For those who wish to drive a commercial motor vehicle (CMV)—such as truck drivers—a DWI/DUI conviction can have serious consequences. Not only does it impact your ability to obtain or retain a Commercial Driver’s License (CDL), but it can also jeopardize employment and future opportunities in the transportation industry. A New Hampshire DWI lawyer can help you navigate your situation effectively.
It’s worth noting that in New Hampshire, impaired driving laws use the term “DWI” (Driving While Intoxicated) rather than the commonly used “DUI” (Driving Under the Influence). Both terms refer to the criminal offense of operating a motor vehicle while impaired by alcohol, drugs, or other substances.

How a DUI/DWI affects your eligibility for a CDL in New Hampshire
Under both New Hampshire state law and federal regulations set by the Federal Motor Carrier Safety Administration (FMCSA), CDL drivers are held to a higher standard when it comes to impaired driving. The FMCSA mandates stricter rules for commercial motor vehicle operators because of the increased risks associated with large trucks and hazardous materials.
If you are convicted of DUI or DWI, you can face the following CDL-related consequences:
- For a first-time conviction OR Administrative License Suspension (ALS): Mandatory CDL suspension for at least one year, even if the DUI occurred in a personal (non-commercial) vehicle.
- If the DUI occurred while transporting hazardous materials, the suspension increases to three years.
- A second DUI conviction or Administrative License Suspension results in a lifetime disqualification from holding a CDL.
If you do not already have a CDL, you can apply for one after a DUI, but only after serving the full suspension period and meeting all reinstatement requirements. However, having a DUI on your record can make finding employment as a CDL holder extremely difficult, as most trucking companies perform thorough background checks.
What happens to your driving privileges after a DUI/DWI?
In New Hampshire, if you are arrested for driving under the influence (DUI) or DWI, your driving privileges will be immediately impacted. This includes both your regular driver’s license and your commercial driver’s license (CDL).
Consequences can include:
- Administrative license suspension through the Department of Motor Vehicles
- Possible jail time depending on the circumstances
- Fines, mandatory substance abuse programs, and probation
For CDL drivers, these penalties apply whether the offense occurred while driving a personal car or a commercial vehicle. This is because CDL holders are regulated by federal law, which enforces zero tolerance for serious traffic violations, including impaired driving.
Can you still work as a truck driver after a DUI?
Securing work as a CDL driver after a DUI conviction is challenging. Many trucking companies have strict hiring policies and may not consider applicants with recent DUI/DWI offenses. However, some factors may improve your chances over time:
- How long ago the DUI charge occurred
- Your overall driving history
- Completion of court-ordered programs and substance abuse treatment
Having experienced legal guidance from a defense attorney or law firm can help you mitigate the long-term impact of a DUI/DWI on your career.
