DOT Physicals Compliance Guide
Stay current on DOT physical examination requirements, medical certification standards, and FMCSA regulatory changes.
Overview
Department of Transportation physical examinations are a critical compliance requirement for employers in transportation, logistics, and any industry with commercial motor vehicle (CMV) operators. FMCSA regulations mandate that all CDL holders pass a DOT physical every two years (or more frequently for certain medical conditions). Recent years have seen expanded use of the National Registry of Certified Medical Examiners, updated guidance on sleep apnea screening, and evolving standards for diabetes and cardiovascular conditions.
Regulatory Landscape
DOT physicals are governed by FMCSA regulations under 49 CFR Part 391. All medical examiners must be listed on the National Registry, and exam results are reported electronically. Key areas of regulatory change include sleep apnea screening recommendations (which remain advisory but influence examiner practices), expanded guidance on insulin-treated diabetes exemptions, and updated vision and hearing standards. States cannot override federal DOT physical requirements, but they can set additional standards for intrastate-only carriers. Employers must ensure their medical examiner providers are National Registry-certified and staying current with FMCSA Medical Review Board recommendations.
Key Considerations
- 1Verify all medical examiners are listed on the FMCSA National Registry
- 2Track medical certificate expiration dates to prevent lapses in driver qualification
- 3Understand medical conditions that require more frequent recertification (annual or shorter)
- 4Implement proactive sleep apnea screening protocols to reduce examiner referrals
- 5Maintain driver qualification files with current medical certificates as required by Part 391
- 6Stay informed on FMCSA Medical Review Board advisories that may become mandatory

FMCSA Medical Examiner Certification Requirements
Certified Medical Examiners must maintain active registration in the National Registry and complete periodic training and testing for recertification. Examiners who fail to recertify are removed from the registry.
FMCSA Temporary Exemption for Paper Medical Examiner Certificates During NRII Transition
FMCSA issued a temporary exemption allowing interstate CDL and CLP holders and motor carriers to rely on paper copies of medical examiner certificates as proof of medical certification for up to 60 days after issuance while State Driver Licensing Agencies transition to the National Registry II (NRII) electronic system. The exemption runs April 11 through October 11, 2026. FMCSA does not anticipate granting additional nationwide NRII waivers after this period.
