Attorney Kyle D. Macci has been defending Connecticut DUI clients since 2006. He is not only an experienced criminal defense attorney — he is a former law enforcement officer who spent over 20 years with the New Britain Police Department. He has personally conducted DUI traffic stops, administered Field Sobriety Tests, documented arrest reports, and processed DUI cases from the law enforcement side of the equation. That experience is now entirely in your corner.
This is where Attorney Macci’s combination of law enforcement training and nearly two decades of legal experience creates an advantage that most Connecticut DUI defendants never get access to.
BAC evidence is not bulletproof. The prosecution’s chemical test results are only as reliable as the science, the equipment, and the procedures behind them — and Attorney Macci scrutinizes all three. Specifically, he applies and evaluates the following recognized scientific defense methodologies in every DUI case:
Attorney Macci is trained in the forensic technique of calculating what a defendant’s BAC actually was at the time of driving, working backward from the time the chemical test was administered. Because alcohol is absorbed and eliminated from the body at measurable, scientifically established rates, a BAC reading taken 45 minutes or an hour after a stop may bear no reliable relationship to the BAC at the moment the vehicle was operated. Attorney Macci applies Widmark’s Formula and related pharmacokinetic principles to challenge whether the prosecution’s test result accurately reflects the defendant’s condition at the time of the alleged offense.
Alcohol absorption is not instantaneous. After consuming alcohol, a person’s BAC continues to rise for 30 minutes to two hours before peaking. If a driver was stopped shortly after drinking and tested later at the station, the BAC at the time of testing may have been substantially higher than it was while driving. This is a scientifically validated defense that Attorney Macci pursues aggressively when the timing of a stop and the timing of testing create a gap that the prosecution cannot bridge.
If the officer determines there is probable cause, you will be placed under arrest and advised of your Miranda rights. You have the right to remain silent. Use it. Do not answer questions without an attorney present. Attorney Macci’s consistent advice: be respectful, do not resist, and say nothing beyond identifying yourself.
Every breathalyzer device used in Connecticut must be regularly inspected, calibrated, and maintained according to strict protocols. Attorney Macci subpoenas calibration logs, maintenance records, and inspection certificates for the specific device used in your arrest. A device that was out of calibration, improperly maintained, or operated by an officer without current certification produces results that can be challenged for admissibility.
Standard breathalyzer devices convert breath alcohol into an estimated blood alcohol level using an assumed ratio of 2,100:1 — meaning the device assumes there are 2,100 milliliters of lung air for every milliliter of blood. This ratio varies significantly from person to person based on body temperature, lung capacity, and individual physiology. A defendant whose actual partition ratio differs from the assumed standard may have received a falsely elevated BAC reading. Expert forensic toxicology testimony can establish this variance and undermine the prosecution’s BAC evidence.
Breathalyzer results can be significantly distorted by residual alcohol in the mouth rather than deep lung air. This can result from belching, acid reflux, GERD, dental work, mouthwash, or certain medications. Connecticut protocols require officers to observe a defendant for a mandatory period before administering a breath test specifically to guard against mouth alcohol contamination. Failure to maintain that observation period is a direct procedural violation that Attorney Macci will pursue.
Certain medical conditions can produce falsely elevated BAC readings entirely independent of alcohol consumption. Diabetes and hypoglycemia can cause the body to produce isopropanol and acetone compounds that breathalyzer devices may register as ethyl alcohol. Ketogenic diets produce similar compounds. GERD and acid reflux introduce stomach alcohol vapors into the breath sample. Attorney Macci works with forensic toxicologists and medical experts to document and present these conditions when relevant to a client’s case.
When blood is drawn and tested, the integrity of that sample depends entirely on how it was collected, stored, labeled, transported, and analyzed. A sample drawn with a contaminated kit, stored at improper temperature, or mislabeled in the laboratory can ferment — artificially producing alcohol and inflating BAC results. Attorney Macci demands full chain of custody documentation and laboratory protocols in every blood test case and retains independent forensic analysis when warranted.
The Standardized Field Sobriety Tests recognized by NHTSA — the Horizontal Gaze Nystagmus, Walk and Turn, and One Leg Stand — are only scientifically validated when administered exactly as trained. An officer who modified instructions, conducted tests on an uneven surface, failed to account for a defendant’s footwear, age, weight, or physical condition, or scored the tests inaccurately has produced results that are not scientifically reliable. Because Attorney Macci administered these tests as a working law enforcement officer, he evaluates the officer’s performance with a level of precision that most defense attorneys simply cannot replicate.
As a former law enforcement officer, Attorney Macci also knows precisely what documentation a DUI arrest must generate — what footage should exist, what calibration records are mandatory, what notification requirements apply, and what procedural steps cannot be skipped. When evidence that should be in a file is absent — whether a camera recording, a calibration certificate, a required observation log, or a training certification — Attorney Macci recognizes the gap immediately. An unexplained absence of required evidence is not a minor administrative oversight. It is a potential basis to challenge the prosecution’s entire case, and it will be pursued accordingly.
Understanding the process is your first line of defense. Here is what a DUI arrest in Connecticut generally looks like — and where Attorney Macci’s law enforcement background gives you a critical advantage at every stage:
A law enforcement officer pulls you over based on observed driving behavior or a traffic violation. The legal question is whether that stop was constitutionally justified. Attorney Macci knows what officers are trained to look for to establish probable cause — and he knows when a stop crosses the line from lawful to pretextual.
The officer may ask you to perform Standardized Field Sobriety Tests the Walk and Turn, the One Leg Stand, and the Horizontal Gaze Nystagmus test. Attorney Macci administered these tests during his law enforcement career. He knows exactly how they are supposed to be conducted, how they are scored, and how often they are improperly administered. A test not conducted strictly according to the National Highway Traffic Safety Administration’s standardized protocols may be challenged and suppressed.
If the officer determines there is probable cause, you will be placed under arrest and advised of your Miranda rights. You have the right to remain silent. Use it. Do not answer questions without an attorney present. Attorney Macci’s consistent advice: be respectful, do not resist, and say nothing beyond identifying yourself.
Connecticut operates under an implied consent law. By driving on a Connecticut road, you have legally consented to chemical testing if lawfully arrested for DUI. Refusal carries automatic license suspension consequences separate from the criminal charge itself. However, the administration and calibration of breathalyzer equipment, the chain of custody for blood samples, and the handling of urine tests all present legitimate legal challenges that an experienced attorney can and will pursue.
You will be transported to a police station, processed, and depending on circumstances, held until bail is posted or released on a promise to appear.
A DUI charge in Connecticut triggers both a criminal court case and a separate DMV administrative hearing concerning your driving privileges. Both have strict deadlines. Missing a DMV hearing deadline can result in an automatic license suspension regardless of what happens in your criminal case. Attorney Macci handles both simultaneously.
A Connecticut DUI conviction carries serious consequences that extend far beyond the courtroom:
If you hold a professional license — as a nurse, physician, pharmacist, teacher, contractor, or law enforcement officer — a DUI charge carries consequences that go well beyond the criminal case. Many licensing boards require self-reporting of arrests. Failure to report can result in license discipline separate from and in addition to any criminal punishment. Attorney Macci coordinates his DUI defense strategy with the licensing implications from the very beginning, protecting both your freedom and your career simultaneously.
Attorney Macci also proudly offers special consultation rates for veterans and active military personnel. A DUI charge can jeopardize security clearances, military careers, and veterans’ benefits. His own U.S. Army background gives him a firsthand understanding of the unique stakes that service members face.
A DUI arrest does not have to define your future. The right defense strategy — built early, built on real knowledge of how these cases are investigated and prosecuted — can make all the difference between a conviction and a dismissed or reduced charge.
I have been on both sides of a DUI stop. I know how officers build these cases because I built them myself. I know what the science says, I know where the evidence breaks down, and I know how to take it apart piece by piece in defense of my clients.
