Blood Alcohol Content (BAC)
DUI Attorney Serving Chicago, McHenry County and Surrounding Areas
Mr. Hanaford has been certified through the National Highway Safety Administration (NHTSA) Standard Field Sobriety Testing course. This is the same program in which all qualified DUI police officers receive training. NHTSA sets the national standard for administering field sobriety tests that police officers are expected to follow—but often do not.
Measuring Blood Alcohol Content
Blood Alcohol Content (BAC) is a measurement commonly used to determine whether a person has been driving under the influence. A person’s BAC depends on a number of factors, including how much and how fast they drink, as well as their weight and how much food they have consumed. In Pennsylvania, a person who has a BAC of 0.08 percent or more is considered legally impaired and unfit to drive. A person whose BAC registers between 0.05 percent and 0.08 percent may also be charged with driving under the influence, if the driver’s behavior suggests that he or she is impaired. There are a number of tests that police officers and prosecutors use to measure a driver’s blood alcohol content. These include a roadside breathalyzer test, in addition to a blood, breath, or urine chemical examination following an arrest. If you are pulled over by a police officer under suspicion of DUI, you are not required to submit to a breathalyzer test. You can also decline to participate in a field sobriety test, in which an officer may ask you to perform basic physical tasks to gauge your impairment.
If you have been arrested and charged with DUI, however, the state’s implied consent law obligates you to submit to a chemical BAC test. A person who is arrested for DUI and refuses to take the chemical test faces a license suspension of up to one year for first offenders. If you take the test and fail it, your driver’s license will be suspended for at least six months.
BAC tests raise a number of legal questions about when and where an officer can conduct a traffic stop and ask a driver to submit to an examination. There are also various scientific questions related to the accuracy and reliability of BAC tests. In some cases, for instance, it has been found that drivers with diabetes, gastrointestinal problems, or blood clots may falsely test positive for impairment when they have not been drinking. Testing equipment must be properly maintained, and examination administers must follow certain steps to ensure that the results are precise. If they fail to do so, the test results may not be admissible in court.
