CDL DWI in New Jersey
Laws, Penalties & License Impact
Introduction to CDL DWI in New Jersey (Commercial Driver DWI Guide)
A DWI conviction can end a commercial driving career in New Jersey. This guide explains exactly what CDL holders need to know — from BAC limits and penalties to license suspensions, federal regulations, defenses, and restoration options.
It also highlights new updates in the law, including the 2024 FMCSA Clearinghouse rules and changes to ignition interlock requirements. Whether your charge stems from driving a commercial truck or a personal car, this page outlines the risks to your CDL and the strategies that may help protect your future.
FMCSA Regulation 383.51 and the CDL. .04 BAC Rule
The Federal Motor Carrier Safety Administration (FMCSA) sets national standards. Under Regulation 383.51:
- CDL holders can be charged at .04% BAC in a CMV
- First offense = 1-year CDL loss (3 years if HazMat)
Second offense = lifetime disqualification (with a rare 10-year reinstatement option)
24-Hour Out-of-Service Rule for CDL Drivers
Under federal law, if any alcohol is detected while you are operating a commercial motor vehicle, you face an automatic 24-hour out-of-service order. This applies even if your BAC is below .04%. It’s one of the strictest rules CDL drivers must follow, which can have immediate consequences for your job.

Commercial Vehicle vs. Personal Vehicle DWI: CDL Impacts in NJ
Even if a DWI occurs in your personal vehicle, your CDL will be disqualified for at least one year. Out-of-state DWI convictions are also reported to New Jersey under CDLIS and count against you.
Refusal to Submit To Testing as a CDL Driver
- CMV Refusal: CDL disqualification of 1 year for first offense, 3 years if HazMat, lifetime for a second offense.
- Personal Vehicle Refusal: A CDL disqualification of 1 year applies for a first refusal, with longer penalties for repeat violations.

CDL Penalties and Employment Consequences in New Jersey
A CDL DWI conviction threatens your livelihood.
First Offense
- CDL Disqualification: 1 year (3 years if HazMat)
- Regular License Suspension: 3–12 months
- Fines: $250–$500
- Jail: Up to 30 days
- Ignition Interlock: 3–12 months
- Career Impact: CDL job loss is highly likely
Second Offense
- CDL Disqualification: Lifetime ban (with limited 10-year reinstatement possibility)
- Regular License Suspension: 2 years

- Jail: 2–90 days
- Ignition Interlock: 1–3 years

Employment & Insurance Impacts
- Employer Termination: Most carriers have zero-tolerance policies regarding DWI.
- Insurance Premiums: Even a first offense can make you uninsurable.
- CSA Scores: Violations affect a company’s Compliance, Safety, Accountability (CSA) score, making drivers with DWIs less attractive to employers.
Clearinghouse Reporting: Employers must check your CDL status before hiring or continuing employment.
Out-of-State CDL DWI Convictions & the Interstate Driver’s License Compact
New Jersey is part of the Interstate Driver’s License Compact, meaning out-of-state DWI convictions count against your NJ CDL. You cannot escape CDL penalties by being charged elsewhere.
Minor Violations and Serious CDL Consequences
Beyond DWI, CDL holders can face suspension for other violations, including:
- Driving 15+ mph over the speed limit
- Reckless driving convictions
- Leaving the scene of an accident (CMV or personal vehicle)
- Operating a CMV while the license is suspended
- Overweight violations that trigger CDL penalties
- Refusing chemical testing
Even “minor” violations can build toward disqualification under federal rules.
The 10-Year Step-Down Rule and CDL Restoration in New Jersey
A second CDL DWI usually leads to lifetime revocation. However, New Jersey law allows for a possible 10-year reinstatement if you complete a rehabilitation program and meet strict reinstatement conditions. This is rare, but it may apply in select cases.
Review our guide on New Jersey’s 10-Year Step-Down Rule for DWI.
FMCSA Clearinghouse II & CDL Employer Reporting (2024 Update)
Since November 18, 2024, states must downgrade CDL/CLPs when a driver is listed as “prohibited” in the FMCSA Clearinghouse. A driver remains prohibited until completing the Return-to-Duty process, which includes substance abuse evaluation and testing.
IDRC/IDP and Post-Conviction Requirements for CDL Drivers
Convicted drivers must attend the Intoxicated Driver Resource Center (IDRC), which includes 12–48 hours of education, evaluation, and treatment referrals. Completion is required before a CDL or license can be restored.

New Jersey CDL DWI FAQ
Understanding CDL DWI Basics
What is the legal BAC limit for CDL drivers in New Jersey?
The legal limit is 0.04% for CDL drivers, compared to 0.08% for standard motorists.
How is a CDL DWI different from a regular DWI in New Jersey?
A CDL DWI can occur in both commercial and personal vehicles and carries stricter penalties.
Does New Jersey follow federal CDL disqualification rules?
Yes. New Jersey enforces federal CDL rules, including the one-year suspension and lifetime ban framework.
Penalties & License Consequences
What happens to my CDL if I’m convicted of a DWI?
You could lose your CDL for one year for a first offense. A second conviction typically results in a lifetime disqualification.
Is a CDL suspension the same as a regular license suspension?
No. A suspended CDL prevents you from driving commercial vehicles, but you may still drive a personal vehicle if your basic license is valid.
Will a first-time DWI lead to a lifetime CDL disqualification?
Only for HazMat drivers. For others, the first offense results in a one-year disqualification.
Do out-of-state DWI convictions affect my NJ CDL?
Yes. DWI convictions in any state are reported to New Jersey and can disqualify your CDL.
Court Process & Enforcement
Will I lose my CDL immediately after a DWI arrest?
If you refuse or fail chemical testing, you may face an administrative suspension shortly after your arrest.
How long does the DWI court process take?
Cases vary, but most CDL-related DWI court processes take several months.
Can I get a work license or hardship CDL in New Jersey?
No. New Jersey law does not allow for hardship or conditional CDLs.
Defenses & Legal Strategy
Can I challenge the results of a breathalyzer test in a CDL DWI case?
Yes. Breathalyzer challenges are a common defense, especially if the device was mis-calibrated or mishandled.
What defenses are available to CDL drivers charged with DWI?
Possible defenses include medical conditions, testing errors, constitutional violations, and lack of probable cause.
Can my lawyer negotiate my CDL DWI down to reckless driving charges?
Sometimes. Negotiations are possible, but a reduction is never guaranteed.
What if the police made mistakes during my traffic stop?
If the stop was unlawful or procedures weren’t followed, your lawyer may challenge the evidence and seek dismissal.
Restoration & Career Impact
How do I restore my CDL after a DWI suspension?
To restore your CDL after suspension, you must complete IDRC, pay reinstatement fees, and sometimes retake CDL testing.
Can I ever get my CDL back after a lifetime disqualification?
Usually no. Lifetime bans are permanent, but a 10-year reinstatement option may apply in rare cases.
How will a DWI affect my employment as a commercial driver?
Most carriers terminate drivers after a DWI. A second conviction usually ends your CDL career permanently.
