same as other states?
The knowledge tests are based on the same FMCSA standards and cover the same material as in every other state. Questions about vehicle inspection, safe driving, cargo securement, and endorsements are standardized nationally. Your Maryland CDL is valid in all 50 states. Maryland may have specific administrative procedures and fees, but the exam content is the same nationwide.
Which endorsements are most valuable in Maryland?
Given the Port of Baltimore’s importance and the density of distribution centers in the Baltimore-Washington corridor, HazMat (H) and Tanker (N) endorsements are particularly valuable in Maryland. The Port handles significant chemical and fuel cargo, and employers actively seek drivers with these qualifications. Practice HazMat here or practice Tanker here.
