What the Fontana DMV office handles for commercial vehicles
The Fontana DMV office processes commercial vehicle registrations, renewals, and related transactions for the San Bernardino County area. You can register a commercial truck, obtain a commercial driver's license (CDL), renew commercial plates, and handle certain commercial vehicle inspections at this location. The office does not handle all commercial services — some require a visit to a larger regional office or completion of paperwork by mail.
Fontana is one of several DMV locations in San Bernardino County, so depending on your specific need, you may have options about where to go. The Fontana office is located at 16570 Slover Avenue and operates during standard DMV hours, though hours vary by day and change seasonally.
Key Takeaways
- The Fontana DMV handles commercial vehicle registration, CDL testing, and commercial plate renewals, but you should confirm your specific transaction is available there before making the trip.
- You will need your current registration, proof of insurance, and a valid ID for most commercial transactions; commercial trucks may require a smog certificate or brake inspection.
- Commercial vehicle registration in California requires proof that your vehicle meets weight and safety standards, which varies by the truck's gross vehicle weight rating (GVWR).
- The Fontana office uses appointment slots during peak hours, so arriving without one may mean a longer wait or being turned away if capacity is full.
- Some commercial services, such as certain commercial vehicle inspections or specialized endorsements, may only be available at the San Bernardino main office or require submission by mail.
Commercial vehicle registration requirements at Fontana
To register a commercial vehicle at the Fontana DMV, you need your current registration document (if renewing), proof of California insurance, and a valid government-issued ID. If your vehicle is new to California or you are registering it for the first time, bring the manufacturer's certificate of origin or the out-of-state title.
Commercial trucks over a certain weight threshold require a smog certificate or, in some cases, a brake inspection certificate. The requirement depends on your vehicle's gross vehicle weight rating (GVWR) and age. Vehicles registered as commercial are subject to different fee structures than personal vehicles, and the registration cost varies based on weight and use classification.
If you are registering a vehicle for commercial use but it was previously registered as personal, you will need to change the registration type. This requires the same documents as a new registration plus your previous registration documents.
Commercial driver's license (CDL) testing and renewal
The Fontana DMV administers CDL written tests and renewal appointments. If you are seeking a CDL for the first time, you must pass a written knowledge test before scheduling a behind-the-wheel driving test. The written test covers general knowledge, air brakes, and any endorsements you are pursuing (such as hazmat or tanker).
Bring your current driver's license, proof of residency, medical certification (MCSA-5871 form), and any documents related to the endorsement you are pursuing. The medical certificate must be current and signed by a certified medical examiner. If you are renewing a CDL, bring your current license and the same medical certification.
Behind-the-wheel CDL tests are scheduled separately and may not be available at the Fontana location for all vehicle classes. Confirm with the office whether your specific test type is offered there, as some tests are only administered at larger regional facilities.
Commercial plate renewals and address changes
Renewing commercial plates at Fontana is straightforward if your vehicle information has not changed. Bring your current registration, proof of insurance, and your ID. If your registration has expired, you may face late fees depending on how long it has been expired.
If you have moved and need to update your address on a commercial registration, bring the same documents plus proof of your new address (utility bill, lease, or mortgage statement dated within the last 60 days). Address changes can usually be processed at the same time as a renewal.
Commercial vehicle registrations in California are typically valid for one or two years, depending on the vehicle type and weight. The renewal date is printed on your registration card. Some commercial vehicles are subject to annual smog checks, so confirm whether your vehicle requires one before your renewal date.
Making an appointment and what to expect
The Fontana DMV office operates on an appointment system during busy periods. You can schedule an appointment through the California DMV website or by calling the office directly. Walk-ins are accepted during slower hours, but you may experience a wait or be turned away if the office reaches capacity.
Appointment slots for commercial services often fill quickly, especially for CDL testing. If the Fontana location has no available slots, you can check availability at other San Bernardino County offices or the main San Bernardino DMV office. Some transactions, such as certain commercial inspections, may only be available at the main office.
Bring all required documents in original form or certified copies. The DMV does not accept photocopies of titles, registrations, or medical certificates. Plan to spend 30 minutes to an hour at the office, depending on the complexity of your transaction and current wait times.
When to go to the San Bernardino main DMV instead
Some commercial vehicle services are only available at the San Bernardino DMV main office, located downtown. These include certain commercial vehicle inspections, specialized CDL endorsements that require additional testing, and some commercial fleet services. If the Fontana office tells you they cannot process your transaction, ask whether the main office can handle it and whether you need an appointment there.
The main office also handles commercial vehicle registration for vehicles with unusual classifications or those requiring regulatory review. If your vehicle does not fit standard registration categories, you may need to start there rather than at Fontana.

Frequently Asked Questions
Can I renew my commercial registration by mail or online?
Some commercial registrations can be renewed by mail if your vehicle information has not changed and you do not need a smog check. The DMV website shows whether your specific vehicle is may be able to access for mail renewal. If you are unsure, call the Fontana office before making the trip.
What if my commercial vehicle fails a smog check?
You cannot register the vehicle until it passes. You will need to have the vehicle repaired and retested by a smog station, then bring the passing certificate to the DMV. Some repairs are covered under California's smog abatement program if the vehicle is within a certain age range.
Do I need a CDL to drive a commercial truck in California?
Yes, if the truck's gross vehicle weight rating (GVWR) is 26,001 pounds or more, you must have a CDL. Trucks under that weight may be driven with a regular driver's license, though they still require commercial registration. Check your vehicle's specifications to confirm the GVWR.
How long does a CDL medical certificate last?
A medical certificate is valid for 24 months from the date it is signed by the medical examiner. You must renew it before it expires to keep your CDL valid. The DMV will not process a CDL renewal or issue a new CDL without a current medical certificate.
What happens if I let my commercial registration expire?
You cannot legally operate the vehicle on public roads. Late fees explore based on how long the registration has been expired. If it has been expired for more than a few months, you may need to pay penalties in addition to the renewal fee. Bring proof of insurance and your ID when you renew.
