What the Fontana Commercial DMV Office Does

The Fontana DMV office handles commercial driver's license (CDL) testing, renewals, and transactions for the San Bernardino County area. This is a full-service DMV location, not a satellite office, which means you can complete most commercial licensing work in one visit — though some transactions still require appointments or advance preparation.

The office processes CDL knowledge tests, skills tests (driving exams), license renewals, duplicate licenses, and medical certificate submissions. It also handles standard driver's license work if you need it, but the commercial side is what sets this location apart from smaller offices.

The Fontana location is one of the busier DMV offices in the region because it serves multiple counties and handles the volume of commercial drivers in the Inland Empire. This means wait times can be long, especially on Tuesdays through Thursdays and during mid-morning hours.

Key Takeaways

  • The Fontana DMV is a full-service office that administers CDL knowledge tests, skills tests, and renewals without requiring you to travel to a larger regional center.

  • Knowledge tests can often be taken without an appointment, but arriving early and checking current wait times online first will save you hours.
  • Bring your medical certificate (Form DL 51) and current license or ID; missing documents are the most common reason for delays.
  • The office is located at 16430 Slover Avenue, Fontana, CA 92337, and is open Monday through Friday, 8 a.m. to 5 p.m., with limited Saturday hours.

How to Schedule a Skills Test at Fontana

If you need to take a commercial driving skills test (the behind-the-wheel exam), you must book an appointment through the California DMV website at dmv.ca.gov or by calling 1-800-777-0133. You cannot walk in for a skills test, and the Fontana location typically has a wait of several weeks for available slots, especially during peak hiring seasons in the transportation and logistics industries.

When you schedule, have your learner's permit number or driver's license number ready, and know which class of CDL you are testing for (Class A, B, or C) and which endorsements you need (hazmat, tanker, doubles, passenger, etc.). The DMV will confirm your appointment time and provide instructions on what vehicle to bring and what documents to have with you.

Appointments fill up quickly in Fontana because the office serves a large geographic area. If the date you want is not available, you may see earlier slots at other regional offices like San Bernardino or Ontario, though those can also be booked weeks out. Check back frequently — cancellations do open up slots.

Knowledge Test Walk-Ins and Wait Times

The knowledge test (the written exam for your CDL permit) does not require an appointment at Fontana, but you should arrive early and expect to wait. The office typically has the longest waits between 10 a.m. and 2 p.m. on weekdays. Arriving right when the office opens at 8 a.m. or after 3 p.m. usually means shorter lines.

Before you go, check the DMV's real-time wait times at dmv.ca.gov/offices. The Fontana office publishes current wait estimates, and this information updates throughout the day. If the wait is over 90 minutes, consider coming back another day — the office is open Monday through Friday, 8 a.m. to 5 p.m., and Saturday hours vary by season.

Bring your current driver's license or ID, your Social Security number (or Individual Taxpayer Identification Number), and proof of residency. You will also need to pay the knowledge test fee, which varies depending on the class of license. The test is offered in multiple languages, and you can request a test in your preferred language when you arrive.

Documents You Need for Any CDL Transaction

The single most common reason for delays at the Fontana DMV is missing or incomplete documents. Before you go, gather everything on this list to avoid a wasted trip.

For a knowledge test, bring your current California driver's license or ID, proof of residency (utility bill, lease, or bank statement dated within 90 days), your Social Security number, and payment for the test fee. For a skills test, you need your valid CDL learner's permit, proof of residency, your medical certificate (Form DL 51 or a valid medical examiner's certificate), and the vehicle you will be testing in — it must be the same class and have the same endorsements you are testing for.

For a renewal, bring your current CDL, your medical certificate (required every two years for most commercial drivers), proof of residency, and payment for the renewal fee. If your medical certificate has expired, you cannot renew your CDL until you submit a new one. Many drivers miss this requirement and have to leave, get a medical exam, and return.

If you are explore for hazmat or other endorsements, bring any additional documents the DMV requests — these vary by endorsement type. Check your renewal notice or the DMV website for the specific list before you arrive.

Scam Alerts and Safety Information

Do not use third-party websites that claim to schedule DMV appointments or process CDL transactions for you. These sites charge fees and often provide incorrect information or fail to submit your request at all. The only official way to schedule is through dmv.ca.gov or by calling 1-800-777-0133.

Be cautious of anyone offering to take your skills test for you or claiming they can may provide you will pass. CDL testing is administered by DMV examiners, and no outside party can influence the outcome. If someone approaches you in the parking lot offering this service, report it to the DMV or local law enforcement.

Do not pay for a medical certificate through the DMV office itself — you must obtain it from a certified medical examiner before you arrive. The DMV only accepts certificates that are already completed. Some scammers pose as medical examiners and charge inflated fees; use the official list of certified examiners at dmv.ca.gov.

Protect your Social Security number and driver's license information. The DMV will never ask for these by email or phone. If you receive an email claiming to be from the DMV asking you to verify information or pay a fee, it is a phishing scam — delete it and report it to the California Attorney General's office.

Fees and Payment Methods at Fontana

CDL knowledge test fees, skills test fees, and renewal fees vary by license class and endorsement. As of the most recent update, knowledge tests range from around $15 to $35 depending on the class, and skills tests are typically $50 to $70. Renewal fees depend on your license class and how many years you are renewing for.

The Fontana DMV accepts cash, debit cards, and credit cards. Some transactions may have additional fees if you pay by card. Ask at the counter what payment methods are accepted for your specific transaction, as policies can change.

If you are renewing by mail or online (available for some CDL renewals), you may be able to pay by check or electronic transfer. Check the renewal notice that came with your current license for payment instructions.
