For a commercial driver in Maryland, a DUI is defined under Md. Code, Transportation Art. § 21-902. The legal limit for blood alcohol concentration (BAC) is lower for CDL holders—0.04% while operating a commercial vehicle, compared to 0.08% for non-commercial drivers. A BAC at or above 0.04% can lead to an immediate out-of-service order and form the basis for a DUI charge. The stakes extend beyond standard penalties, directly impacting your federally-regulated commercial driving privileges under Maryland and Federal Motor Carrier Safety Administration (FMCSA) rules.

FAQs for Truck Drivers Facing DUI in Rockville
What happens to my CDL after a DUI arrest in Rockville?
Your CDL is immediately at risk. You face two actions: a criminal case in District Court and an MVA administrative case. You must request an MVA hearing within 10 days of arrest to contest the automatic suspension. A conviction for DUI (BAC ≥0.04 in a commercial vehicle) mandates a 1-year CDL disqualification.
Is the legal limit lower for truck drivers in Maryland?
Yes. The BAC limit is 0.04% when operating a commercial motor vehicle (CMV), per FMCSA regulations adopted in Maryland. A BAC at or above 0.04% can support a DUI charge and trigger an immediate out-of-service order, even if you are below the 0.08% limit for personal vehicles.
Can I get a PBJ (Probation Before Judgment) for a DUI and keep my CDL?
It depends. While a PBJ avoids a criminal conviction, the MVA still assesses 12 points against your driving record. For CDL holders, accumulating points or receiving a PBJ for a major offense like DUI may still lead to disqualification by your employer or the FMCSA. An attorney can negotiate for a charge reduction to a non-disqualifying offense.
What is the 10-day rule for a Maryland DUI?
After a DUI arrest, you have only 10 calendar days to request an administrative hearing with the Maryland Motor Vehicle Administration (MVA) to challenge the driver’s license suspension. Missing this deadline waives your right to contest the suspension, which will become final. This process is separate from your criminal court case.
Should I refuse a breath test if I’m a commercial driver?
No. Refusal triggers an automatic 270-day license suspension for a first offense and a separate 1-year disqualification of your CDL. It also makes you ineligible for a restricted license with an ignition interlock. Refusal can be used as evidence of guilt in your criminal trial.
