New Jersey law imposes a wide variety of penalties for the traffic offense of driving while intoxicated (DWI). Some of these penalties, like fines and jail time, are primarily punitive. Other penalties have the additional goal of public safety. A license suspension after a DWI certainly counts as punishment, but proponents of license suspensions often cite the public safety benefit of keeping DWI offenders off the roads. A similar justification accompanies the New Jersey law requiring the use of an ignition interlock device (IID), which requires the driver to submit a breath sample and prevents a vehicle from starting if the sample shows a blood alcohol content (BAC) above a certain amount. The Centers for Disease Control and Prevention (CDC), a federal agency, recommends the expanded use of IIDs, based largely on its assessment of the benefit to public safety. A bill currently pending in the New Jersey Legislature would require the installation of an IID for all DWI convictions.
Under current New Jersey law, the penalty for a first-time DWI offense does not include mandatory IID installation if the defendant’s BAC was less than 0.15 percent. Municipal court judges still have discretionary authority to order IID use in such cases during the period of the driver’s license suspension, and for six to 12 months after the reinstatement of the license. For a first offense with a BAC of 0.15 percent or higher, IID installation is mandatory for a similar period of time. After a second or subsequent DWI offense, IID installation is mandatory during the suspension period and for one to three years afterwards.
A DWI defendant cannot drive any vehicle other than the one with the IID installed while they are subject to a court order requiring an IID. Failing to install an IID as ordered, or operating a vehicle equipped with an IID by having someone else blow into the device, can result in an additional one-year license suspension. Other IID-related offenses include blowing into someone else’s IID to allow them to start the vehicle, tampering with an IID, and knowingly lending or leasing a vehicle without an IID to someone subject to a court order requiring an IID. These are all disorderly person offenses, which can carry penalties of up to six months in jail and a maximum fine of $1,000.
