CDL School Requirements Checklist: Medical Card, CLP, Background Check & Drug Test
Coach Ray audio brief for this topic
Loading audio...
TL;DR
Before you can start CDL training, you'll typically need: a valid driver's license, a DOT medical examiner's certificate (medical card) confirming you're fit to drive commercially, a Commercial Learner's Permit (CLP) which requires passing a written knowledge test, and a clean-enough driving/background record to satisfy your school and future employers. Some schools also run their own pre-enrollment screening on top of the state's requirements.

Warning:
If a school is not on the federal registry, you cannot get your license. All schools listed on CDL Schools USA are verified against the 2025 FMCSA database.
What Do I Need Before Starting CDL School?
A valid driver's license, a DOT medical card, a Commercial Learner's Permit (CLP), and an acceptable driving/background record are the core requirements before you start most CDL programs. Confirm exact specifics with your chosen school, since some details vary by state.
The Checklist
1. Valid Driver's License
A standard, non-commercial driver's license in good standing is the baseline starting point for CDL applicants.
2. DOT Medical Examiner's Certificate
A physical exam from a certified medical examiner confirming you meet FMCSA's physical qualification standards. Schedule this early since it can take time to book an appointment with an examiner listed on the National Registry.
3. Commercial Learner's Permit (CLP)
Requires passing a written knowledge test at your state DMV. Most students get this before starting behind-the-wheel training, though the exact order relative to ELDT theory training isn't federally mandated.
4. Driving and Background Record
Schools and, later, employers will review your driving record and often run a background check. Certain offenses can affect eligibility; see our guide on CDLs and criminal records for the specifics.
5. Proof of Identity and Residency
Standard documentation your state DMV requires for any commercial licensing application, typically a birth certificate or passport plus proof of address.

Beyond the state minimums, individual schools may run their own drug screening, additional background checks, or interview process before accepting a student. This is separate from your future employer's own hiring screening, so don't assume passing a school's intake process means you've automatically cleared every future employer's bar too.
Frequently Asked Questions
How long does the medical certification last?
Typically up to 2 years, though it can be shorter if your examiner identifies a condition requiring more frequent monitoring. You'll need to keep it current throughout your career, not just for initial licensing.
Can I start applying to schools before I have my CLP?
Usually yes, many schools will discuss enrollment and even start theory training before your CLP is finalized, but confirm this with your specific school since practices vary.
