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 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.
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
