Impairment
Well known is the fact that the consumption of alcohol can cause impairment. Perhaps less recognized is that fact that impairment rises gradually at lower levels but dramatically at higher levels of blood alcohol concentration (BAC).
Alcoholism
Alcoholism, also known as “alcohol dependence,” Includes four symptoms: Craving: A strong need, or compulsion, to drink. Loss of control: The inability to limit one’s drinking on any given occasion. Physical dependence: Withdrawal symptoms, such as nausea, sweating, shakiness, and anxiety, occur when alcohol use is stopped after a period of heavy drinking. Tolerance: The need to drink greater amounts of alcohol in order to “get high.”
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.
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.
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.
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.
Sleep Deprivation
Drowsy driving is greatly under reported because there is no test for it, as there is for intoxication, no clear way to identify it, and many states don't even have a code for it on their vehicle accident reporting forms.
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.
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.
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.
