California CDL Requirements
California law requires all CDL drivers to meet Federal Motor Carrier qualification requirements under 49 CFR part 391 and have a valid DOT medical card.
- Non-Excepted Interstate
You must meet the Federal DOT medical certificate requirements. - Non-Excepted Intrastate
You must meet the Federal DOT medical certificate requirements.
California does not have any State variances or exemptions from the federal physical standards. A commercial driver who does not pass the medical examination may qualify for a California intrastate restricted medical certificate (DL 51B). These drivers must submit a MER to DMV showing they did not pass the medical examination in order to be considered for an intrastate restricted medical certificate.
- Excepted
California does not issue a commercial driver license that is “Excepted” from driver qualification requirements.
Submit your Medical Certificate to California DMV
Drivers renewing their medical certificate may mail a copy of their forms MCSA-5875 and MCSA-5876.
Mail the completed MER and MEC to the address below at least four weeks prior to the expiration of your previous medical or your privilege to drive commercial motor vehicles could become invalid.
When submitting the MER, you are only required to submit pages 1-4. Page 5 of the MER addresses meeting medical standards with a State variance. A State variance would exempt a driver from the federal physical standards. California does not have any State variances or exemptions from the federal physical standards.

I drive a class d flatbed,stakeside good for aprox 35000 lb. normally within 125 miles and leave and return from the same location. My boss tells me that cense more than 50% of business is interstate they do not have to pay overtime. I see the boards every morning & not so true. In calif. can this be true
@Brian
This is not medical certification related question so we don’t have an answer for you.
You are a CA employee of a CA employer. You get paid per the CA overtime laws even if you work on the moon for 100% of the time. Report them to the state for payroll violations, so, everybody gets paid; and, they are forced to compete fairly with their competitors. You’re also likely entitled to back pay and likely penalties and interest.
I got my report passed on 09/22/2017. Doctor told me for submit in 7 days to dmv . But I don’t have time for submit my report within 7 days .can I submit after 7 days .tell me plz
Could I have my dad walk the paperwork in for me if I am out of state and can’t get to the DMV?
What is the California DOT requirement if I have to submit a cpap compliance report? Is it 30 day sleep report or 90 day?
@Lia
FMCSA regulations are 30 day compliance report.
Hello I just took my renewal physical the doctor walked into the room and ask me if I’d had a sleep apnea test. He didn’t do any part of the physical handed me a piece of paper told me to read it. He told my employer I needed a sleep apnea test does this jeopardize my job?
@Wade
No, just go to another examiner to get a second opinion / realistic based on medical health conditions.
Took my dot physical test back in January and passed. Didn’t mail or take the certification to the DMV as the medical office said it will be filed electronically. Is this true and how do I know if it was actually done?
@Matthew
The medical examiner’s office files the certification electronically to the Federal database.
It’s the driver’s responsibility to get it updated with their state DMV.
The doctor’s office may have sent it to DMV as a courtesy service, but the only way to know is to check with DMV that they have it.
What if your injured on the job and under workmancomp Doctor’s care. You can’t pass a DOT exam because your Doctor has not released you for work. Your medical card is up. What do you do then. Take your DOT exam when your released to full duty. Even after your medical card has expired for 6 months. What then ?
@Ronald
You need to contact your local drivers license department to find out the process to put things on hold until you can be medically certified again.
I’ve had my DOT card for 12 years. I have a question. I’ve been on a 10mg once a day blood pressure pill for over 12 years. When I when to dot doc yesterday a new doctor. My blood pressure was 131/83. This doctor marked that this medical certificate is only good for one year. When nothing has changed in my meds nor has my blood pressure ever been over 140 and it wasn’t over 140. In 12 years my medical report has always been good for the 2 years. His reason was for monitoring my hypertension. But my reg MD monitors my blood pressure. So is this right or has something changed.
@Corey
FMCSA wants all driver that are on blood pressure medications to be limited to one year at the time. That has been a rule for many years, you have just been dealing with examiners that didn’t know FMCSA regulations.
So I need to have an MER completed before I even set foot at the Dmv to apply for a Cdl permit ?
Thanks!
