What is a possible consequence of refusing to allow an officer to test for alcohol or drugs?

Refusing to allow an officer to test for alcohol or drugs can lead to the revocation of your driver's license. When a driver is stopped under suspicion of driving while impaired, law enforcement has the authority to request chemical tests to determine blood alcohol concentration (BAC) or the presence of drugs. In Missouri, implicit consent laws mean that by obtaining a driver's license, a person agrees to submit to these tests if requested.

If a driver refuses this request, they face immediate legal repercussions, one of the most significant being the revocation of their license. This revocation typically occurs as part of administrative penalties, separate from any criminal charges that might result from an impaired driving incident. The duration of the license revocation can vary based on prior offenses and the driver's circumstances, which further emphasizes the importance of complying with testing when requested by law enforcement.
