What a CDL truck driving job requires

A Commercial Driver's License (CDL) is a separate license class that lets you operate trucks over 26,000 pounds gross vehicle weight rating (GVWR), buses carrying 16 or more passengers, or vehicles carrying hazardous materials. You cannot get a truck driving job that requires a CDL without holding one — it is a legal requirement, not optional training.

The CDL itself is not a job. It is a credential you earn from your state's Department of Motor Vehicles that proves you have passed written knowledge tests and a behind-the-wheel driving test. Once you hold a CDL, you can then search for and explore to truck driving positions with carriers, owner-operators, or freight companies.

Most truck driving jobs also require a medical certificate from a Department of Transportation (DOT) medical examiner. This certificate confirms you meet vision, hearing, and health standards set by federal law. You will need this before you can legally drive a commercial vehicle, even after you pass your CDL test.

Key Takeaways

  • A CDL requires passing a written test on traffic law and vehicle operation, then a practical driving test in a truck — you cannot skip either one.
  • Most states require you to hold a valid CDL permit for at least 14 days before you can take the driving test, so the process takes weeks, not days.
  • You will need a DOT medical certificate from a certified examiner before any employer will hire you to drive commercially.
  • Truck driving jobs vary widely in pay, schedule, and location — local delivery, regional routes, and long-haul over-the-road work have different demands and earnings.
  • Some employers offer paid CDL training programs where they cover tuition in exchange for a commitment to work for them after you pass your test.

Steps to get your CDL

Start by getting your CDL permit from your state's DMV. You will need your current driver's license, proof of residency, and proof of Social Security number. You then take a written test covering traffic laws, vehicle operation, and safety rules specific to commercial driving. The test is multiple choice and covers topics like braking, load securement, and hazmat regulations. Your state's CDL manual — available free online from your DMV — contains all the material you need to study.

After you pass the written test, you hold a CDL permit. Most states require you to wait at least 14 days before you can take the driving test, though some states have no waiting period. During this time, you can practice driving a commercial vehicle with a licensed CDL holder in the passenger seat.

Next comes the practical driving test, also called the skills test. You will perform a pre-trip inspection (walking around the truck and checking lights, brakes, and tires), a backing exercise (reversing the truck in a straight line or into a space), and an on-road drive lasting 30 to 60 minutes. You must pass all three parts. If you fail any section, you can retake just that section in most states, though rules vary.

Once you pass, your state issues your CDL. The card itself arrives in the mail within a few weeks. You can then legally drive a commercial vehicle — but you still need that DOT medical certificate before an employer will hire you.

Getting your DOT medical certificate

A DOT medical certificate is a form signed by a certified medical examiner confirming you meet federal health and vision standards. You cannot drive commercially without one. The exam checks your vision (at least 20/40 in each eye with or without correction), hearing, blood pressure, and general health. You will be asked about medications, sleep apnea, diabetes, and other conditions that affect driving safety.

Find a certified DOT medical examiner through the National Registry of Certified Medical Examiners on the Federal Motor Carrier Safety Administration (FMCSA) website. Search by your state and zip code. The exam costs between $100 and $200 depending on the examiner and your location. Your insurance does not cover it.

The certificate is valid for two years. Some examiners issue a one-year certificate if they have concerns about a condition but want to monitor it. You will need to renew it before it expires if you want to keep driving commercially.

CDL training programs and costs

You can study for your CDL on your own using your state's manual and practice tests, then take the written and driving tests at your DMV. This route costs only the DMV test fees, which range from $50 to $200 depending on your state and the number of endorsements you test for.

Many people attend a CDL training school instead. These are private programs lasting 3 to 8 weeks that teach vehicle operation, safety, and test preparation in a classroom and behind the wheel. Tuition ranges widely — from $3,000 to $15,000 or more — depending on the school, location, and program length. Some schools offer financing or payment plans.

Many trucking companies offer paid CDL training where they cover tuition costs in exchange for a commitment to work for them after you pass your test. The commitment is usually 1 to 2 years. If you leave before the commitment ends, you may owe back tuition. These programs are common with large carriers and can be a way to avoid upfront costs, but read the contract carefully before signing.

Types of truck driving jobs and what they pay

Truck driving jobs fall into a few main categories. Local delivery means you pick up and drop off freight within a region, usually returning home each night. Pay is often hourly and ranges widely by company and region. Regional driving covers a multi-state area and usually involves 2 to 4 nights away per week. Long-haul or over-the-road (OTR) driving means you are away from home for weeks at a time, covering thousands of miles across the country.

Pay structures vary. Some companies pay by the mile (typically 30 to 50 cents per mile for newer drivers), others by the hour, and some use a combination. Long-haul drivers often earn more per mile than local drivers, but they spend more on food and lodging on the road. Local drivers may earn less per mile but work more predictable hours and sleep at home.

Factors that affect pay include your experience, the type of freight (hazmat and tanker loads often pay more), your driving record, and the company. Starting pay for a new CDL holder is usually lower than for experienced drivers. Many drivers see their pay increase after their first year or two on the job.

Finding truck driving jobs after you get your CDL

Once you have your CDL and DOT medical certificate, you can search for jobs on general job boards like Indeed, LinkedIn, and Glassdoor by searching "CDL truck driver" or "commercial driver." You can also search directly on trucking company websites — large carriers like Swift, Werner, Schneider, and J.B. Hunt post openings on their careers pages.

Smaller local trucking companies, freight brokers, and owner-operators often hire through local job boards or word of mouth. Ask at truck stops or contact local logistics companies in your area. Some drivers find work through trucking-specific job boards like TruckersReport or Trucking Truth.

Your driving record matters. Most companies require a clean record with no major violations in the past 3 to 5 years. Some will hire drivers with minor violations or accidents, but at higher insurance rates or lower pay. Be honest about your history when you explore — companies run background checks and will find it anyway.

When you explore, have your CDL number, medical certificate, and driving history ready. Many companies require a pre-employment drug test. Some also require a physical ability test to confirm you can safely perform the job.

Endorsements and additional certifications

Your basic CDL lets you drive most trucks, but certain cargo requires additional endorsements on your license. A Hazmat (H) endorsement lets you carry hazardous materials and requires passing an additional written test and a background check. A Tanker (T) endorsement is needed to haul liquids in tank trailers. A Passenger (P) endorsement is required to drive buses.

These endorsements are optional — you do not need them to get a basic truck driving job. But they can open up higher-paying positions. Hazmat drivers, for example, often earn more than drivers without the endorsement. If your employer needs you to have an endorsement, they may cover the cost of the test and training.

Some employers also require or prefer additional certifications like FMCSA training (Hazmat safety), TWIC cards (for port access), or ELDT training (Entry-Level Driver Training, now required for new CDL holders in most states). Ask potential employers what certifications they require before you explore.

Frequently Asked Questions

Can I get a CDL if I have a DUI or traffic violations?

A DUI does not automatically disqualify you from getting a CDL, but it makes it harder. You can still take the written and driving tests. However, most trucking companies will not hire you with a DUI on your record, especially if it is recent. Some companies will hire drivers with older violations or minor infractions, but at lower pay or with restrictions.

How long does it take to get a CDL from start to finish?

If you study on your own, the process takes 2 to 4 weeks — you need at least 14 days between your permit and driving test in most states, plus time to study and schedule tests. If you attend a training school, add 3 to 8 weeks. Getting your DOT medical certificate can happen in parallel and usually takes a few days to a week to schedule.

Do I need to own a truck to drive commercially?

No. Most truck drivers work for trucking companies or freight carriers that own the trucks. Owner-operators own their own trucks and contract with shippers or brokers, but this requires significant capital and business knowledge. As a new driver, you will almost certainly work for a company that provides the truck.

What is the difference between a CDL and a regular driver's license?

A regular driver's license lets you drive passenger vehicles and light trucks under 26,000 pounds. A CDL is required to drive heavier commercial vehicles, buses, or vehicles carrying hazmat. You cannot legally drive a truck that requires a CDL with only a regular license, even if you are experienced.

Can I get a CDL if I am not a U.S. citizen?

Requirements vary by state. Most states require you to be a U.S. citizen or permanent resident to get a CDL. Some states allow other visa holders. Check with your state's DMV about what documents you need. You will need a valid Social Security number or Individual Taxpayer Identification Number (ITIN) in most cases.
