Final answer:
If you refuse to take a BAC test, you can lose your license for several months to a year, depending on local laws.
Step-by-step explanation:
If you refuse to take a BAC test, you will lose your license for at least several months to a year, depending on the laws of your jurisdiction. In many places, refusing a BAC test is considered a violation of implied consent laws, which means that by driving on public roads, you have already given your consent to be tested for alcohol or drugs if requested by law enforcement. As a result, your license can be suspended or revoked for refusing to take a BAC test, even if you are not guilty of driving under the influence.
