Summary

New Jersey runs sobriety checkpoints, and the Legislature has never passed a statute authorizing or regulating them. The phrase "sobriety checkpoint" returns no documents at all in the New Jersey General and Permanent Statutes. The single checkpoint statute on the books, N.J.S.A. 39:8-91, was enacted in 2015 to ban one specific practice: a roadside checkpoint or systematic vehicle inspection established for the sole purpose of inspecting motorcycles. It then says expressly that nothing in it restricts or limits "any other type of checkpoint, inspection, or roadblock conducted by a law enforcement agency for legitimate public safety reasons," which is as close as New Jersey statute law comes to endorsing the DWI checkpoint.

39:8-91 Prohibition of checkpoints limited to specific vehicle types.

1. A law enforcement agency shall not conduct a roadside checkpoint or other systematic inspection of vehicles along any public road, street, or highway of this State if the roadside checkpoint or systematic inspection is established for the sole purpose of inspecting motorcycles.

This section shall not be construed to restrict or limit in any capacity any other type of checkpoint, inspection, or roadblock conducted by a law enforcement agency for legitimate public safety reasons.

L.2015, c.27, s.1.

Full Breakdown

Read the section closely and it does two jobs. The prohibition in the first paragraph is narrow and specific: a law enforcement agency "shall not conduct a roadside checkpoint or other systematic inspection of vehicles along any public road, street, or highway of this State" where the checkpoint is set up for the sole purpose of inspecting motorcycles. The word doing the work is "sole." A checkpoint that stops every vehicle and happens to include motorcycles is untouched, and so is one aimed at impaired driving generally. The second paragraph is a savings clause that leaves every other checkpoint in place. New Jersey therefore governs checkpoint practice through case law and Attorney General policy rather than through the statute book, and there is no legislated requirement of advance publicity, no statutory command-approval rule and no statutory time limit on how long you may be held.

What you owe at the stop is statutory, and it is short. R.S. 39:3-29 requires you to have your driver's license, the vehicle's registration certificate and an insurance identification card in your possession while in charge of the vehicle, to exhibit all three on request by a police officer, and to write your name in the officer's presence. Registration and insurance may be shown on a phone, tablet or computer, and the same section provides that doing so "does not constitute consent for a police officer or judge to access any other contents on the device." Failing to produce is a $150 fine, and the municipal court judge may dismiss the charge if you later exhibit documents that were valid on the day you were charged.

Smell alone cannot escalate a New Jersey checkpoint stop. N.J.S.A. 2C:35-10c, enacted as section 61 of the 2021 legalization act, provides that the odor of cannabis or burnt cannabis, possession of no more than the lawful amount, and that possession in proximity to any amount of cash are none of them reasonable articulable suspicion of a crime, individually or collectively, except on school property owned by a school or school board and inside detention, adult correctional and youth correction facilities. A roadside checkpoint is none of those places.

Breath testing at a New Jersey checkpoint is governed by implied consent, but the consent is conditional. N.J.S.A. 39:4-50.2(a) deems every operator on a public road, street, highway or quasi-public area in the State to have consented to breath samples, but only where the request comes from "a police officer who has reasonable grounds to believe that such person has been operating a motor vehicle in violation of" R.S.39:4-50. Subsection (e) then bars any forcible test: no chemical test or specimen "may be made or taken forcibly and against physical resistance thereto by the defendant." The officer must instead read a standard statement prepared by the Chief Administrator of the Motor Vehicle Commission telling you what refusal costs.

Refusal is its own offense in New Jersey, charged under N.J.S.A. 39:4-50.4a and heard in the municipal court. A first refusal costs a fine of not less than $300 and not more than $500, plus forfeiture of driving privileges until an ignition interlock device is installed in the vehicle you most often operate. A second refusal adds a one to two year forfeiture running after installation and a fine of $500 to $1,000, and a third or subsequent refusal carries an eight year forfeiture and a $1,000 fine. Before convicting, the municipal court must find by a preponderance of the evidence that the arresting officer had probable cause to believe you were driving or in actual physical control while under the influence, that you were placed under arrest where appropriate, and that you refused on request. If those elements are not established, no conviction issues.

The underlying offense is R.S. 39:4-50, which sets the blood alcohol threshold at 0.08 percent. A first offense at 0.08 percent or higher but less than 0.10 percent draws a fine of $250 to $400, 12 to 48 hours at an Intoxicated Driver Resource Center spread over two consecutive days of at least six hours each, up to 30 days imprisonment in the court's discretion, and forfeiture of driving privileges until an ignition interlock is installed. New Jersey also lets a driver arrested in that band install the interlock voluntarily before conviction and ask the Motor Vehicle Commission for a license carrying the interlock notation, and a driver who does so and who held a valid New Jersey license in good standing at the time of the offense is not subject to the fine.

Violations & Penalties

A. 4a in the municipal court, with a $300 to $500 fine and license forfeiture until an ignition interlock is installed on a first offense, $500 to $1,000 and a one to two year forfeiture on a second, and $1,000 with an eight year forfeiture on a third or subsequent. 39:4-50(f), and a conviction for a substantially similar offense in another jurisdiction counts as a prior. 39:4-50 conviction arising from the same incident. S. 39:3-29. A. 39:8-91, which carries no penalty clause of its own and operates as a prohibition on the agency rather than an offense chargeable against a driver.

Frequently Asked Questions

Are DWI checkpoints legal in New Jersey?
They operate across the State, and no statute forbids them. New Jersey never enacted a sobriety checkpoint statute, so the practice rests on court decisions and Attorney General policy. The Legislature did address checkpoints once, in N.J.S.A. 39:8-91, and that section says nothing in it restricts "any other type of checkpoint, inspection, or roadblock conducted by a law enforcement agency for legitimate public safety reasons."
Is there a New Jersey checkpoint that is actually illegal?
Yes, one kind. Since L.2015, c.27 a law enforcement agency may not conduct a roadside checkpoint or other systematic inspection of vehicles on any public road, street or highway in New Jersey if it is established for the sole purpose of inspecting motorcycles. A general checkpoint that stops motorcycles along with everything else is not covered.
What do I have to hand over at a New Jersey checkpoint?
Your driver's license, the registration certificate and an insurance identification card, under R.S. 39:3-29, and you must also write your name in the officer's presence. Registration and insurance may be displayed on a phone or tablet, and doing that is not consent for the officer to look at anything else on the device. Failing to produce is a $150 fine, though the municipal court judge may dismiss the charge if you bring documents that were valid on the day of the summons.
Can I refuse the breath test at a New Jersey checkpoint?
You can physically refuse, and N.J.S.A. 39:4-50.2(e) says no test may be taken forcibly against your physical resistance, but refusal is a separate offense under N.J.S.A. 39:4-50.4a. A first refusal brings a $300 to $500 fine and loss of driving privileges until an ignition interlock device is installed in the vehicle you most often operate. The municipal court must still find that the officer had probable cause to believe you were driving under the influence before it can convict.
Can the smell of marijuana at a checkpoint turn into a search of my car?
Not by itself in New Jersey. N.J.S.A. 2C:35-10c removes cannabis odor, lawful-quantity possession, and lawful-quantity possession near cash from the reasonable articulable suspicion analysis, and says they do not count individually or collectively. The section's exceptions cover school property, detention facilities, adult correctional facilities and youth correction facilities, none of which describes a public road.
What does a first New Jersey DWI conviction cost?
R.S. 39:4-50 sets the threshold at a blood alcohol concentration of 0.08 percent. For a first offense at 0.08 percent or higher but under 0.10 percent, the fine is $250 to $400, with 12 to 48 hours at an Intoxicated Driver Resource Center over two consecutive days of at least six hours each, up to 30 days imprisonment at the court's discretion, and forfeiture of driving privileges until an ignition interlock is installed.
