Connecticut DUI Law and Penalties

Connecticut DUI law and penalties

Each State in the United States is given the authority to write their own laws on Driving Under the Influence of alcohol, or better known as DUI. Within this article, we will explore the different DUI laws within the specific State of Connecticut, and their penalties. To begin with, there is what is known as a "Lookback Period" of ten years prior to the current DUI you are facing, any DUI's you may have are included in the relevancy of sentencing you are currently facing. This is also known as a "washout" period. 

What constitutes a high BAC for a DUI in Connecticut?

  • Under 21: .02%
  • 21 or Older: .08%
  • Commercial: .04%

There is never an acceptable time to drink and drive, as your vision, responses, along with your mental capacity to make quick and important decisions and judgments, are severely hindered and are not capable of bouncing back to what you are able to perform without alcohol in your system. Each person is different, and their tolerance level for alcohol is severely unpredictable making it impossible to say how many drinks are "normal" or not. This is what requires law enforcement to perform chemical testing on suspected DUI offenders. If you are pulled over and requested to take a chemical test to determine your BAC, or Blood Alcohol Content, Connecticut has an implied consent law. That means that if you refuse to submit to a chemical test you will be subject to a fine and automatic license suspension. For refusal to take the chemical test, the penalties will be as follows: 

  • First Offense: 6 months license suspension
  • Second Offense: 1 year license suspension
  • Third Offense: 3 years license suspension
