New Jersey laws regarding driving while intoxicated (DWI) include the act itself and multiple related offenses, including driving while one’s license is suspended (DWLS) and refusal to submit to breath testing. State law imposes harsher penalties for second and subsequent offenses, but it also mitigates these penalties in some situations. Merely having prior convictions therefore does not necessarily mean that a defendant must receive an enhanced penalty. A decision from the New Jersey Appellate Division in September 2015, State v. Jones, involved a defendant with a particularly complicated history of prior convictions. This made determining a proper sentence quite difficult.The Jones case involves all three types of offenses commonly associated with DWI: DWI itself, DWLS, and refusal. DWI and refusal are both considered traffic offenses under New Jersey law rather than criminal offenses. The penalty for a first-time DWI offense is based, in part, on the defendant’s blood alcohol content (BAC). A second offense may involve a higher fine, a jail term, and the installation of an ignition interlock device, regardless of BAC. For a third or subsequent offense, the potential fine and jail term are even higher, also regardless of BAC. A DWI at any level leads to a mandatory period of a driver’s license suspension. DWLS can become a criminal offense in certain situations, partly based on the number of prior DWI convictions, with a mandatory 180-day jail sentence.
New Jersey courts have established certain requirements for guilty pleas in DWI cases, largely due to the potentially unforeseen consequences of pleading guilty with prior convictions. One very important rule, established by the New Jersey Supreme Court in 1990 in State v. Laurick, states that a prior conviction may not be used to enhance a subsequent jail sentence if the prior conviction violated a defendant’s constitutional rights. The most common way defendants use this rule is when they did not have counsel for a prior guilty plea. Another case from the New Jersey Supreme Court, 1989’s State v. Barboza, established minimal standards for the entry of a guilty plea by an uncounseled defendant.
