In some states, DWI (driving while intoxicated) and DUI (driving under the influence) are terms that carry different meanings or imply varying degrees of impairment. However, in New Jersey, this distinction does not exist. The state uses these terms interchangeably to describe the offense of operating a vehicle under the influence of alcohol or drugs.

Regardless of whether the term DUI or DWI is used, the law focuses on the impairment of the driver’s ability to operate a vehicle safely. New Jersey law, specifically under N.J.S.A. 39:4-50, states that a person is guilty of a DUI/DWI if they operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher. But it is not just alcohol that can lead to a DUI/DWI charge; impairment due to prescription medications, illegal drugs, or even over-the-counter medications can also result in a DUI/DWI charge.
