DUI/DWI Terms and Definitions

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.”

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.

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.

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.

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.

Field Sobriety Tests
Field Sobriety Tests sometimes referred to by the acronym FSTs, are tests administered by the police to purportedly assess intoxication.

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).

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.

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.

Administrative License Revocation (ALR)
Simply put, the DMV automatically revokes your license when you are arrested for DUI as part of its duty to regulate drivers’ licenses. (The court may also take your license, and may also fine or jail you.)
