Challenging Blood And Breath Test Evidence In Court

When a police officer pulls you over because they suspect that you’re driving under the influence of alcohol or drugs, after a field sobriety test, they often will conduct a test to determine your blood alcohol content (BAC). This measures how much alcohol is in your body, and you can be arrested if you are driving with a BAC of 0.08 percent or higher. Breath, blood or urine tests are used to determine your BAC, but they are not foolproof. The results can be skewed by a number of factors, including incorrect administration of the tests.

How Does BAC Testing Work?

Blood alcohol tests can be administered by blowing into a breathalyzer, having blood drawn or submitting a urine sample. Breathalyzers are the most common method and can be administered during the traffic stop. They work by identifying the percentage of alcohol in your breath; however, a variety of factors can influence the results including officers improperly administering the test. Also, the tests must be confirmed by administering a second, more accurate breathalyzer at the police station.

Blood and urine tests are taken at a police station and measure the amount of blood in your system. Blood tests are considered the most accurate. However, they require the person administering the test to stick a needle into your arm and draw blood, a procedure that most people choose to avoid. Urine tests can give false readings because it takes over an hour for alcohol to show up in one’s urine, so the test doesn’t fully identify your blood alcohol content at that exact moment in time.
