!! CAUTION - Driving Ability Impaired !!
You can be prosecuted in Connecticut without driving while you are over the legal prescribed bac limit.
Under Connecticut law, it is unlawful to drive with a BAC limit above the per se laws OR to drive while impaired under the influence of alcohol and/or drugs.
Under this law the prosecution must show that the driver was IMPAIRED by alcohol and/or drugs. The level of impairment is usually based on observations and evidence of driving ability (or rather inability), physical appearance, field sobriety tests and any other relevant evidence which can help prove a persons driving ability was indeed impaired. Different amounts of alcohol can affect people in different ways, what may impair one persons driving ability and make them feel drunk, might not necessarily impair another persons driving ability.
Observations from a law enforcement officer that may lead to being stopped and arrested include:
- Making a turn too widely or narrowly
- Using two lanes, stradling the center line
- Almost hitting someone or something
- Weaving or drifting from one side of the road to another
- Driving too slowly and being overly cautious
- Driving too close to vehicle in front
- Driving ON the center lines
- Erratic braking
- Swerving to correct course of vehicle
You can be charged with an offence regardless of your BAC level, as long as impairment can be proved to the legal extent necessary.
