If the officer determines that there is probable cause to determine that the person driving or operating a vehicle is legally impaired as a result of being under the influence of alcohol or drugs then he will proceed to arrest and take you to the station. Once at the station you will be required to give a breath or blood sample for a chemical test to determine the alcohol and/or drug content of your blood. Failure to do so will result in further charges for “refusal” which carries additional penalties and a one-year loss of license. When you drive on a public street or highway, in Virginia, you are implying that you consent to providing a breath and/or blood samples for alcohol or drug content. The result of this test can be used in evidence in any prosecution for DWI.
