How long does it take to get a CDL license?

Getting a CDL typically takes 3–7 weeks from starting training to receiving your license. The process requires: passing the CDL knowledge test and obtaining a Commercial Learner's Permit (CLP), holding the CLP for at least 14 days, completing CDL training (3–7 weeks depending on the program), and passing the CDL skills test (pre-trip, basic controls, and road test). After passing the skills test, your CDL is issued at your state DMV — typically within a few days. Private CDL school programs run 3–4 weeks for full-time students; community college programs may take 8–12 weeks.

What is the difference between CDL Class A and Class B?

Class A CDL is required for combination vehicles (truck + trailer) with a Gross Combination Weight Rating (GCWR) of 26,001 lbs or more, where the trailer weighs more than 10,000 lbs. This includes semi-trucks, tractor-trailers, and 18-wheelers. Class B CDL is required for single vehicles (no trailer over 10,000 lbs) with a Gross Vehicle Weight Rating (GVWR) of 26,001 lbs or more — including large straight trucks, city buses, dump trucks, and garbage trucks. Class A holders can also operate Class B and C vehicles; Class B holders can operate Class C but not Class A combination vehicles.

Can you get a CDL at 18?

In most states, you can get a CDL at age 18 for intrastate (within your state) commercial driving. Federal interstate CDL requirements set the minimum age at 21. However, the federal infrastructure law created a pilot apprenticeship program that allows 18–20 year-olds to drive interstate under strict supervision — check FMCSA's apprenticeship program for current eligibility and participating carriers. Some states have additional restrictions for 18–20-year-old CDL holders, such as limits on night driving or driving in adverse conditions.

How much does CDL training cost?

CDL training cost ranges from $0 (employer-sponsored paid training programs) to $10,000+ (private CDL schools). Community college CDL programs typically cost $1,500–$5,000. The most cost-effective path for many candidates is employer-sponsored training through major trucking carriers — you receive a salary during training and pay nothing out of pocket, but commit to driving for the company for 1–2 years. State-level truck driver training grants are also available in some states through workforce development boards — check your state's workforce agency for current CDL training assistance programs.

What disqualifies you from getting a CDL?

Major disqualifying factors include: more than one DUI/DWI conviction, having a license suspended, revoked, or cancelled in any state, using a false identity to obtain a CDL, leaving the scene of a serious accident while operating a CMV, and committing a felony involving a motor vehicle. Additionally, certain medical conditions — including some heart conditions, vision impairments, and use of disqualifying medications — can prevent CDL issuance or require federal medical exemptions. Drug and alcohol violations result in disqualification from commercial driving until completing a return-to-duty process through a DOT-qualified substance abuse professional.

CDL License 2026–2026 — Requirements, Classes, and How to Get Certified

CDL Classes: Class A, Class B, and Class C

The CDL class you need depends on the type of commercial vehicle you will drive. Federal regulations under 49 CFR Part 383 define the three CDL classes.

Class A CDL: Required for any combination of vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 lbs or more, where the towed vehicle(s) weigh more than 10,000 lbs. This includes semi-trucks (tractor-trailers), flatbed trucks, livestock carriers, and most 18-wheelers. Class A holders can also operate Class B and Class C vehicles. This is the most comprehensive CDL and the most in-demand for long-haul trucking careers.

Class B CDL: Required for single vehicles with a Gross Vehicle Weight Rating (GVWR) of 26,001 lbs or more, OR vehicles towing a trailer 10,000 lbs or less. Includes straight trucks, box trucks, dump trucks, garbage trucks, city buses, and school buses. Class B holders can also operate Class C vehicles but not Class A combination vehicles without upgrading their license.

Class C CDL: Required for vehicles not meeting Class A or B weight thresholds but designed to transport 16 or more passengers (including driver), or placarded hazardous materials. Includes passenger vans, small shuttle buses, hazmat vehicles, and certain emergency vehicles. Class C CDL is the most limited of the three classes.

Which class do you need? Most professional truck driving careers require Class A CDL. Class B is commonly required for bus drivers, local delivery drivers, and sanitation workers. Class C is less common and typically applies to specific niche commercial vehicle roles. Consult your employer or the vehicle's GVWR documentation to confirm which class applies.

CDL License Requirements 2025–2026

Federal CDL requirements are set by the Federal Motor Carrier Safety Administration (FMCSA) and apply in all 50 states. States may add requirements beyond the federal minimums.

Age requirements:

Intrastate (within your state only): You can get a CDL at age 18 in most states. You will be restricted to driving within your state's borders.
Interstate (crossing state lines): Federal law requires age 21 to drive commercially across state lines. The federal Infrastructure Investment and Jobs Act created an apprenticeship program allowing 18–20-year-olds to drive interstate under supervision — check FMCSA for current program status in your state.

Medical requirements:

Pass a DOT physical examination conducted by a FMCSA-registered medical examiner. The medical certificate must be current and on file with your state DMV.
Vision requirements: at least 20/40 in each eye (with correction), adequate peripheral vision
Certain medical conditions (insulin-dependent diabetes, epilepsy, hearing impairment) require special federal exemptions

Driving record requirements:

Only one state can issue your CDL — you must surrender licenses from other states
Cannot have had your license suspended, revoked, or cancelled in any state
DUI/DWI convictions are major disqualifying offenses — one lifetime disqualification for a second CDL-related DUI
Drug and alcohol testing: pre-employment, random, post-accident, and return-to-duty testing are mandatory under FMCSA regulations

Commercial Learner's Permit (CLP): You must hold a CLP for at least 14 days before taking the CDL skills test. The CLP is issued after passing the CDL knowledge test and requires a valid medical certificate. With a CLP, you can practice driving a CMV accompanied by a CDL holder with at least 1 year of experience in the vehicle type.

Prepare for the knowledge test with our CDL general knowledge practice test, and use our full CDL practice tests collection for endorsement-specific preparation. Our CDL air brakes practice content is essential for Class A applicants who need the air brakes endorsement.

CDL Exam Format — Knowledge Test and Skills Test

The CDL licensing process requires two separate exams: a written knowledge test and a practical skills test. Both must be passed in your state of legal domicile (where you are a resident).

CDL Knowledge Test (written):

General Knowledge test: Required for all CDL applicants — 50 questions covering CDL rules, safe driving, vehicle inspection, cargo handling, and emergency procedures. Passing typically requires 80% (40/50 questions correct).
Combination Vehicles (Class A): Additional 20-question test on coupling/uncoupling, trailer handling, and combination vehicle safety
Air Brakes: Required for most Class A vehicles — 25-question test. Passing removes the air brakes restriction from your CDL.
Endorsement tests: H (hazardous materials), N (tank vehicles), P (passenger), S (school bus), T (double/triple trailers) — each is a separate 20–30 question test

CDL Skills Test (practical):

Pre-Trip Inspection: You identify and explain vehicle components during a thorough safety inspection while the examiner scores your accuracy
Basic Vehicle Controls: Backing maneuvers — straight back, offset back, alley dock, parallel park. Demonstrates your ability to control the vehicle in tight situations.
On-Road Driving Test: Evaluated on lane changes, turns, intersections, railroad crossings, and traffic compliance

The skills test must be taken in the same class of vehicle you are seeking licensure for. Most CDL schools provide the test vehicle.

CDL License Application Checklist

Confirm which CDL class you need (A, B, or C) based on the vehicle type and weight you will operate — talk to your employer or check the vehicle GVWRSchedule and pass your DOT physical examination with a FMCSA-registered medical examiner — the medical certificate is required before applying for your CLPVisit your state DMV with your medical certificate, identity documents, and proof of state residency to apply for your Commercial Learner's Permit (CLP) and take the knowledge testStudy the CDL General Knowledge test (federal and state-specific questions) — also study endorsement-specific sections (air brakes, hazmat, combination vehicles) relevant to your vehicle typeAfter receiving your CLP, practice driving for at least 14 days (CLP minimum hold period) before scheduling your skills test — practice pre-trip inspection until it is completely memorizedEnroll in a CDL school or employer-sponsored training program for structured behind-the-wheel instruction and access to a test vehicle for the skills examResearch employer-paid CDL training programs — many major carriers (Werner, Schneider, Roehl, Swift) offer paid training with a driving contract commitment of 1–2 yearsAfter passing both tests, apply for your CDL at your state DMV — carry your CLP, passed skills test paperwork, and current medical certificate

CDL Training Programs and Cost

CDL training is not federally required before taking the CDL knowledge test, but the skills test requires behind-the-wheel practice, and most applicants use a structured training program to prepare for both tests.

Types of CDL training programs:

Employer-sponsored paid training: Major trucking companies offer paid CDL training programs where you receive a salary during training in exchange for committing to drive for the company for 1–2 years after receiving your license. This eliminates out-of-pocket training costs. Programs from carriers like Werner, Schneider, Roehl, Swift, and CR England are widely available. The trade-off is a below-market starting salary during the first year of your driving contract.
Private CDL schools: Focused, intensive programs typically 3–7 weeks. Costs range from $3,000 to $10,000+. Many private schools have job placement partnerships with carriers. Financing options including student loans and payment plans are often available.
Community colleges: Some community colleges offer CDL programs through their workforce development departments at lower tuition ($1,500–$5,000) but may have longer program durations and less flexible scheduling.

CDL total cost breakdown:

CDL knowledge test: $10–$50 per attempt (state fee)
CLP issuance fee: $20–$75 (state fee)
CDL skills test: $50–$200 (state/third-party examiner fee)
CDL card issuance: $15–$75 (state fee)
DOT physical: $100–$200 (healthcare provider)
Training: $0 (employer-sponsored) to $10,000+ (private school)

CDL Endorsements

Endorsements are additions to your CDL that authorize you to drive specific vehicle types or haul specific cargo. Each endorsement requires passing an additional knowledge test, and some require an additional skills test or background check.

Common CDL endorsements:

H — Hazardous Materials: Required to haul HAZMAT cargo. Requires TSA background check and fingerprinting (not just a knowledge test). The H endorsement is the most complex to obtain but commands higher pay.
N — Tank Vehicles: Required for driving liquid or gas tank trucks
P — Passenger: Required for buses and passenger vehicles
S — School Bus: Required for school bus drivers (state background check also required)
T — Double/Triple Trailers: Required for pulling double or triple trailers
X — Tanker + Hazmat Combination: Combined N+H endorsement for liquid hazmat haulers
