Medical examiner certification requirements for CDL holders
Kansas CDL holders must meet the federal physical qualification standards in 49 CFR 391.41 and be examined by a medical examiner certified by FMCSA and listed on the National Registry of Certified Medical Examiners. The examiner documents the exam on MCSA-5875 and issues MCSA-5876, the Medical Examiner’s Certificate. A chiropractor, physician assistant, or nurse practitioner can perform the exam only if certified and listed on the Registry.
Core certification rules
A CDL medical certificate is generally valid for up to 24 months, but the examiner may set a shorter period for a condition that needs monitoring. Vision must be at least 20/40 in each eye with or without correction, with at least a 70-degree field of vision and the ability to recognize traffic signal colors. Hearing must meet the federal standard. Drivers with insulin-treated diabetes may be certified if the examiner completes the ITDM Assessment Form MCSA-5870 and the driver meets the stability requirements, including no severe hypoglycemia in the past 12 months. Drivers with a Skill Performance Evaluation certificate must carry it and follow its restrictions.
Self-certification and downgrade
Drivers must self-certify their operating category, usually non-excepted interstate for a Kansas CDL used in interstate commerce. The state records the medical certificate status. If the certificate expires or the driver fails to self-certify, the CDL is downgraded and the driver cannot operate a CMV requiring that CDL until the record is corrected.
Worked example: A driver with insulin-treated diabetes wants to keep an interstate CDL. The examiner must use MCSA-5870, confirm the driver has a stable insulin regimen and no severe hypoglycemic episodes in the past 12 months, and then may issue a certificate. If the driver had a recent severe episode, the examiner cannot certify at that exam.
Traps: using any doctor rather than a Registry-certified examiner; assuming every certificate lasts 24 months; ignoring a shorter monitoring period; and letting self-certification lapse so the CDL is downgraded.
