What the Rancho San Diego DMV offers for commercial driver's licenses

The Rancho San Diego Department of Motor Vehicles office handles commercial driver's license (CDL) testing and issuance for San Diego County residents. This location administers both the written knowledge test and the behind-the-wheel driving test required for a CDL. You cannot complete your entire CDL process at one visit — the written test and driving test are scheduled separately, and you must pass the written exam before you can take the driving test.

The Rancho San Diego office is located at 9350 Fuerte Drive, San Diego, CA 92126. It is open Monday through Friday, 8 a.m. to 5 p.m., and closed on state holidays. You will need to bring specific documents and pay the required fees at the time of your test. Appointments are strongly recommended because walk-in capacity is limited.

Key Takeaways

  • The Rancho San Diego DMV administers both the written knowledge test and the driving test for commercial driver's licenses, but you must schedule them separately.
  • You must pass the written test before the DMV will let you schedule a driving test appointment.
  • Bring your valid California driver's license, proof of residency, and the correct fee amount in cash or card to your appointment.
  • Book your appointment online through the California DMV website or by calling 1-800-777-0133 to avoid long wait times.

Documents and fees you need to bring

Before you arrive at the Rancho San Diego office, gather your current California driver's license, proof of residency (a utility bill, lease, or mortgage statement dated within the last 60 days), and your Social Security number or ITIN. If you are renewing a CDL rather than obtaining one for the first time, bring your current CDL as well.

The written test fee is $35. The driving test fee is $100. The CDL itself costs $70 if you are obtaining it for the first time, or $65 if you are renewing. Payment is accepted in cash or by debit or credit card. Bring exact change or be prepared to use a card, as the office may have limited ability to make change.

How to schedule your written test appointment

Go to the California DMV website at dmv.ca.gov and select "Schedule an Appointment." Choose the Rancho San Diego location, then select "Commercial Driver License Knowledge Test" from the service menu. The website will show available dates and times for the next several weeks. Book the earliest slot that works for your schedule.

If you cannot use the online system, call 1-800-777-0133 between 8 a.m. and 5 p.m., Monday through Friday. Have your driver's license number ready. The phone line can be busy during peak hours, so try calling early in the morning or late in the afternoon. You will receive a confirmation email or text with your appointment date, time, and a reminder of what to bring.

What to expect during the written knowledge test

The written test covers vehicle inspection, safe driving practices, and the rules of the road specific to commercial vehicles. The test has 50 questions, and you must answer at least 40 correctly to pass. You have 60 minutes to complete it. The test is offered in English and Spanish; select your language preference when you arrive.

Arrive 10 to 15 minutes early to allow time for check-in. Bring your appointment confirmation, valid driver's license, and proof of residency. You will not be allowed to bring phones, notes, or study materials into the testing room. If you fail the test, you can retake it, but you must pay the $35 fee again and schedule a new appointment. Most people who study the California CDL Handbook can pass on their first attempt.

Scheduling and taking the driving test

After you pass the written test, the DMV will give you a notice of passage. You must bring this notice when you schedule your driving test appointment. Use the same online booking system or phone number to schedule the driving test. The DMV typically has driving test slots available within two to four weeks of your written test date, though availability varies by season.

For the driving test, you must bring a vehicle that matches the class of CDL you are seeking — for example, a Class A vehicle (combination of tractor and trailer) for a Class A CDL. The vehicle must be registered, insured, and in safe working condition. The examiner will inspect the vehicle before the test begins. The driving test itself takes 30 to 45 minutes and includes a pre-trip inspection, basic vehicle control exercises, and on-road driving.

Different CDL classes and what they allow

California issues three classes of commercial driver's licenses: Class A, Class B, and Class C. A Class A CDL allows you to drive a combination of vehicles with a gross combined weight rating (GCWR) of 26,001 pounds or more, where the towed vehicle weighs more than 10,000 pounds. This is the most common CDL for truck drivers. A Class B CDL allows you to drive a single vehicle with a GCWR of 26,001 pounds or more, or a vehicle towing another vehicle weighing 10,000 pounds or less. A Class C CDL is for drivers of smaller commercial vehicles, such as buses or vehicles carrying hazardous materials.

You can also add endorsements to your CDL, such as a Hazmat endorsement (H) for transporting hazardous materials or a Passenger endorsement (P) for driving buses. Each endorsement requires an additional written test. The Rancho San Diego office administers endorsement tests as well.

What happens if you fail the driving test

If you do not pass the driving test on your first attempt, you will receive a written notice explaining which skills you did not demonstrate. You can retake the test, but you must schedule a new appointment and pay the $100 fee again. There is no waiting period between attempts, so you can book your next test when ready if slots are available. Most people pass on their second or third attempt after additional practice.

If you fail three times in a 12-month period, you must retake the written knowledge test before you can schedule another driving test. This rule exists to may support that drivers refresh their knowledge of traffic laws and vehicle safety. Keep your notice of passage from the written test in a safe place so you have it ready for your next driving test appointment.

Frequently Asked Questions

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

No. You must pass the written test first, receive your notice of passage, and then schedule the driving test separately. Most people schedule the driving test for two to four weeks after passing the written test to allow time for practice.

What if I move out of San Diego County after I pass the written test?

You can take your driving test at any California DMV office that offers CDL testing. Bring your notice of passage from the Rancho San Diego office to your new location. The notice is valid statewide.

Do I need to take a medical exam before getting a CDL?

Yes. You must obtain a medical certificate from a certified medical examiner and submit it to the DMV before your CDL is issued. The examiner checks your vision, hearing, and overall health. You can find a certified examiner through the National Registry of Certified Medical Examiners at fmcsa.dot.gov.

Can I renew my CDL by mail or online?

CDL renewals require an in-person visit to the DMV, including a new written test and medical certificate. You cannot renew a CDL entirely by mail or online. Schedule an appointment at Rancho San Diego or another DMV office at least 60 days before your CDL expires.

What if I have a suspended or revoked driver's license?

You cannot obtain a CDL if your regular driver's license is suspended or revoked. You must clear the suspension or revocation first by paying any fines, completing required programs, or waiting out the suspension period. Contact the DMV to find out the status of your license before you schedule a CDL test.
