CDL Classes: A, B, and C
Your CDL class determines what vehicles you can drive. Most truckers need a Class A.
Class A
The Standard for Trucking
What you can drive: Any combination of vehicles with a GCWR of 26,001+ lbs, where the towed unit is over 10,001 lbs
- Tractor-trailers (semi-trucks)
- Flatbeds, tankers, reefers
- Truck and trailer combinations
- Also covers everything in Class B and C
Median pay: $50,000–$80,000/year
Class B
Straight Trucks & Buses
What you can drive: Single vehicles with a GVWR of 26,001+ lbs, or towing a unit under 10,001 lbs
- Dump trucks, cement mixers
- Large buses (school, transit, tour)
- Box trucks, delivery trucks
- Garbage trucks, tanker trucks (non-combo)
Median pay: $40,000–$60,000/year
Class C
Specialized Vehicles
What you can drive: Vehicles not covered by A or B that carry 16+ passengers or haul hazmat
- Small passenger vans (16+)
- Hazmat vehicles under 26,001 lbs
- Small school buses
- Some specialty vehicles
Median pay: $35,000–$50,000/year
CDL Endorsements
Endorsements add capabilities to your CDL. Some are required by law for certain cargo or vehicles. Others open up higher-paying freight.
| Code | Endorsement | What It Covers | How to Get It | Pay Impact |
|---|---|---|---|---|
| H | Hazmat | Hazardous materials (fuel, chemicals, explosives) | Written test + TSA background check ($86.50) | +$5K-15K/yr |
| N | Tanker | Liquid bulk cargo in tanker vehicles | Written test only | +$3K-8K/yr |
| X | Hazmat + Tanker | Hazmat in tanker vehicles (fuel haulers) | Both H and N tests + TSA check | +$8K-20K/yr |
| T | Double/Triple Trailers | Pulling double or triple trailer combinations | Written test only | +$2K-5K/yr |
| P | Passenger | Vehicles carrying 16+ passengers | Written test + skills test | Varies |
| S | School Bus | School bus with passengers | Written test + skills test + background | $35K-50K/yr |
Pro tip: Get your Hazmat endorsement early, even if you don’t plan to haul hazmat right away. The TSA background check takes 2-4 weeks. Having it on your CDL opens doors to higher-paying loads when you’re ready.
How to Get Your CDL: Step by Step
Step 1
Get Your DOT Medical Card
Before anything else, pass the DOT physical exam. Visit a FMCSA-listed medical examiner (National Registry). Cost: $75-$200. Card is valid for 2 years (1 year if you have certain conditions).
You’ll need to pass vision (20/40), hearing, blood pressure (under 140/90 for 2-year card), and general health screening. See our Trucker Health Guide for full details.
Step 2
Get Your CDL Learner’s Permit (CLP)
Visit your state DMV with your medical card, ID, and social security card. Pass the CDL knowledge tests (general knowledge + air brakes + combination vehicles for Class A).
Cost: $10-$100 depending on state. Study the CDL manual — it’s free on your state DMV website. Most people pass with 1-2 weeks of study.
Step 3
Complete ELDT Training
Since February 2022, FMCSA requires Entry-Level Driver Training (ELDT) from a registered provider. This is the biggest step — and the biggest cost.
Training includes classroom instruction (theory) and behind-the-wheel training (BTW). Your training provider must be on the FMCSA Training Provider Registry (TPR). No exceptions.
Step 4
Pass the CDL Skills Test
Three parts: pre-trip inspection (you explain every component), basic controls (straight back, offset, parallel park, alley dock), and road test (drive on public roads with an examiner).
Cost: $100-$300 depending on state and whether you use a third-party testing site. Many CDL schools include the test in their program.
Step 5
Get Your CDL
Pass all three skills tests and your DMV issues your CDL. You’re officially a commercial driver.
Your CDL is valid for 4-8 years depending on state. Hazmat endorsement requires TSA renewal every 5 years. Medical card renewal every 2 years.

How to Pass the CDL Test
Pre-Trip Inspection
What it is: Walk around the truck, identify and explain every component, check for defects.
Duration: 30-45 minutes
How to pass:
- Memorize a consistent route around the truck
- Practice out loud — you have to verbalize everything
- Don’t skip components, even if they look fine
- Know the acronyms (GOALS, CLAMS, etc.) your school teaches
Fail rate: ~20%. Most common mistake: forgetting components under the hood.
Basic Controls
What it is: Maneuver the truck in a controlled area — straight back, offset back, alley dock (90-degree back into a space).
Duration: 15-30 minutes
How to pass:
- Use your mirrors — don’t lean out the window
- GOAL: Get Out And Look. Do it. No penalty for looking.
- Go slow — there’s no time limit
- Pull-ups are OK (limited). Encroachments fail you.
Fail rate: ~15%. Most fail on alley dock (90-degree backing).
Road Test
What it is: Drive on public roads with an examiner. Turns, lane changes, intersections, railroad crossings, highway driving.
Duration: 30-60 minutes
How to pass:
- Smooth and controlled — no jerky movements
- Proper scanning pattern (mirrors every 5-8 seconds)
- Signal early, check mirrors before lane changes
- Don’t hit curbs on right turns (biggest fail point)
Fail rate: ~30%. Most common: right turn curb strikes and improper scanning.
After Your CDL: What Comes Next
Company Driver (Start Here)
Most new CDL holders start as company drivers. 1-2 years of experience is the standard before going owner-operator. You’ll learn the business, build your record, and get paid while doing it.
- No truck to buy or insure
- Company handles permits, compliance, ELD
- Build driving record and miles
- Average: $50K-$70K first year
Owner-Operator (After Experience)
After 1-2 years, you can buy/lease a truck and run your own business. Higher earning potential but much more responsibility — including your own insurance.
- You buy the truck ($40K-$180K)
- You carry your own insurance ($12K-$25K/year)
- You handle compliance, permits, taxes
- Average: $60K-$120K+ depending on freight
The Insurance Connection
CDL experience directly affects your insurance rate. New CDL holders (under 2 years) pay significantly more for commercial auto insurance — often 30-50% more than experienced drivers. Every year of clean driving brings your premium down.
Endorsements affect your premium. Hazmat endorsement means hauling higher-risk cargo — your cargo and liability insurance will reflect that. Tanker endorsement similarly. The extra endorsement pay usually far outweighs the insurance increase.
Your driving record starts the day you get your CDL. Every accident, violation, and inspection goes on your record. CSA scores follow you. Protect your record from day one — it’s the single biggest factor in your insurance cost for years to come.

Frequently Asked Questions
How long does it take to get a CDL from start to finish?
Typically 4-10 weeks: 1 week to get your CLP (study and test), 3-8 weeks of ELDT training, and 1-2 days for the skills test. Company-sponsored programs can be faster (3-4 weeks). Community college programs run longer (8-16 weeks) but are more thorough. If you need a hazmat endorsement, add 2-4 weeks for the TSA background check.
Can I get a CDL with a DUI on my record?
It depends on when and how many. A single DUI in a personal vehicle from more than 3-5 years ago usually won’t prevent you from getting a CDL, but it will affect your employment and insurance options significantly. A DUI while holding a CDL results in a 1-year CDL disqualification (first offense) or lifetime disqualification (second offense). Check your state’s specific rules.
Is company-sponsored CDL training really free?
Free upfront, but not free of obligations. You commit to driving for that company for 1-2 years. If you leave early, you owe the training cost back ($3,000-$7,000). Starting pay is often lower during the commitment period. It’s a loan disguised as a benefit — which doesn’t make it bad, just understand what you’re agreeing to.
When should I go from company driver to owner-operator?
Most experts recommend at least 2 years of company driving before going owner-operator. You’ll need clean driving experience (insurers require it), savings ($15K-$30K minimum), understanding of freight markets, and ideally some relationships with brokers or shippers. See our Company Driver vs Owner-Operator guide for the full breakdown.
