If Texas suspends your license for driving under the influence, you’ll have to purchase Texas DUI insurance to reinstate it. Texas has stiff penalties for alcohol-related motor vehicle offenses. Consequences include jail time, fines and driver’s license suspension. If an officer pulls you over for suspected DUI, and your blood alcohol content (BAC) level of 0.08% or higher, the state will charge you with drunk driving. For commercial drivers and drivers under the age of 21, the blood alcohol content for a DUI charge is 0.04% or greater.
