The Mandatory Actions Unit enforces DMV rules when you miss a important date or don't respond to a notice
The Mandatory Actions Unit (MAU) is a division of the California DMV that takes action when you don't comply with a DMV requirement by the important date given. This is not a penalty division — it exists to enforce rules that protect public safety, like keeping your license valid or reporting a change in your medical condition. If you receive a letter from the MAU, it means you missed a important date the DMV set, and the unit is now moving forward with consequences unless you act.
The MAU handles situations like failing to renew your license before it expires, not responding to a medical evaluation request, or not paying a traffic fine that triggered a license suspension. The unit does not make judgment calls about whether you had a good reason — it follows the law. Your job is to understand what action they want, what the important date is, and what happens if you do not meet it.
Key Takeaways
- The Mandatory Actions Unit sends you a letter when you have not met a DMV important date, such as renewing your license or responding to a medical evaluation request.
- The letter will state exactly what action you must take and by what date, and what will happen if you do not comply.
- Common MAU actions include license suspension for non-renewal, suspension for medical reasons, and suspension for unpaid traffic fines or court orders.
- If you ignore a MAU letter, your license will be suspended or revoked, and you cannot legally drive in California or any other state.
- You can contact the MAU directly to ask for more time, explain a hardship, or request a hearing before suspension takes effect.
Why the MAU sends you a letter in the first place
The DMV sends a MAU letter when you have not done something the law requires by the important date the DMV gave you. The most common reasons are: your license expired and you did not renew it; the DMV asked you to take a medical evaluation and you did not show up or respond; you owe a traffic fine or have an unpaid court order; or you did not report a change in your address or medical status that the law requires you to report.
The MAU does not decide whether your reason for missing the important date was valid. The unit's job is to enforce the important date. If you had a legitimate reason — you were hospitalized, you did not receive the letter, you were out of the country — you can explain that when you contact the MAU or request a hearing, but the letter itself is not the place to argue. The letter is a notice that you are out of compliance and what will happen next.
What the letter tells you and what you need to do when ready
A MAU letter will include: the specific action you failed to take; the original important date you missed; a new important date to comply (usually 10 to 30 days from the letter date); what will happen if you do not meet the new important date (usually license suspension or revocation); and instructions on how to comply. Read the entire letter carefully, because the action required may not be what you think.
Do not assume you know what the letter is about. Open it, read it completely, and identify the exact action the MAU wants. If the letter says "submit a medical evaluation report by [date]," you must obtain that report and send it — not just call the DMV to say you will do it. If it says "pay the outstanding fine to the court," you must contact the court, not the DMV. The letter will tell you where to send payment or documents and whether to send them to the MAU, the DMV, a court, or another agency.
Keep a copy of the letter and any proof that you complied (a receipt, a confirmation number, a certified mail receipt). If your license is suspended and you later need to show that you did comply, you will need that proof.
Common reasons for a Mandatory Actions Unit letter
The most frequent MAU action is license suspension for non-renewal. Your license expires on a specific date printed on the card. If you do not renew before that date, the DMV will send you a notice. If you do not renew within a set period after expiration, the MAU will send a letter saying your license will be suspended. You can renew online, by mail, or in person at a DMV office, depending on your age and when you last renewed.
Medical evaluation suspension is the second common reason. The DMV can require you to take a medical evaluation if you have a condition that may affect your ability to drive safely — a seizure disorder, vision loss, dementia, or a medication change, for example. If you do not show up for the evaluation or do not return the completed form, the MAU will suspend your license. You cannot ignore a medical evaluation request; you must either take the evaluation or request a hearing to contest it.
Suspension for unpaid fines or court orders happens when you owe money to a court for a traffic violation and the court has ordered the DMV to suspend your license. This is called a "failure to pay" suspension. The MAU letter will tell you the amount owed and which court to pay. You must pay the court, not the DMV. Once the court confirms payment, they notify the DMV and your suspension is lifted.
Other reasons include failing to report a change of address within 10 days of moving (required by law), not reporting a medical condition you are required to report, or not responding to a notice about a problem with your driving record.
What happens if you do not respond to the MAU letter
If you do not take the required action by the important date in the letter, your driver's license will be suspended. A suspension means you cannot legally drive in California. It also means you cannot legally drive in any other state — suspensions are reported to the National Driver Registry, and other states will honor California's suspension.
A suspended license can affect your job, your ability to get insurance, and your ability to register a vehicle. If you are caught driving on a suspended license, you can be cited, fined, and arrested. The fine for driving with a suspended license starts at $100 and can go much higher if you have prior violations.
You can still lift the suspension after it takes effect, but it is harder and more expensive. You will have to comply with the original requirement (renew your license, take the medical evaluation, pay the fine) and then pay a reinstatement fee to the DMV, usually $100 to $200. It is much simpler to comply before the important date.
How to respond to a Mandatory Actions Unit letter
First, understand exactly what action the letter requires. Read it twice if you need to. If the letter is unclear, call the MAU at the phone number listed on the letter and ask for clarification. The MAU staff can tell you what you need to do and where to send it.
Second, take the required action as soon as possible. Do not wait until the last day of the important date. If you need to renew your license, do it now. If you need to take a medical evaluation, call the evaluator listed in the letter and schedule an appointment. If you owe a fine, contact the court and pay it. Get proof of whatever you do — a confirmation email, a receipt, a tracking number.
Third, if you cannot meet the important date for a legitimate reason, contact the MAU before the important date and explain. You can ask for an extension. The MAU does not always grant extensions, but it is worth asking if you have a real hardship — you are hospitalized, you are out of the country, you did not receive the original notice. Do not wait until after the important date to ask.
If you believe the MAU action is wrong — for example, you already renewed your license but the letter says you did not — you can request a hearing. The letter will explain how to request a hearing. You have the right to present evidence and argue your case before a hearing officer. A hearing can delay the suspension while your case is reviewed, so it is worth requesting if you believe you are in compliance.
Scam alert: fake MAU letters and impersonation
Scammers send fake DMV and MAU letters to scare people into paying money or giving personal information. A real MAU letter will come from the California DMV and will have a DMV address and phone number on it. It will not ask you to pay by gift card, wire transfer, or cryptocurrency. It will not ask for your Social Security number or banking information over the phone or email.
If you receive a letter claiming to be from the MAU and you are not sure it is real, call the DMV directly at 1-800-777-0133 (not a number in the letter) and ask whether you have an active MAU case. Do not click links in emails claiming to be from the DMV. Do not call a phone number listed in a suspicious letter. Go to the official DMV website (dmv.ca.gov) and use the contact information there.
Real DMV letters come by mail, not email. If someone calls you claiming to be from the MAU and demands payment when ready, hang up and call the DMV directly. Legitimate government agencies do not threaten arrest or demand when ready payment by phone.
Frequently Asked Questions
Can I renew my license online if I have a Mandatory Actions Unit letter?
It depends on the reason for the letter. If the MAU letter is about non-renewal, you can renew online at dmv.ca.gov if you meet the online renewal requirements (your license is not more than five years expired, you are under 70, and you have no medical holds). If the letter is about a medical evaluation or another issue, online renewal will not resolve it — you must address the specific issue the letter names.
What if I did not receive the original DMV notice before the Mandatory Actions Unit letter?
Contact the MAU and explain that you did not receive the first notice. Provide your current address and ask them to resend the notice or extend the important date. The MAU may grant an extension if you can show you did not receive the original notice. Keep any evidence — a forwarding address change, a move confirmation — that shows why you missed it.
Can I drive while I wait for my medical evaluation appointment?
No. Once the DMV has sent you a medical evaluation notice, you should not drive. If you are caught driving after receiving a medical hold notice, you can be cited. Schedule the evaluation as soon as possible and comply with the important date in the MAU letter.
How long does it take for my license to be reinstated after I pay a court fine?
Once you pay the court, the court must notify the DMV. This can take one to three weeks. You can call the court to confirm they have processed your payment and ask them to send the clearance to the DMV. Your suspension will be lifted once the DMV receives the notification from the court.
What is the difference between a suspension and a revocation?
A suspension is temporary — your license is taken away for a set period or until you comply with a requirement, and you can get it back. A revocation is permanent or long-term — your license is cancelled and you must reapply and pass the written and driving tests again. The MAU letter will tell you which one applies to your case.
