Frequently Asked Questions
What offenses disqualify a CDL driver?
Per 49 CFR 383.51 — major offenses (1-year disqualification first offense, lifetime second): DUI/DWI, refusal to test, hit and run involving CMV, felony involving CMV, leaving the scene of an accident, using CMV in commission of a felony. Serious traffic violations (60-day suspension after 2nd in 3 years, 120-day after 3rd): excessive speeding 15+ over, reckless driving, improper lane change, following too closely. Railroad-grade-crossing violations have separate disqualification rules (60-365 days).
Are CDL disqualifications limited to on-duty driving?
No — major offenses (DUI, refusal, hit-and-run) disqualify the CDL whether the driver was operating a commercial or personal vehicle at the time. Per 49 CFR 383.51, off-duty DUI in a personal vehicle still triggers CDL disqualification. Many drivers don't realize this until after the off-duty incident.
How long is a CDL disqualification?
Major offense first conviction: 1 year (3 years if hauling hazmat). Major offense second conviction: lifetime ban (limited reinstatement after 10 years possible per 383.51(a)(7)). Felony with controlled substance: lifetime no reinstatement. Refusal to test: same as DUI tier. Two serious traffic violations in 3 years: 60-day suspension. Three in 3 years: 120-day. Railroad-grade-crossing: 60-365 days.
Who reports CDL disqualifications to FMCSA?
The state DMV that issues the CDL. State courts notify state DMV of convictions; state DMV updates CDL status and reports to FMCSA's Commercial Driver's License Information System (CDLIS). Carriers can query CDLIS through state DMV systems and the FMCSA Pre-Employment Screening Program (PSP). Most carriers query at hire and annually.
How does FileFlo track CDL status changes?
FileFlo's FMCSA rule-pack tracks CDL renewal cycles, endorsement status, MVR pull cadence (annual minimum, more frequent for endorsement holders), and disqualification flags from MVR queries. Per-driver CDL status linked to DQF — disqualification automatically removes the driver from safety-sensitive duty pool until status clears.
