How Is Blood Alcohol Level Measured After a Boca Raton DUI Car Crash?

If police officers suspect that alcohol may have had any role in causing a Boca Raton car accident, they will order a test of the drivers' blood alcohol concentration.

Blood alcohol concentration (BAC) refers to the amount of alcohol present in a driver's blood stream at a given time.  It is measured in grams of alcohol per deciliter (100 milliliters) of blood and is often expressed as a used as a percentage. In Florida, any driver with a BAC of .08 percent or greater may be charged with Florida DUI. A driver who is using drugs may also be charged with DUI.

There are four main tests used to determine BAC in Florida:

  1. Field sobriety test
  2. Breath test ("breathalyzer")
  3. Blood test
  4. Urine test


Field sobriety tests are used to determine if there is probable cause to arrest a driver for driving under the influence. Field sobriety tests cannot be used if the driver is injured or if the accident scene is unsafe, so breathalyzer tests are more common.

If the driver is injured or a police officer strongly suspects a driver in a Boca Raton car crash has been drinking, the driver will be taken to the hospital for a blood test. Blood tests are more accurate than breathalyzer tests.

The driver may also be given a urine test. While urine tests don't always give an accurate BAC, they can be used to screen for illegal and legal drugs.

If you have been injured in a Florida DUI accident, your Boca Raton car crash attorney will obtain the police report and the results of the other driver's blood alcohol tests. He will use this information to support your Florida injury claim.
