- Classification: Class B Misdemeanor — same classification as personal DWI, but career consequences are permanent
- Jail exposure: 72-hour mandatory minimum — up to 180 days county jail (same as standard DWI)
- Maximum fine: $2,000 maximum
- License: 1-year CDL disqualification for first offense; lifetime disqualification for second offense
- ⚠️ CDL is disqualified even if charges are reduced or dismissed in some cases
The CDL Threshold Is Half the Standard Limit
Federal regulations set a separate BAC threshold for commercial vehicle operators: 0.04 — exactly half the 0.08 standard that applies to non-commercial drivers. A CDL holder blowing 0.05 in a personal vehicle on their day off is below the legal limit for a non-commercial driver — but above the federal threshold for their CDL status. The consequences apply to the license, not just the vehicle they were driving.
CDL Disqualification Is Separate From the Criminal Case
The criminal DWI charge and the CDL disqualification are two separate proceedings. A person can win the criminal case — or have it dismissed — and still lose their CDL through the administrative disqualification process. Federal regulations require states to disqualify a CDL holder for one year on a first DWI conviction. A second conviction triggers lifetime disqualification.
What This Means for Your Career
For a truck driver, bus driver, or anyone whose livelihood depends on a CDL, a DWI arrest is a career-threatening event. One year without the CDL means one year without the ability to drive commercially for any employer. Lifetime disqualification on a second conviction ends that career permanently.
- Disqualification applies during ALR suspension period + if convicted
- The CDL disqualification process is separate from your criminal proceeding — both must be addressed
- Commercial employers often terminate on arrest alone, before conviction, per their own policies
- An attorney who understands both the criminal defense and the federal CDL regulations is essential
