In Pennsylvania, driving with a blood alcohol content (BAC) of 0.08 or higher is illegal and will result in a charge of driving under the influence (DUI) or driving while intoxicated (DWI). When you drink an alcoholic beverage, the alcohol gets into the bloodstream, flows to the lungs and exits your body when you exhale.
A breathalyzer measures the amount of alcohol exhaled by your lungs when you breath into it. It is registered by the machine, which calculates your BAC. If it calculates it at 0.08, this will be used in court as evidence that you were driving under the influence.
Many people think that if they are stopped by law enforcement for suspicion of DUI/DWI, it will help them to refuse a breathalyzer test so there will not be evidence of their BAC. This is not true. If you have been arrested for drunk driving, there are penalties imposed for refusing to submit to the test even if the DUI/DWI charges are later dropped or you are acquitted.
Consequences for Refusing a Breathalyzer Test
According to Pennsylvania law, “Any person who drives, operates or is in actual physical control of the movement of a vehicle in this Commonwealth shall be deemed to have given consent to one or more chemical tests…” in order to determine the blood alcohol content (BAC). The consent only comes into play if you are actually arrested and then requested to take the breath test.
If you refuse to submit to the breathalyzer test, you will have your driver’s license suspended for a period of time ranging between 12 and 18 months, depending on whether or not the driver’s license has previously been suspended under this code section. Even if you are not charged with a DUI, or are charged and acquitted, the refusal is a separate offense and your driver’s license will still be suspended.
Law enforcement also has other ways of proving your BAC was over 0.08. They can testify that your eyes were red, you were driving erratically, your speech was slurred and present other evidence of this nature. This testimony at trial may be enough to secure a conviction even without a BAC test.
Plus, it is not a slam dunk that you will be convicted of DUI even if the results show your BAC to be 0.08 or above. There are challenges that can be made that may show the results to be invalid.
Challenges to the Validity of Breathalyzer Test Results
Certain guidelines must be legally followed for the administration of a Breathalyzer test. If these guidelines were not followed, then the test results will be invalid. Challenges that may be made include:
- You were not observed by a law enforcement officer for 20 minutes prior to the administration of the test.
- The administrator of the test was not properly certified.
- The machine was not properly calibrated.
- There were not two consecutive tests conducted.
- The test was not properly administered.
Even if none of these challenges are successful and the results are not invalidated, there are conditions that may result in a false positive.
Breathalyzer Tests and False Positives
During the 20 minutes of observation prior to the administration of the test, if you ate a breath mint, ingested any alcohol, vomited or smoked, the test will not be valid. Other medical conditions that may result in a false positive include:
- Experiencing a hypoglycemic episode, such as diabetics or those with kidney or liver disease.
- Having ingested cough medicine containing alcohol.
- Using numbing spray or gel containing alcohol as medication for a toothache.
- Being on a high-protein, low-carbohydrate diet.
- Using a hand sanitizer that contains alcohol.
Get Legal Help to Fight Your DUI/DWI Charge
A conviction for drunk driving has significant consequences. It can affect your future ability to get a job and, if you are a divorced or divorcing parent, it can cause you problems with child custody and visitation. If you have a prior DUI conviction, or anyone was injured as a result of your DUI, the penalties will be even greater.
