If your license is suspended after an alcohol-related motor vehicle offense, you’ll have to purchase Texas DUI insurance for license reinstatement. Texas has stiff penalties for driving under the influence. Consequences include jail time, fines and driver’s license suspension. If you’re pulled over and tested with a blood alcohol content (BAC) level of 0.08% or higher, you will be charged 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.
