DUI Defense for Commercial Drivers: Protecting Your Livelihood

Schwartz, Hanna, Olsen, & Taus June 9, 2025

Glass of Alcohol, Handcuffs and Car KeysDriving under the influence (DUI) charges are serious for anyone, but for commercial drivers, the stakes are even higher. A single DUI conviction can cost a commercial driver their job, their commercial driver’s license (CDL), and their ability to support themselves and their families. Unlike non-commercial drivers, CDL holders are held to stricter legal standards.

In New Jersey, CDL holders face harsher penalties, lower blood alcohol concentration (BAC) thresholds, and lasting consequences. This is why turning to Schwartz, Hanna, Olsen, & Taus in Metuchen, New Jersey, is so important when facing DUI charges. As an experienced DUI attorney, I’ve the experience to craft the right legal strategy to protect your CDL and your future.

An Overview of the Unique Challenges CDL Holders Face

Commercial drivers are held to a higher standard than the average motorist. Not only are their BAC limits lower, but they're also subject to stricter rules regarding testing, reporting, and penalties. A DUI arrest doesn't just impact their driving record—it can lead to license suspension, job termination, and loss of professional reputation.

Before getting into potential defenses, it’s important to understand what makes DUI charges more difficult for CDL holders than other drivers. Key challenges for commercial drivers include:

  • Lower BAC threshold: While most drivers face DUI charges at 0.08% BAC or higher, CDL holders can be charged at just 0.04% while operating a commercial vehicle, according to the Federal Motor Carrier Safety Administration

  • Severe CDL penalties: A first-time DUI can result in a one-year suspension of a CDL, even if the incident occurred while driving a personal vehicle.

  • Employment consequences: Many trucking companies have zero-tolerance policies for DUI arrests, not just convictions.

  • Insurance issues: A DUI can make it difficult or impossible to secure commercial auto insurance, which is often required for employment.

  • Federal and state overlap: CDL holders are regulated by both federal guidelines and New Jersey law, making the DUI charges more difficult to deal with.

Any one of these factors can impact your future, which is why it’s so important to turn to legal professionals when you face DUI charges.

The Legal Process After a DUI Arrest

After a DUI arrest, the legal process begins immediately and involves both criminal and administrative steps. CDL holders often face a faster timeline and additional reporting obligations than non-commercial drivers. Here are some steps you can expect to take after a DUI arrest:

  • Initial arrest and license confiscation: Law enforcement may confiscate your license on the spot and issue a temporary permit.

  • Notice of suspension: The New Jersey Motor Vehicle Commission (MVC) will notify you of a pending suspension.

  • Criminal charges: You'll receive a court date for the DUI charge itself, which will be heard in municipal court.

  • MVC hearing: Separate from your court appearance, the MVC may hold a hearing to determine the fate of your CDL.

  • Employer notification: Many commercial drivers are required to notify their employers of DUI charges immediately, even before conviction.

Each of these steps can impact your ability to keep your CDL and continue working. This is why quick action is so important.

Common DUI Defenses for CDL Holders

The right DUI defense strategy depends on the facts of your case. Not every DUI charge leads to a conviction. There may be opportunities to challenge the traffic stop, field sobriety tests, chemical testing, or other aspects of the case. Some effective DUI defense strategies include:

  • Challenging the traffic stop: Police must have a valid reason to pull you over. If they didn’t, any evidence gathered afterward may be suppressed.

  • Questioning the BAC results: Breathalyzers and blood tests aren’t always accurate. Calibration errors, mishandling, or improper administration can cast doubt on the results.

  • Examining field sobriety tests: These tests are subjective and often influenced by fatigue, health issues, or environmental conditions.

  • Raising procedural violations: If law enforcement violated your rights during the arrest or investigation, that can affect the strength of the case against you.

  • Investigating the chain of custody: Blood samples must be properly stored and documented. Gaps in the chain of custody can undermine the results.

  • Reviewing video and audio evidence: Dashcam or bodycam footage may contradict the officer's account or show improper procedures.

These defenses can potentially reduce the charges, result in a dismissal, or help secure a favorable plea agreement.

CDL-Specific Penalties and Consequences

Even if a CDL holder avoids jail time, the professional fallout from a DUI can be devastating. New Jersey law includes CDL-specific penalties that go beyond those faced by typical drivers. Some penalties CDL holders may face include:

  • One-year CDL disqualification: This applies even for first offenses, and it doubles to a lifetime disqualification for hazardous materials drivers.

  • Lifetime CDL revocation for second offenses: A second DUI conviction will almost always result in permanent loss of your commercial driving privileges.

  • Employment loss: Most employers won’t retain a driver charged with or convicted of DUI, regardless of the outcome in court.

  • Restricted employment opportunities: Even after serving your suspension, finding a new employer willing to hire a driver with a DUI record can be very difficult.

  • Increased insurance costs: High-risk insurance premiums may make returning to work financially unfeasible.

Because these penalties are so severe, defending your case aggressively is critical for protecting your livelihood.

Special Concerns for Out-of-State CDL Holders

If you're a commercial driver licensed in another state but charged with DUI in New Jersey, your situation is even more delicate. Although the charge occurred in New Jersey, your home state will likely be notified, and the consequences can follow you across state lines. Some concerns for out-of-state drivers include:

  • License suspension in multiple states: Your CDL may be suspended in both New Jersey and your home state.

  • Federal reporting requirements: DUI convictions are reported to the Federal Motor Carrier Safety Administration (FMCSA), affecting your status nationwide.

  • Logistical issues: Attending court hearings in New Jersey while living in another state can be a major burden.

  • Legal representation across jurisdictions: You’ll need a New Jersey-based DUI attorney to represent you in local court and protect your driving record.

Out-of-state drivers should act quickly to coordinate a defense, especially since delays can trigger automatic suspensions.

What to Do After a DUI Arrest as a CDL Holder

Time matters after a DUI arrest. Taking immediate steps to protect yourself can make a significant difference in your ability to keep driving and avoid harsher penalties. Here are some steps you should take after a DUI arrest.

  • Contact a DUI attorney immediately: The sooner you speak to a lawyer, the sooner you can begin building your defense.

  • Avoid talking to police without legal counsel: You have the right to remain silent. Use it.

  • Request a copy of the police report: This document will provide important details your attorney can use in your defense.

  • Write down everything you remember: The details of the traffic stop, arrest, and testing procedures can be valuable evidence.

  • Follow court and MVC deadlines: Missing a court date or hearing can automatically worsen your situation.

Taking these steps early shows that you're serious about defending your record and preserving your future.

Avoiding Future DUI Charges

While fighting your current charges is critical, it's also smart to think about prevention moving forward. Even a single DUI can lead to lifetime CDL revocation in some cases. Here are some simple ways to avoid future DUI charges:

  • Don’t drink and drive, even off-duty: CDL penalties can apply even when you're behind the wheel of a personal vehicle.

  • Be cautious with prescription medications: Some legally prescribed medications can impair driving or trigger a DUI charge.

  • Understand zero-tolerance policies: Many companies have stricter rules than state law, including termination after any alcohol-related arrest.

  • Maintain good records: Keep documentation of any alcohol education or rehabilitation programs you've attended.

Protecting your future means not only beating your current charges but avoiding the situation altogether going forward.
