New Jersey DWI Statute — N.J.S.A. 39:4-50

Any person who operates a motor vehicle while under the influence of intoxicating liquor, narcotic, hallucinogenic or habit-producing drug, or operates a motor vehicle with a blood alcohol concentration of 0.08% or more by weight of alcohol in the defendant's blood, shall be guilty of a violation of this section. — N.J.S.A. 39:4-50(a). For a first offense with a BAC of 0.08% or higher but less than 0.10%, the statute provides a fine of not less than $250 nor more than $400 and a period of detainment of not less than 12 hours nor more than 48 hours, with ignition-interlock device installation in lieu of license suspension; higher BAC tiers and repeat offenses trigger stepped suspension and ignition-interlock periods under N.J.S.A. 39:4-50(a)(1)–(3) (as amended by P.L. 2019, c. 248).

What Commercial License (CDL) DWI Means in New Jersey

Commercial driver BAC threshold is 0.04% — half the standard 0.08% (N.J.S.A. 39:3-10.13). First-offense CDL DWI = 1-year CDL disqualification; second offense = lifetime CDL disqualification. CDL drivers face career-ending consequences from a single conviction.

The commercial license (cdl) dwi caseload in New Jersey is large enough that prosecutors and defenders alike develop pattern-recognition specific to the offense — the typical fact patterns, the recurring evidentiary issues, and the negotiated dispositions that resolve most cases short of trial. The Avery firm’s depth in DWI matters means we approach every commercial license (cdl) dwi file with that pattern-recognition built in.

The Statute Breakdown

The primary statute and supporting authorities controlling commercial license (cdl) dwi matters in New Jersey:

N.J.S.A. 39:3-10.13
49 C.F.R. 383.51
N.J.S.A. 39:4-50

The commercial license (cdl) dwi statute reads more narrowly than most defendants assume when they first see the charging document. The State must prove every element of the statute — and where the charging instrument fails to specify how the defendant’s conduct meets each element, that is itself a defense ground.

Penalties and Consequences

Commercial License (CDL) DWI convictions in New Jersey carry direct statutory penalties — fines, license consequences, jail / probation exposure, and points where applicable. But the larger consequence is often collateral:

Insurance impact — moving violations and most criminal convictions trigger insurance-rate increases for 3-5 years
Employment background checks — convictions surface on hiring background checks for at least 5-10 years (sometimes longer for certain offenses)
Professional licensing — many NJ professional boards (medical, nursing, real estate, financial-advisor) require disclosure of any conviction, including disorderly persons offenses
Immigration consequences — non-citizens face removal exposure for certain convictions; even a guilty plea to a minor offense can be a removable offense under federal immigration law
NJ MVC point exposure — Title 39 offenses feed the cumulative point total that triggers license suspension at 12 points

The full penalty exposure depends on the specific charge, the defendant’s prior record, and where the matter is filed. For a commercial license (cdl) dwi matter specifically, expect the statute’s stated penalty plus any of the collateral exposures above.

Common Defenses to Commercial License (CDL) DWI

Commercial License (CDL) DWI cases turn on the same core defense angles repeatedly. The Avery firm’s approach starts with the four pillars below; specific strategy varies by fact pattern, court, and defendant goals:

BAC-threshold challenge (0.04% lower margin for error)
Vehicle classification (commercial vs personal vehicle at time of offense)
Federal CFR vs state-law penalty interaction
Career-impact mitigation arguments at sentencing

The strongest defense in any commercial license (cdl) dwi matter is the one that fits the factual record. We don’t run formulaic defense — we read the discovery, look for the specific evidentiary, procedural, and constitutional gaps in the State’s case, and build defense theory from there. Where settlement is the right outcome, we negotiate hard from a position of trial-readiness; where trial is the right outcome, we go.

Avery & Avery’s Approach to Commercial License (CDL) DWI

Trial-firm DNA. Robert W. Avery served fifteen years as a New Jersey Municipal Court Judge before returning to defense practice. That bench experience shapes our reading of every commercial license (cdl) dwi file — what the prosecutor needs to prove, what the judge wants to see, where the case naturally settles.

Father-son continuity. John S. Avery joined the firm in 2012 and handles day-to-day appearances across our active caseload. The same firm handling intake, motion practice, and trial means clients aren’t bounced between unfamiliar attorneys at different stages.

Same-day callback. On active arrest or court-date situations, we return calls the same day during business hours. After-hours and weekend voicemails get returned the next business morning.

Statewide reach with a local foundation. Our home base is Ridgefield, Bergen County — but we appear in Bergen, Hudson, Essex, Passaic, Morris, and Sussex matters as a matter of routine. The commercial license (cdl) dwi caseload often crosses county lines (defendant residence, offense location, court of jurisdiction); our six-county practice handles that without difficulty.

Frequently asked questions

General educational answers. Every matter has facts that change the analysis — for advice on your situation, call the firm.

What is the legal blood-alcohol limit in New Jersey?

The per-se threshold for adult drivers is 0.08% BAC under N.J.S.A. 39:4-50(a). For commercial drivers it is 0.04% (N.J.S.A. 39:3-10.13). For drivers under 21 the limit is 0.01% under New Jersey's Zero Tolerance law. A driver may also be convicted of DWI based on observational evidence regardless of BAC.

What is the Alcotest 7110 and why does it matter?

The Alcotest 7110 MKIII-C is the breath-testing instrument approved for evidentiary use in New Jersey since State v. Chun, 194 N.J. 54 (2008). Chun set out two categories of foundational documents the State must produce — three "core" documents that go to substantive admissibility (most recent calibration report, new-standard-solution report, and 0.10 simulator-solution certificate of analysis) and twelve "non-core" foundational documents that must be produced in discovery (including the 20-minute observation log and operator credentials). Defense in many cases turns on these foundational requirements rather than the chemistry itself.

What happens if I refused the breath test?

Refusal is charged separately under N.J.S.A. 39:4-50.4a. A first-offense refusal carries license forfeiture comparable to a first-offense DWI plus IDRC and an ignition interlock. Conviction requires proof that the officer read the standard statement (the "second paragraph" issue under State v. Marquez), that the request was reasonable, and that the refusal was unequivocal.

Will I lose my license immediately?

New Jersey eliminated administrative pre-conviction license forfeiture in December 2019 (N.J.S.A. 39:4-50 as amended by P.L. 2019, c. 248). License loss now follows conviction. First-offense BAC under 0.10% triggers ignition interlock for 3 months in lieu of suspension; higher BAC and repeat offenses still trigger forfeiture periods. The exact exposure depends on the specific offense.

Are DWI charges expungeable in New Jersey?

No. DWI is a traffic offense under Title 39, not a criminal conviction under Title 2C, so it is not eligible for expungement under N.J.S.A. 2C:52-1 et seq. It does, however, count as a prior offense for sentencing purposes for ten years under the step-down rule (N.J.S.A. 39:4-50(a)(3)).
