DUI/DWI Terms and Definitions

DUI
DUI is driving under the influence; it is the offense of operating a motor vehicle in a physically or mentally impaired condition, especially after consuming alcohol or drugs. Generally, this is a lesser offense than driving while intoxicated.

Drunk
Intoxication as we know it is not required for one to be guilty of drunk driving. Your condition may be enough for you to be found guilty of a drunk driving offense under the current definition of the law.

Public Intoxication
Public intoxication is the appearance of a person who is under the influence of drugs or alcohol in a place open to the general public. In most American jurisdictions, public intoxication is considered a misdemeanor

B.A.C.
B.A.C. is an acronym for Blood Alcohol Concentration. The most definitive way to test for B.A.C. is to test blood. The most common testing method is to take samples of breath (most usually in New Jersey with a “Breathalyzer”). The alcohol in the breath is mathematically converted to a blood alcohol reading.

Horizontal Gaze Nystagmus (HGN)
Horizontal gaze nystagmus is a naturally occurring involuntary jerking of the eyeballs as they gaze side to side. It is theorized that when a person is impaired by alcohol, the nystagmus (the jerking of the eyeballs) is magnified or pronounced.

Failed Sobriety Test
A sobriety test is a method of determining whether a person is intoxicated. Among the common sobriety tests are coordination tests and the use of mechanical devices to measure the blood alcohol content of a person’s breath sample.

Drunk driving penalties
penalties the court could impose are: (1) 6 months in the county jail: (2) $1,000 fine plus up to an additional 1,950 in penalty assessments; (3) 6 months driver's license suspension; (4) Your car impounded for 30 days. Second, third and fourth offenses within 7 years are punished by increasingly more harsh penalties.

Breathalyzer
Breathalyzer is the trademark (of National Draeger, Inc. which acquired the Breathalyzer division from Smith and Wesson) for the most commonly used breath-testing device in New Jersey. The Breathalyzer converts breath alcohol into a blood alcohol reading.

DWI
Driving while intoxicated is the offense of operating a motor vehicle in a physically or mentally impaired condition after consuming enough to raise one’s blood alcohol content above the statutory limit, or after consuming drugs. Penalties for this offense vary widely.

Legal State Limits
Laws for DWI and DUI vary from state-to-state. There is a chart listing state blood alcohol limits, license suspension, ignition interlock and forfeiture penalties.
