Yes. 49 CFR 383.51 explicitly disqualifies a CDL for a first DUI conviction regardless of vehicle type. A CDL holder cited in a personal pickup truck at 0.08% still faces the one-year commercial disqualification. The federal framework treats the license as portable across vehicle categories. The chicagoduilawyer.net brand sees this catch clients off guard: they assume the personal-vehicle context protects the commercial credential. It does not. A CDL DUI defense must be structured to prevent conviction of the underlying DUI, because once conviction enters the record, the federal disqualification is automatic and the state cannot override it.
