Maryland DUI Law for Commercial Drivers
A DUI charge carries heightened stakes for commercial drivers. Maryland law imposes stricter standards and harsher penalties on holders of a Commercial Driver’s License (CDL). While the general per se limit is 0.08% BAC, a CDL holder is considered under the influence at 0.04% when operating a commercial vehicle. A conviction triggers mandatory disqualification periods from driving a commercial motor vehicle (CMV).
For a first DUI offense, federal regulations mandate a one-year disqualification of your CDL. A second offense results in a lifetime disqualification, though reinstatement may be possible after ten years under certain conditions. These penalties apply even if the DUI occurred while you were driving your personal vehicle. The administrative and criminal processes run concurrently, requiring a defense strategy that addresses both fronts to protect your career.
- Secure your CDL documentation and the traffic citation immediately.
- Contact a DUI defense attorney Baltimore before your scheduled court date or MVA hearing.
- Your attorney will request discovery from the prosecutor to review evidence like breathalyzer calibration logs.
- Prepare for and attend all court hearings at the District Court in Towson to address the criminal charge.

Baltimore County Truck Driver DUI FAQs
Is the legal limit lower for truck drivers in Maryland?
Yes. The BAC limit is 0.04% for CDL holders operating a commercial vehicle, half the standard 0.08% limit.
Can I lose my CDL for a DUI in my personal car?
Yes. Federal regulations mandate a one-year disqualification of your commercial driving privileges for any DUI conviction, regardless of whether you were in a commercial or personal vehicle at the time of the offense.
What is the best defense for a truck driver DUI?
It depends on the facts. Common defenses challenge the legality of the traffic stop, the administration and calibration of breath or blood tests, and whether you were in actual physical control of the vehicle. An experienced truck driver DUI lawyer Baltimore can identify the strongest strategy.
How quickly should I contact a lawyer after a DUI arrest?
Immediately. You have only 10 days in Maryland to request a hearing with the Motor Vehicle Administration (MVA) to contest your driver’s license suspension. A drunk driving defense lawyer Baltimore can handle this request and begin building your criminal defense.
Can I get a Probation Before Judgment (PBJ) for a CDL DUI?
While a PBJ may be available under Maryland law for a first-time DUI offender and avoids a conviction on your state record, it may not prevent the federal one-year CDL disqualification. A DUI defense attorney Baltimore can advise on the specific interactions between state and federal law.
