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.
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.
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.
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.
Reasonable suspicion
The officer must have what is legally termed a "reasonable suspicion," based on something unusual that is actually observed about the way a person is driving. This is a very low standard and it can be satisfied by virtually anything which appears out of the ordinary and that might be a sign of a driver being under the influence. In addition, during holiday seasons, police officers typically set up field sobriety checkpoints where they routinely stop every driver who passes through the checkpoint.
Excessive Drunkenness
A state of drunkenness in which a person is so far deprived of reason and understanding that he or she is incapable of understanding the character and consequences of an act.
Ignition Interlock Devices
The courts may require first and repeat DUI offenders to use Ignition Interlock Devices. To start the vehicle, the driver must blow into the device. The vehicle will not start if the driver's blood alcohol content exceeds 0.05%.
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.
Controlled Substances
Health and other public concerns have generated detailed Federal and state regulation of the sale and possession of alcoholic beverages, tobacco products, and a wide range of other "controlled substances."
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.
