DUI/DWI Terms and Definitions

 
 

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

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.

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.

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.

OUI
OUI is operating or attempting to operate a motor vehicle while under the influence of intoxicants. "Intoxicants" are any substance, including alcohol and both illegal and prescription drugs. A person is "under the influence" if their mental or physical faculties are impaired to the slightest degree, regardless of whether it affects the a actual operation of the vehicle.

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.

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."

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.

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.

Did You Know?    
 
 
A well known is the fact that the consumption of alcohol can cause impairment
Perhaps less recognized is that fact that impairment rises gradually at a lower level but dramatically at a higher level of blood alcohol concentration BAC. About half of auto fatalities involve drivers with BACs of .16 or higher. Impairment occurs at a lower level, but it's especially important to prevent driving with high BACs.
