The DWI Law in Texas
Drunk driving is charged as DWI in Texas, at a blood alcohol level of 0.08 or more.
Driving in Texas is consent to a breath or blood test when an officer has cause to suspect DWI; the license case that follows a refusal or a failed test is run by the Department of Public Safety, separately from the criminal case.
Texas sets no time limit on prior offenses: every earlier conviction counts toward a repeat charge.
