A single DWI can mean thousands of dollars in fines and surcharges, an ignition interlock device on your car, a stay at an Intoxicated Driver Resource Center, and possible jail time. Prior convictions make every one of those penalties steeper.This guide sets out the current NJ DWI penalties under N.J.S.A. 39:4-50 and the breath-test refusal statute, N.J.S.A. 39:4-50.4a. It reflects the ignition interlock reforms that took effect in December 2019, which the Legislature extended through January 1, 2029. If you were charged in Freehold, Middletown, Howell, Asbury Park or any other Monmouth County town, call Keith Oliver Criminal Law at (732) 858-6959 to discuss your case.NJ DWI Penalties at a GlanceNew Jersey sets DWI penalties by two things: how many prior DWI convictions you have, and, for a first offense, your blood alcohol concentration (BAC). The table below summarizes the range a municipal court judge can impose.OffenseFineJailLicense forfeitureIgnition interlock1st offense, BAC .08%\u2013.099%$250\u2013$400Up to 30 daysUntil interlock is installed3 months1st offense, BAC .10%\u2013.149%$300\u2013$500Up to 30 daysUntil interlock is installed7 months\u20131 year1st offense, BAC .15% or higher$300\u2013$500Up to 30 days4\u20136 monthsDuring forfeiture + 9\u201315 months1st offense, drug DWI$300\u2013$500Up to 30 days7 months\u20131 yearNot applicable2nd offense$500\u2013$1,00048 hours\u201390 days + 30 days community service1\u20132 yearsDuring forfeiture + 2\u20134 years3rd or later offense$1,000180 days8 yearsDuring forfeiture + 2\u20134 yearsOn top of the court penalties, the New Jersey Motor Vehicle Commission (MVC) adds an insurance surcharge of $1,000 per year for three years. Court costs and statutory fees also apply, including a $100 Drunk Driving Enforcement Fund fee and a $100 Alcohol Education, Rehabilitation and Enforcement Fund fee.First Offense DWI Penalties by BACFor a first offense, the most important number is your BAC reading on the Alcotest. New Jersey divides first offenders into three tiers.BAC of .08% to under .10%This is the lowest tier. The fine is $250 to $400, and the judge may impose up to 30 days in jail, although jail is rare for a first offense. You must complete 12 to 48 hours at the Intoxicated Driver Resource Center (IDRC). Instead of a traditional suspension, your license is forfeited only until you install an ignition interlock device, which stays on your car for three months.BAC of .10% to under .15%The fine rises to $300 to $500, with the same possible 30 days in jail and IDRC requirement. Your license is forfeited until an interlock is installed, and the device stays on for seven months to one year.BAC of .15% or higherAt this level the penalties jump. You face a $300 to $500 fine and the same IDRC requirement, plus a license forfeiture of four to six months. The interlock must be installed during the forfeiture and kept on for another nine to fifteen months after your license is restored.Drug DWIA DWI based on drugs, including marijuana, carries a fine of $300 to $500 and a license forfeiture of seven months to one year. An interlock does not detect drugs, so drivers charged with drug DWI are not eligible for the interlock credit that can shorten a suspension.License forfeiture and ignition interlock periods by offense (maximum of each statutory range).Second Offense DWI PenaltiesA second DWI conviction brings mandatory jail time. The judge must impose at least 48 consecutive hours in jail and can impose up to 90 days. You also face:A fine of $500 to $1,00030 days of community serviceA license forfeiture of one to two yearsAn ignition interlock during the forfeiture and for two to four years after your license is restoredIDRC detainment of 48 hours and any treatment the IDRC recommendsAn MVC surcharge of $1,000 per year for three yearsThird Offense DWI PenaltiesA third or subsequent DWI is the most serious level. The law requires 180 days in the county jail. The judge may reduce up to 90 of those days for time spent in an approved inpatient rehabilitation program. The fine is $1,000, the license forfeiture is eight years, and an interlock is required during the forfeiture and for two to four years afterward. If the third offense comes within three years of the prior one, the MVC surcharge rises to $1,500 per year for three years.Possible jail time by offense under N.J.S.A. 39:4-50.The 10-Year Step-Down RuleNew Jersey gives some relief to drivers whose prior DWI is old. If your second offense happens more than 10 years after your first, the court sentences you as a first offender. If your third offense happens more than 10 years after your second, you are sentenced as a second offender. The older conviction still stays on your driving record, so it is important to review your full abstract before your first court date.Breath Test Refusal PenaltiesRefusing to provide breath samples is a separate violation under N.J.S.A. 39:4-50.4a. You can be convicted of refusal even if the State cannot prove you were intoxicated, and a refusal conviction can run alongside a DWI conviction.RefusalFineLicense forfeitureIgnition interlock1st refusal$300\u2013$500Until interlock is installed9\u201315 months after restoration2nd refusal$500\u2013$1,0001\u20132 yearsDuring forfeiture + 2\u20134 years3rd or later refusal$1,0008 yearsDuring forfeiture + 2\u20134 yearsRefusal also carries the same $1,000-per-year MVC surcharge for three years and requires completion of the IDRC program.Fines and MVC surcharges alone, before court costs, IDRC fees, interlock costs and higher insurance premiums.How the Ignition Interlock Credit WorksRecent amendments let many drivers install an ignition interlock device after arrest, before the case is resolved. Drivers who do so can earn a credit of one day against the license forfeiture for every two days the device is installed. For a driver facing a long forfeiture, early installation can mean getting back on the road much sooner.The credit is not available if the DWI caused serious bodily injury to another person, if the charge is a drug-based DWI, or if the driver was operating a commercial vehicle under the influence of a controlled substance. Whether early installation makes sense depends on the strength of the State’s case, so speak with a lawyer before you install a device.Penalties That Can Make a DWI WorseCertain facts expose you to additional charges that run on top of the standard DWI penalties:DWI with a child under 17 in the car, which is a separate disorderly persons offense with its own license suspensionAssault by auto or other criminal charges if someone was injured in a crashDriving while suspended for a DWI, which can carry mandatory jailA commercial driver’s license (CDL) disqualification, which applies even when you were driving your personal carHidden Costs of a DWI ConvictionThe fine is often the smallest part of the bill. When you add the three-year surcharge, IDRC fees, the cost of leasing and monitoring an interlock device, and higher car insurance premiums, a first-offense DWI can cost $10,000 or more over three years. A DWI also stays on your driving record permanently and cannot be expunged, because it is a traffic offense rather than a criminal conviction. It can affect employment that involves driving, professional licenses and travel to Canada.A DWI conviction stays on your New Jersey driving record permanently.Can a DWI Charge Be Fought in Monmouth County?Yes. New Jersey strictly limits plea bargaining in DWI cases, which makes a strong defense even more important.
