What will happen if a driver age 21 or older refuses a test to determine blood alcohol content?

If a driver age 21 or older refuses to submit to a test that measures their blood alcohol content, the consequences include a suspension of their driver's license. This is primarily due to the implied consent law in Texas, which stipulates that by operating a vehicle, drivers consent to testing for alcohol or drugs if requested by law enforcement. Refusal to comply with this request results in administrative penalties, such as a license suspension, reinforcing the state's commitment to discouraging impaired driving.

The other options provided do not specifically address the direct consequence of refusing a blood alcohol content test under the law. While there may be broader legal ramifications for driving under the influence or refusing a test, the immediate and concrete result of refusal is indeed the suspension of the driver’s license.
