Medical Defense in OUI / DUI Cases

Do you or have you ever had:

A knee injury?

A back injury?

Injury to your legs that could impact balance in a field sobriety test?

We can help you! Because your medical condition can affect the reliability of the breathalyzer test, the impression that the officer may have as to how you performed on the field sobriesty tests, and could help to explain observations of the officer that he or she attributes to being under the influence, medical evidence can assist in defending your Massachusetts OUI arrest.

There are 3 ways to present medical evidence relating to your performance on field sobriety tests:

Testimony from treating doctor

Testimony in the form of a sworn medical affidavit

Through your own testimony explaining the injury or the testimony of someone with knowledge of your injury

An injury could explain an officer’s observations of lack of balance or being unsteady while walking. When you have a medical condition unknown to the officer, a strong argument can be made that the officer could not accurately access your performance without knowing your medical condition and physical limitations.

Medical defense

Medical evidence can also be used at a breathalyzer refusal appeal when an individual has a lower lung capacity or trouble breathing into the machine; in many cases, the officer may attempt to deem this as a refusal of the breath test when a medical condition explains the inability to provide a breath sample. Medical evidence could be offered to contradict the claim that the motorist refused the breathalyzer. This evidence can be presented at the RMV to challenge a license suspension for refusing a breathalyzer test.

Medical defense

Since the accuracy of the breathalyzer machine is dependent on the assumption that the motorist is the normal or average individual, medical conditions sometimes undermine the assumptions made by the breathalyzer machine.

Are you a diabetic? We can help you!

When in a state of ketoacidosis, a diabetic’s blood sugar raises as the body is unable to use carbohydrates as a source of fuel and burns stored fat as fuel and produces ketones.

A breathalyzer machine may wrongfully detect ketones as ethyl alcohol and provide a blood alcohol reading that is falsely elevated

Medical defense

Breathalyzer testing machines are nonspecific for alcohol and do not test specifically for ethanol. There are many industrial compounds that contain a molecular structure similar to ethyl alcohol that a breathalyzer machine mistakes as alcohol.

Other compounds that can cause an artificially high breath result include:

Toluene, which is found in industrial compounds (paint thinner, cleaning agents, and industrial products).

Carpenters, plumbers, janitors, and other manual labors may have been exposed to these compounds, which would be registered as alcohol by a breathalyzer machine.

Client Reviews
Michael was very professional and explained the process clearly and told us to be patient. After one year the charges got dismissed in the trial. Excellent knowledge of the court systems in the area of Boston. Would highly recommend him Ashwani
A careless decision on my part left me facing charges which would have severely hampered my ability to stay employed and support myself. But attorney DelSignore's skillful analysis and challenging of the evidence against me resulted in a conviction on a lesser charge. Now I'll be able to go on with my life, having learned a lesson I'll never forget. Thank you, Michael. Scott
Mike stuck with my case for 3.5 years and always kept me informed regarding the status. Ultimately, because of his due diligence, we ended up with an OUI not guilty verdict. This case could have gone many ways but his thorough review of the case and exceptional preparedness for trial ultimately drove a positive outcome. Thank you Mike! David
Michael DelSignore did an amazing job with my case! He was always available to answer any questions I had and helped walked me through the entire process. I could not have done it without them! I highly recommend choosing this law firm to deal with your legal needs, you will not be dissatisfied. Ashley
I cannot express the gratitude towards Michael for his amazing work and help. It was a very stressful event and they certainly put me at as much ease as possible. From start to finish it took 14 months and all the way through they were both very engaged with me. Today was worth the wait, Michael was great in court and I was rightfully found not guilty. I would recommend Michael over and over again. Claire
