What is a chemical test for a DUI?

A chemical test is a scientific method used by law enforcement officers to determine whether or not a driver is intoxicated. In the state of Texas, a chemical test for a DUI (driving under the influence) often includes a breathalyzer or a blood test. A breathalyzer is a device that measures a driver’s blood alcohol concentration (BAC). A driver’s BAC is given as a percentage, and if it is 0.08 or higher, this is considered to be a DUI. In Texas, if a driver refuses to take a breathalyzer test, they face an automatic suspension of their driver’s license. A blood test is a more accurate way to measure a driver’s BAC. Blood tests are usually used in cases when a driver is suspected of being under the influence of drugs or alcohol. The driver may also choose this option instead of the breathalyzer if they do not believe the results of the breathalyzer. In Texas, if a driver is suspected of a DUI, they must comply with the chemical test or face the consequences of refusal. Refusal carries an automatic 180 day suspension of their driver’s license and can be used as evidence in court. A driver who is convicted of a DUI in Texas can also face jail time.
