**Driver disqualification** means the person must not drive a CMV and the carrier must not permit CMV operation while the disqualification applies ([49 CFR 391.15(a)](https://www.ecfr.gov/current/title-49/section-391.15)). Triggers include loss of license, certain criminal convictions, out-of-service violations, and repeat texting or hand-held phone convictions.
