CDL disqualification

In Michigan, MCL 257.625f provides that if a person who refused a chemical test was operating a commercial motor vehicle and does not request a hearing within the statutory period after notice, the secretary of state suspends all vehicle group designations on the person's operator's or chauffeur's license or permit, or nonresident privilege to operate a commercial motor vehicle. For a repeat refusal in a separate incident within a stated period of a prior refusal, Michigan's statute calls for revoking those designations for at least a stated period and until the person is approved for a vehicle group designation.

In Michigan, MCL 257.625f imposes the same commercial sanction on a person who was operating a commercial motor vehicle, requested a hearing and did not prevail, and allows a petition for review in the circuit court of the county of arrest. Michigan's statute imposes both the ordinary and commercial sanctions when the person was operating a commercial motor vehicle and was arrested for an offense listed in a separate section, with certain exceptions.

In Nebraska, Neb. Rev. Stat. § 60-498.02 requires a person operating a motor vehicle under an ignition interlock permit issued under that statute and its related sections to operate only a motor vehicle equipped with an ignition interlock device. Nebraska's statute also requires all such permits to indicate that the permit is not valid for the operation of any commercial motor vehicle.

In Pennsylvania, PennDOT's driver manual states that if a driving privilege is going to be suspended, revoked and/or disqualified, which the manual calls a sanction, a written notice will be mailed listing the date when the sanction will begin. In Pennsylvania, the manual says all such sanctions start on that effective date regardless of when a license or acknowledgment form is surrendered, and that all restoration requirements must be satisfied, in addition to serving the sanction, before the driving privilege is restored.

In Missouri, Mo. Rev. Stat. § 577.012 defines the offense of driving with excessive blood alcohol content to include operating a vehicle at or above a stated blood-alcohol level, or operating a commercial motor vehicle at or above a separate stated level. Missouri's statute provides that the level may be shown by chemical analysis of blood, breath, saliva or urine, with testing conducted under separate sections of Missouri law.

In Montana, Mont. Code Ann. § 61-8-1002 includes among the grounds for driving under the influence driving or being in actual physical control of a commercial motor vehicle within the state at or above a stated alcohol concentration, as shown by analysis of blood, breath, oral fluid or other bodily substance. Montana's statute sets that commercial ground apart from the stated concentration for a noncommercial vehicle on the ways of the state open to the public.

Deadlines, limits and penalty ranges are set by each state’s statutes, so this page does not state them. Each state page shows them with the official source and the date they were verified — or says plainly that a figure has not been confirmed yet.
