DUI/DWI Terms and Definitions

Child endangerment
Most states now have some kind of child endangerment statute. Currently, 27 states have statutes that create special sanctions for cases of driving under the influence while the offender is transporting a child at the time of the offense.

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%.

Boaters Intoxication
Drinking While Boating Open containers are legal, but operators of boats are subject to boating while intoxicated laws, similar to driving a vehicle. Operators or passengers may also be subject to public intoxication laws

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.

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.

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.

Vehicular Homicide
Vehicular homicide is the killing of another person by one’s unlawful or negligent operation of a motor vehicle.

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

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.
