To meet Maine CDL requirements, you need to be old enough for the type of driving you’ll do, pass a DOT physical, complete federal Entry-Level Driver Training, get a commercial learner permit by passing written knowledge tests at a Bureau of Motor Vehicles branch, hold that permit for at least 14 days, and then pass a three-part skills test. State fees start at $70 for the exam plus $34 to $59 for the license itself, with more added for endorsements and the medical and training costs paid outside the BMV.
Who Qualifies
Age is the first filter. Federal law requires drivers to be 21 to operate a commercial vehicle across state lines. At 18, 19, or 20 you can hold a Maine CDL, but you’re limited to intrastate routes.1Federal Register. Commercial Drivers Licenses Pilot Program To Allow Drivers Under 21 To Operate Commercial Motor Vehicles If a prospective employer runs loads into New Hampshire or beyond, you need to be 21 regardless of what class you hold.
Federal rules also require that you can read and speak English well enough to understand road signs, talk with the public and officials, and complete reports.2Federal Motor Carrier Safety Administration. 49 CFR 391.11 General Qualifications of Drivers
Every applicant needs a current medical examiner’s certificate from a provider on the FMCSA’s National Registry, documented on Form MCSA-5876.3Federal Motor Carrier Safety Administration. Medical Examiners Certificate, Form MCSA-5876 Exams generally run $50 to $150 out of pocket, and the certificate is valid for up to two years. Certain medical conditions shorten that to one year. When you apply at the BMV, you’ll also self-certify which operating category you fall into (interstate or intrastate, excepted or non-excepted), which controls whether the BMV needs a DOT medical card on file.4Federal Motor Carrier Safety Administration. How Do I Determine Which of the 4 Categories of Commercial Motor Vehicle Operation I Should Self-Certify
Picking a Class and Any Endorsements
Maine issues three CDL classes based on vehicle weight and configuration:5Maine State Legislature. Maine Code Title 29-A 1252 – Classes
- Class A covers combination vehicles with a gross vehicle weight rating of 26,001 pounds or more where the towed unit weighs more than 10,000 pounds. Most tractor-trailers fall here.
- Class B covers single vehicles at 26,001 pounds or more, or those towing a trailer at or under 10,000 pounds. Dump trucks, large buses, and box trucks are typical.
- Class C covers vehicles that don’t meet A or B thresholds but still need a CDL because they’re placarded for hazardous materials or carry 16 or more passengers including the driver.
A Class A license also authorizes Class B and C vehicles, and Class B covers C. If you might drive more than one type of commercial vehicle, testing once at the highest class saves a second round later.
Endorsements expand what you can haul or who you can carry: H for hazmat, N for tank, T for doubles and triples, P for passenger buses, S for school buses carrying more than 15 passengers, and X for the hazmat-plus-tank combination.6Maine Secretary of State. Maine License Endorsement and Restriction Codes Each has its own written test. Hazmat also requires a TSA background check with fingerprinting, which costs $85.25 for most applicants.7Transportation Security Administration. HAZMAT Endorsement
Documents You’ll Bring to the Branch
Before any testing, you need identity and residency documentation at a BMV branch. For a REAL ID commercial license, that means two documents proving Maine residency, such as a utility bill and a signed lease, plus proof of legal presence like a birth certificate or valid passport.8Maine Secretary of State. How to Prove Maine Residency Bring the medical examiner’s certificate too.
Entry-Level Driver Training
Since February 2022, first-time Class A and Class B applicants, drivers upgrading from B to A, and anyone adding a hazmat, passenger, or school bus endorsement must complete Entry-Level Driver Training through an FMCSA-registered provider.9Federal Motor Carrier Safety Administration. Entry-Level Driver Training The BMV will not let you schedule the skills test until your provider has uploaded your completion record to the federal Training Provider Registry.
Training has two parts. Theory instruction covers vehicle controls, pre-trip inspection, shifting, backing, coupling, hazard perception, and related topics, and ends with an assessment you must pass at 80% or better. There’s no mandated classroom hour count. Behind-the-wheel training includes closed-course maneuvers and public road driving, and your instructor signs off when you’ve shown proficiency in each required skill.10eCFR. 49 CFR Part 380 – Special Training Requirements You can confirm your record is on file through the Training Provider Registry.11Federal Motor Carrier Safety Administration. Training Provider Registry
Commercial Learner Permit and Written Tests
With documents, medical card, and theory training complete, you visit a BMV branch to apply for the commercial learner permit. The examination fee is $70 for any CDL class, plus $20 per endorsement test.12Maine Secretary of State. Drivers License and Examination Fees You’ll take the general knowledge test covering traffic laws, vehicle safety, and cargo handling, plus any endorsement knowledge tests the same day.
Passing earns a CLP valid for up to one year.13eCFR. 49 CFR 383.73 – State Procedures It lets you practice in a commercial vehicle, but only with a CDL holder in the passenger seat who’s licensed for the class and endorsements of that vehicle. Carry the CLP any time you’re driving. You must hold it at least 14 days before you’re eligible to take the skills test, so don’t book that appointment for the day after your written exams.14eCFR. 49 CFR 383.25 – Commercial Learner Permit
The Three-Part Skills Test
The CDL skills test has three segments, and you need to pass each one to move to the next.15Maine Secretary of State. Maine Commercial Driver License Manual
Pre-Trip Vehicle Inspection
You walk the vehicle, point to or touch each component, and tell the examiner what you’re checking and why. Class A applicants also inspect the coupling system between tractor and trailer. The point is showing you’d catch a safety defect before leaving the yard.
Basic Vehicle Control
On a closed course, you work through exercises like straight-line backing, offset alley, parallel parking, and alley docking. Hitting a cone or crossing a boundary counts as an encroachment. You get one pull-up per exercise and can exit the cab once per attempt to check your position. Finishing in the wrong final position disqualifies that segment.
On-Road Driving
The examiner routes you through live traffic including turns, intersections, railroad crossings, curves, grades, and highway driving. You’re scored on lane position, speed, mirror use, signaling, and overall safe driving. Pass all three segments and you head back to the BMV to finish the license.
Restrictions Worth Avoiding
The vehicle you test in sets the limits of what you can later drive. Two restrictions catch new drivers:
- The L restriction (no air brakes) applies if you test in a vehicle without them, and it bars you from any commercial vehicle equipped with air brakes. Since most tractor-trailers have air brakes, this effectively shuts you out of most Class A work. Removing it means passing the air brake knowledge test and retaking the skills test in a vehicle with a full air brake system.
- The E restriction (automatic transmission only) applies if you test in an automatic. Removing it means retaking the skills test in a manual.
Train and test in a manual-transmission vehicle with full air brakes and neither restriction appears.
What It Costs
Maine splits the cost into examination fees and licensing fees, paid separately:12Maine Secretary of State. Drivers License and Examination Fees
- CDL examination: $70 for Class A, B, or C
- Each endorsement exam: $20
- License issuance under 65: $34 for a standard five-year license, $59 for REAL ID
- License issuance 65 and older: $27 for a standard four-year license, $47 for REAL ID
A first-time Class A applicant under 65 with one endorsement and a REAL ID license pays $70 + $20 + $59 = $149 in state fees. The DOT physical, ELDT tuition, and any TSA hazmat background check are on top of that.
Military Skills Test Waiver
Current and former service members who operated trucks or buses equivalent to civilian commercial vehicles for at least two years can waive the skills test. The written knowledge exams and other requirements still apply, and you have to apply within one year of leaving the qualifying military position.16Federal Motor Carrier Safety Administration. Military Skills Test Waiver Program You also need to certify a clean driving record, no more than one license in the past two years (military licenses don’t count), no state license suspension or revocation, and no disqualifying CDL offenses. The CDL class you receive matches what you drove in service.
Keeping the License
A Maine CDL runs five years if you’re under 65 and four years if you’re 65 or older, with renewal fees matching the initial licensing fees. Keep the medical certificate current throughout. If your DOT medical card lapses, the BMV downgrades your CDL status until you provide a new one. Hazmat endorsements require a new TSA background check at every renewal.7Transportation Security Administration. HAZMAT Endorsement
Losing a CDL is easier than earning one. The BAC limit for commercial drivers is 0.04%, half the standard limit. A reading at or above that while operating a commercial vehicle triggers an automatic one-year disqualification, or three years if you were hauling hazardous materials. A second major offense of any kind is a lifetime disqualification. Using a commercial vehicle in drug or human trafficking brings a lifetime ban with no reinstatement.17eCFR. 49 CFR 383.51 – Disqualification of Drivers These rules reach your personal driving too: a DUI in your own car on a Saturday night still disqualifies your CDL for a year.
