Guidance Q&A

Question 4: May the medical examiner restrict a driver’s duties?

Guidance: No. The only conditions a medical examiner may impose upon a driver otherwise qualified involve the use of corrective lenses or hearing aids, securement of a waiver or limitation of driving to exempt intracity zones (see §391.43(g)). A medical examiner who believes a driver has a condition not specified in §391.41 that would affect his ability to operate a CMV safely should refuse to sign the examiner’s certificate.
