Blood, Breath & Field Sobriety Tests

When a police officer suspects a person of driving under the influence of alcohol, they will perform a blood test, a breath test, or a field sobriety test to determine whether or not the driver is over the legal limit. Although each test has its positives and negatives, there are certain tests that are more accurate than others, as your Scranton criminal attorney will explain. If you or a loved one has taken a blood, breath, or field test, and were charged with drunk driving because of the results from those tests, you should speak with an attorney from our firm.

Blood Tests & Breath Tests

Blood tests and breath tests are considered to be relatively accurate ways of determining a person's blood alcohol content (BAC). With blood tests, a sample of the suspected driver's blood will be taken and tested to find out the percentage of alcohol present in the blood. With breath tests, a Breathalyzer machine will be used to take a sample of air from the suspect's lungs. The test will measure the concentration of alcohol in the air of the person's lungs, which is directly related to the concentration of alcohol in the blood. Although these testing measures are somewhat accurate, there are many variables that can contribute to an inaccurate reading, so it is important to have an experienced Wilkes-Barre DUI attorney to examine the testing method and the results to find any mistakes that might have been made.

Field Sobriety Tests

After stopping a driver for suspected DUI, some police officers in Scranton or Wilkes-Barre may require the driver to perform a field sobriety test. There are several different testing methods that may be used by the officer to give them an idea of whether or not the driver's motor functions have been impaired by alcohol. These tests are not always accurate, and sometimes even a sober driver can have trouble performing them, so your lawyer will need to make sure the test results won't be used to convict you of drunk driving.
