What happens if a driver refuses both chemical tests after a DWI arrest?

If a driver refuses both chemical tests following a DWI arrest, the state’s implied consent laws generally come into play. Under these laws, when a driver operates a vehicle on public roads, they are presumed to have consented to chemical testing for alcohol or drugs if arrested for DWI. Refusal to take these tests typically results in administrative penalties rather than criminal charges.

In Missouri, refusing both chemical tests can lead to an automatic suspension of the driver's license for a specific period, commonly one year. This serves as a consequence to discourage refusal and encourages compliance with chemical testing laws. The intent behind this penalty is to uphold public safety by allowing law enforcement to effectively assess and manage impaired driving.

Other options present consequences that do not align with the standard legal framework regarding refusal of chemical testing, reinforcing that the implication of losing a license for a year is a direct result of such refusals under the law.
