Read guide →Common questions about these guides
Are these guides written by doctors?+
No. They're plain-English summaries of FMCSA rules and certified examiner guidance. For individual medical questions, talk to your doctor or an FMCSA-certified examiner.
How often are the guides updated?+
We review every guide whenever FMCSA publishes a rule change. The June 2025 NRII change is reflected in the renewal and 'what changed' guides.
Do the rules differ by state?+
DOT physical rules are federal — they're identical in every state. State DMVs only handle how the certificate is recorded against your CDL.
Can a guide tell me if I'll pass?+
Use the Will I Pass? checker for a personalized answer. The guides explain the rules; the checker applies them to your situation.
What if I have a question that isn't covered?+
Check the main FAQ page or call any clinic on the directory — most examiners will answer a quick eligibility question by phone for free.
