The Fontana Commercial DMV serves San Bernardino County businesses and commercial vehicle owners

The Fontana office is a California Department of Motor Vehicles location that handles commercial vehicle registration, commercial driver's license (CDL) testing and renewal, and business-related vehicle transactions. It is located in Fontana, California, in San Bernardino County. This office does not handle standard passenger vehicle services — those go to the regular DMV office also in Fontana or to other county locations.

If you own a commercial truck, operate a fleet, or need a CDL, you will likely work with this office at some point. The office processes heavy truck registrations, commercial vehicle inspections, and CDL written and behind-the-wheel tests. Wait times and service speed vary by time of day and season.

You do not need an appointment for most services, but the DMV website shows current wait times by location and service type. Checking before you go saves time, especially during peak hours (typically mid-morning and early afternoon on weekdays).

What services the Fontana Commercial DMV provides

The Fontana Commercial DMV handles commercial vehicle registration and renewal for trucks, buses, and other vehicles over a certain weight threshold. This includes registering new commercial vehicles, renewing existing registrations, and updating registration information. The office also processes commercial vehicle title transfers and handles smog check clearances for commercial vehicles.

Commercial driver's license (CDL) services are a major function of this office. You can take the CDL written test (the knowledge test) here, and the office coordinates behind-the-wheel testing for Class A, B, and C commercial licenses. The office also handles CDL renewals, medical certificate reviews, and endorsement additions (such as hazmat or passenger endorsements).

Fleet owners and commercial operators can handle bulk registration renewals and address changes at this location. If you operate multiple vehicles under a business license, this office can process several transactions in one visit, though processing time increases with the number of vehicles.

Documents you will need to bring

For commercial vehicle registration or renewal, bring your current vehicle registration card, proof of insurance (the insurance company's declaration page or ID card), and a valid government-issued ID. If the vehicle has not passed smog check, bring the smog check certificate or clearance notice. For a new commercial vehicle registration, bring the title or manufacturer's certificate of origin.

For CDL written tests, bring your current driver's license, proof of California residency (utility bill, lease, or bank statement dated within the last 60 days), and your medical certificate if you are renewing a CDL. If you are taking a behind-the-wheel test, bring the same documents plus proof of insurance for the vehicle you will be tested in.

For any transaction involving a business, bring documentation showing your business name and ownership — a business license, articles of incorporation, or partnership agreement. If someone else is handling the transaction on your behalf, bring a signed power of attorney or notarized authorization letter.

How to find the office location and hours

The Fontana Commercial DMV is located in Fontana, San Bernardino County. The exact street address, phone number, and current hours are on the California DMV website under "Find a Field Office." Search for "Fontana" and select the commercial office from the results. Hours vary by location and may change seasonally, so confirm before you go.

The office is typically open Monday through Friday during standard business hours. Some DMV locations offer limited Saturday service, but the Fontana Commercial office may not — check the website or call ahead. The DMV website also shows real-time wait times by service type, updated throughout the day.

If you cannot visit in person, some transactions (such as registration renewal) can be completed by mail or through the California DMV website if you meet certain conditions. The DMV website explains which services are available online and which require an in-person visit.

Wait times and how to minimize them

Wait times at the Fontana Commercial DMV vary by service and time of day. Commercial vehicle services and CDL testing typically have longer waits than standard passenger services because they require more staff time and documentation review. Peak times are usually mid-morning (9 a.m. to 11 a.m.) and early afternoon (1 p.m. to 3 p.m.) on weekdays.

The California DMV website displays current wait times by location and service type, updated every 30 minutes or so. Check the website before you leave home — if the wait is over 30 minutes, consider going at a different time or on a different day. Early morning (right when the office opens) and late afternoon (after 3 p.m.) typically have shorter waits.

Taking a number when you arrive is standard at DMV offices. The office will call your number when a representative is ready. Do not leave the office while waiting — if your number is called and you are not present, you may lose your place in line.

Scams and safety information

Do not pay for DMV services through third-party websites or apps that claim to speed up your transaction. The only official way to conduct DMV business is in person at an office, by mail, or through the official California DMV website (dmv.ca.gov). Any other site charging a fee for DMV services is not legitimate.

Be cautious of people offering to handle your DMV transaction for you in the parking lot or outside the office. These are often scams designed to steal your documents or money. Always conduct DMV business directly with DMV staff inside the office.

If someone calls claiming to be from the DMV and asks for payment or personal information, hang up. The DMV does not initiate contact by phone to collect fees or verify identity. If you are unsure whether a notice is real, call the DMV directly using the number on the official website — do not use a number from an email or letter you received.

What to do if you cannot visit in person

Some commercial vehicle services require an in-person visit, but others can be handled by mail or online. Commercial vehicle registration renewal can often be completed through the California DMV website if your vehicle has passed smog check and your insurance is current. CDL tests must be taken in person at a DMV office.

If you need to renew your commercial vehicle registration by mail, read the renewal notice from the DMV website or use the notice you received in the mail. Fill it out, include payment, and mail it to the address on the form. Processing by mail typically takes two to three weeks.

If you cannot take your CDL test on a specific date, contact the Fontana Commercial DMV office directly to ask about rescheduling. Some offices allow you to reschedule online or by phone, while others require you to visit in person. Call ahead to find out the process.

Frequently Asked Questions

Do I need an appointment to visit the Fontana Commercial DMV?

Most services do not require an appointment — you arrive, take a number, and wait for your turn. However, some CDL behind-the-wheel tests may need to be scheduled in advance, especially during busy seasons. Call the office or check the DMV website to confirm whether your specific service requires an appointment.

Can I renew my commercial vehicle registration online?

You may be able to renew online through the California DMV website if your vehicle has passed smog check, your insurance is current, and you have no outstanding violations or fees. If any of these conditions are not met, you will need to visit the office in person or mail in your renewal.

How long does a CDL written test take?

The CDL written test typically takes 30 minutes to one hour to complete, depending on the number of endorsements you are testing for. After you finish, the DMV scores the test when ready and tells you whether you passed. If you pass, you can schedule your behind-the-wheel test at that time.

What if I fail my CDL behind-the-wheel test?

If you fail, you can retake the test, but you must wait at least two days before your next attempt. You do not need to retake the written test unless your knowledge certificate has expired. Contact the Fontana Commercial DMV office to schedule your next behind-the-wheel test.

Is there parking at the Fontana Commercial DMV office?

Most DMV offices have parking available, but it may be limited during peak hours. Arrive early if possible. If you cannot find parking nearby, consider visiting at a less busy time or checking whether your transaction can be completed online or by mail instead.
