Commercial Driver's License (CDL) Services at Fontana

If you need a commercial driver's license, the Fontana DMV office administers both the written knowledge test and the behind-the-wheel driving test. Before you schedule either test, you must obtain a valid medical certificate from a certified medical examiner and submit it to the DMV. This form, called a Medical Examiner's Certificate (Form DL 51), confirms you meet federal health standards for operating commercial vehicles. You cannot take the CDL tests without this certificate on file.

The written test covers federal and state regulations specific to the class of vehicle you plan to operate — Class A (tractor-trailers and heavy combinations), Class B (single large vehicles), or Class C (smaller commercial vehicles). You must pass this test before scheduling the behind-the-wheel exam. The driving test is conducted at the Fontana office and typically takes 30 to 45 minutes. You must bring your own commercial vehicle for the test, and it must be properly registered and insured.

If you already hold a CDL from another state, you can transfer it to California, but you must still pass the written test for California-specific regulations. The transfer process is faster than obtaining a new CDL from scratch.

Commercial Vehicle Registration and Plates

Commercial vehicle registration at the Fontana DMV follows the same basic steps as passenger vehicle registration, but the fees and plate types depend on your vehicle's gross vehicle weight rating (GVWR) and how you plan to use it. Vehicles over 10,000 pounds GVWR typically require commercial license plates and may be subject to additional registration fees. You will need your vehicle's title or proof of ownership, the vehicle identification number (VIN), and proof of current insurance.

If you are registering a vehicle for the first time in California, bring the out-of-state title or manufacturer's certificate of origin. If you are renewing commercial registration, you can often do this online or by mail, but changes to vehicle information or plate type require an in-person visit to the Fontana office. The office can also issue temporary registration permits if you need to operate the vehicle before your permanent plates arrive.

Documents You Need for Commercial Services

The specific documents required depend on your transaction type, but most commercial services at Fontana require a core set of items. Bring your current California driver's license or identification card, proof of California residency (such as a utility bill or lease dated within the last 60 days), and your Social Security number or ITIN. For CDL services, add your medical certificate and any current commercial endorsement documents from other states.

For commercial vehicle registration, bring the vehicle's title or proof of ownership, the VIN, proof of insurance, and the vehicle registration form (Form REG 343 if renewing, or Form REG 343 for new registration). If you are registering a vehicle for commercial use but have not yet obtained a CDL, you can still register the vehicle — the registration and the license are separate transactions. However, you cannot legally operate a commercial vehicle without both the proper registration and a valid CDL.

Hours, Appointments, and Wait Times at Fontana

The Fontana DMV office is open Monday through Friday, 8:00 a.m. to 5:00 p.m., and closed on state holidays. Saturday and Sunday hours are not available at this location. You can reserve a time slot online at dmv.ca.gov up to 60 days in advance, which typically reduces your wait time to 15 to 30 minutes. Walk-in customers are served on a first-come, first-served basis, and wait times can exceed two hours during peak periods (mid-morning and early afternoon on weekdays).

Commercial services, particularly CDL testing, often have longer wait times than standard registration renewals because each test must be administered individually. If you are scheduling a behind-the-wheel CDL test, the office may have limited availability, and you may need to book several weeks in advance. Calling the Fontana office at (909) 350-3100 can help you confirm current wait times and appointment availability before you visit.

What Happens After You Complete Your Transaction

If you pass a CDL written test, you will receive a temporary permit valid for 180 days while you schedule and take the behind-the-wheel exam. Once you pass both tests, your CDL will be mailed to your address on file within 10 to 14 business days. If you fail either test, you can retake it, but you must wait at least one day before retesting.

For commercial vehicle registration, temporary registration permits are issued when ready if you need them, and your permanent plates will arrive by mail within 10 to 15 business days. If you are renewing an existing commercial registration, your new registration card and plates will be mailed to you. Keep your temporary permit in the vehicle until the permanent plates arrive.

Common Issues and How to Avoid Them

The most frequent reason for delays at the Fontana DMV is an expired or missing medical certificate for CDL applicants. Medical certificates are valid for 24 months, and you must renew yours before it expires or your CDL will be suspended. Check your certificate's expiration date before you schedule any CDL test or renewal.

Another common issue is bringing a vehicle to the behind-the-wheel test that does not meet safety requirements. Your vehicle must have working brakes, lights, wipers, and mirrors, and it must be properly registered and insured. If the examiner finds safety defects, the test will be cancelled and you will lose your appointment slot. Inspect your vehicle thoroughly before you arrive.

For commercial registration, mismatched vehicle information (VIN, title, and registration form) can delay processing. Double-check that all numbers match before you submit your documents. If you are unsure whether your vehicle qualifies as commercial, ask the staff at the Fontana office — registering a vehicle under the wrong category can create problems later.

Frequently Asked Questions

Do I need an appointment to visit the Fontana DMV for commercial services?

Appointments are not required, but they are strongly recommended. You can reserve a time slot online at dmv.ca.gov up to 60 days in advance, which typically reduces your wait time significantly. Walk-ins are accepted during business hours on a first-come, first-served basis.

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

No. You must pass the written test first, then schedule the behind-the-wheel test separately. Most people schedule the driving test for a different day to allow time to prepare. Some applicants wait a few days between tests; others schedule them weeks apart.

What if my medical certificate expires before my CDL renewal date?

Your CDL will be suspended if your medical certificate expires. You must obtain a new medical certificate from a certified examiner and submit it to the DMV before your current one expires. You can renew your medical certificate at any time — you do not have to wait until your CDL renewal date.

Can I register a commercial vehicle if I do not yet have a commercial driver's license?

Yes. Vehicle registration and driver licensing are separate processes. You can register a commercial vehicle without a CDL, but you cannot legally operate it on public roads without one. Make sure you obtain your CDL before you use the vehicle for commercial purposes.

How long does it take to get my commercial license plates after registration?

Permanent commercial plates are typically mailed to your address within 10 to 15 business days after your registration is processed. The Fontana office can issue temporary registration permits when ready if you need to operate the vehicle before the permanent plates arrive.
