CDL drivers' self-certification requirements – What you need to know
Even though the exam procedures and standards are the same for commercial driver's license (CDL) and non-CDL drivers, determining a CDL driver's medical status is more complicated. Understanding the self-certification process helps avoids violations such, as no current medical certification on the motor vehicle record (MVR) when required.
A CDL holder must self-certify that their driving type is in one of four categories. If applicable, they must also submit to that licensing authority a copy of their medical examiner's certificate after every medical certification exam.
Interstate or intrastate commerce?
Before self-certifying, it's important to correctly determine whether interstate or intrastate applies is important.
Interstate commerce means that the driver crosses state lines or international borders. Interstate can also apply to one leg of a move where the driver does not leave the state but hauls freight or passengers coming from or heading to another state or country. Examples include moves from a warehouse, rail yard, or port, to a destination inside the same state.
Intrastate commerce occurs when interstate commerce is not involved.
When and how to self-certify
Drivers applying for a CDL for the first time must self-certify as part of the application process. Self-certification is also required when:
- Changing a driving tier/category (e.g.,moving from intrastate to interstate),
- Upgrading a CDL,
- Adding an endorsement,
- Transferring a CDL from another state, or
- Renewing a CDL.
Use the table below to determine the self-certification category or tier in four steps:
Step 1 – Determine if operating in interstate or intrastate commerce. See the explanation of interstate commerce above.
Step 2 - If interstate, select either tier 1 or 2. If not interstate, select intrastate tier 3 or 4.
Step 3 – Review the description and requirements for both tiers within Interstate (tier 1 or 2) or Intrastate (tier 3 or 4) and select which tier applies.
Step 4 – On the licensing authority's CDL driver self-certification web page or at an in-person visit, select the category or tier in which the driver expects to operate.
