Law enforcement may try to obtain evidence to support a DUI case by having a driver submit to a chemical test. A chemical test can consist of blood, breath, or urine tests. Urine and blood tests are very different than Intoxilyzer and Breathalyzer tests, and each one comes with a different set of potential sources for false readings and inaccuracy. Unfortunately, a driver arrested for DUI does not get to choose which test they take. It depends on a variety of factors, such as the circumstances of the arrest and police preferences.

Blood Tests

To obtain an accurate chemical test, blood tests are typically conducted at a police station or hospital. Blood tests are taken by inserting a needle into the driver’s vein and drawing enough blood for a sample. The blood sample is then sent to a laboratory for testing. When administered correctly, the sample can show whether a driver had a blood alcohol concentration (BAC) level of 0.08 percent, the legal threshold in DC, at the time the sample was gathered.

Although blood tests are accepted as the most accurate form of chemical test, this does not mean that someone’s BAC results are accurate. Contacting a DUI lawyer in DC immediately is essential to find out about someone’s legal options.

Breathalyzer Refusal

A person can always refuse to take a breath test but they should know that there are consequences. Before the breath test is administered, a police officer reads an implied consent form telling the person that by obtaining a driver’s license and driving in the District of Columbia, they give their implied consent to take a breath test if they get arrested on suspicion of a traffic alcohol or drugs case.

If the person refuses to take the test, they can lose their license or driving privileges in DC. When the person has a DC driver’s license, their license can be suspended for up to one year.

When someone refuses to take the test, the government can use that fact against the person in court as evidence the person was intoxicated or under the influence.

Urine Tests

Urine tests are deemed the least accurate of all chemical DUI tests. If administered, the driver provides a urine sample while at the police station or hospital. The specimen is then taken to the lab for testing.
