Book your CDL appointment through your state's DMV website or by phone — the method and wait time depend on which state you live in

A Commercial Driver's License (CDL) appointment is a scheduled slot at your state's Department of Motor Vehicles where you take the written knowledge test, the skills test, or both. You cannot walk in to most DMV offices for CDL testing; you must reserve a time in advance. The process starts on your state DMV's website, where you'll find the appointment booking system, or by calling the local DMV office that handles CDL testing in your area.

Each state runs its own CDL program, so the steps and wait times vary. Some states let you book online weeks ahead; others require a phone call and may have a waiting list. A few states use third-party testing vendors instead of the DMV itself. Before you start, confirm which office in your state handles CDL appointments — not every DMV location offers CDL testing.

Key Takeaways

  • CDL appointments must be booked in advance through your state DMV's website or by phone; walk-ins are not accepted for CDL testing.
  • You will need your current valid driver's license, proof of residency, and a completed medical certificate (CDLIS Medical Examiner's Certificate) before you can test.
  • Wait times for CDL appointments range from a few days to several months depending on your state and the current testing backlog.
  • Some states allow you to take the written test and skills test on the same day; others require you to pass the written test first and schedule the skills test separately.
  • If your state uses a third-party testing vendor, you may book through that vendor's website instead of the DMV directly.

How to find your state's CDL appointment system

Start by visiting your state's official DMV website and searching for "CDL appointment" or "commercial driver's license testing." Most state DMV sites have a dedicated section for CDL applicants with a link to the booking system. If you cannot find it online, call your state DMV's main line and ask which office handles CDL testing in your county or region, then ask for that office's phone number.

A few states contract with third-party testing companies instead of handling CDL tests in-house. For example, some states use Pearson VUE or other vendors to administer the written test. If your state uses a vendor, the DMV website will direct you to that vendor's booking portal. Do not assume you can book through the DMV website if your state has outsourced testing.

What documents you need before booking

Have these documents ready before you call or go online to schedule:

  • A valid, non-commercial driver's license (your current state ID)
  • Proof of residency — a utility bill, lease, or bank statement with your current address
  • A completed CDLIS Medical Examiner's Certificate (also called a DOT medical certificate), signed by a certified medical examiner
  • Your Social Security number

The medical certificate is the document most people forget. You cannot take a CDL test without one. You must visit a medical examiner certified by the Federal Motor Carrier Safety Administration (FMCSA) to get this certificate; your regular doctor cannot issue it. The exam costs between $50 and $150 depending on the examiner. Once you have the certificate, it is valid for two years.

Booking online versus calling the DMV

If your state offers online booking, you can usually reserve a slot on the DMV website by entering your driver's license number, date of birth, and the type of test you need (written, skills, or both). Online booking often shows available dates weeks in advance and confirms your appointment when ready. This is the fastest route if it is available in your state.

If your state requires a phone call, call the DMV office that handles CDL testing during business hours. Have your driver's license, Social Security number, and medical certificate information ready. The staff will tell you the next available date and may place you on a waiting list if appointments are full. Some states with high demand have wait times of two to four months; others can schedule you within a week. Ask how long the current wait is before you call.

Wait times and what affects them

CDL appointment availability varies widely by state and season. States with large trucking industries — Texas, California, Florida — often have longer waits because more people are testing. Rural states with fewer applicants may have appointments available within days. Seasonal demand also matters: spring and summer typically see more CDL applicants, which pushes wait times longer.

If your state's wait time is longer than you expected, ask the DMV whether you can test in a neighboring state. Some states allow out-of-state residents to take the CDL test, though you will still need to get your license from your home state after you pass. This option works only if you live near a state border and that neighboring state has shorter wait times.

What to expect on test day

Arrive 15 minutes early with your appointment confirmation, valid driver's license, and medical certificate. The written test (also called the knowledge test) covers traffic laws, vehicle safety, and cargo handling. You answer 50 multiple-choice questions and must score at least 80 percent to pass. The test takes about one hour.

If you pass the written test, you may take the skills test the same day or schedule it separately, depending on your state's rules. The skills test includes a vehicle inspection, a backing exercise, and an on-road driving portion. It lasts 30 to 45 minutes. You must bring the same vehicle you will use for the test — the examiner will inspect it for safety equipment and proper maintenance.

Rescheduling or canceling your appointment

If you need to change your appointment date, contact the DMV office or testing vendor as soon as possible. Most states allow you to reschedule online or by phone without a fee, but policies vary. Some offices charge a small fee if you cancel within a certain number of days. A few states have a strict no-cancellation policy and will not refund or reschedule.

If you miss your appointment without canceling, you may lose your fee and have to book a new slot. Check your state's cancellation policy when you book so you know what happens if your plans change.

Frequently Asked Questions

Can I take the written and skills test on the same day?

It depends on your state. Some states allow you to take both tests in one visit if you pass the written test first. Others require you to pass the written test, wait a few days, and then schedule the skills test separately. Ask when you book your appointment whether same-day testing is an option.

What if I fail the written test?

You can retake the written test, but you must wait a set number of days before you can test again — usually between one and seven days depending on your state. You will need to book a new appointment and may have to pay the test fee again. Check your state's retake policy when you schedule.

Do I need to bring my own vehicle for the skills test?

Yes. The vehicle must be the same class as the CDL you are testing for (Class A, B, or C), and it must pass a safety inspection. The examiner will check brakes, lights, mirrors, and other equipment before the test begins. If the vehicle fails inspection, you cannot test that day.

What if my medical certificate expires before my test date?

You cannot test with an expired medical certificate. If your certificate will expire before your appointment, get a new one from a certified medical examiner before your test date. The new certificate takes effect when ready.

Can I book a CDL appointment in a different state than where I live?

Some states allow non-residents to test, but you will still need to get your CDL from your home state after you pass. Call the DMV office in the state where you want to test and ask whether they accept out-of-state applicants. You will need a valid driver's license from your home state and proof of residency there.
