What happens if a driver aged 21 or older refuses to determine the amount of alcohol in their body?

When a driver aged 21 or older refuses to submit to a breath or blood test to determine their blood alcohol concentration (BAC), they face a mandatory penalty under Texas law. Specifically, the refusal to test is viewed as an indication of guilt and results in the suspension of their driver license. This law is implemented to encourage compliance with testing and to ensure that drivers are held accountable for their intoxication levels while operating a vehicle.

The suspension typically lasts for a period, depending on whether it is a first refusal or a subsequent one, and reinforces the seriousness of driving under the influence. The consequences of refusal serve as a deterrent, emphasizing the importance of measuring BAC for public safety and legal compliance.
