Final answer:
When a driver refuses a chemical test, their driving privileges are often revoked for a period that can vary by state. A common period for a first offense is typically 1 year. Subsequent offenses may result in longer revocations.
Step-by-step explanation:
When a driver refuses to submit to a chemical test, driving privileges may be revoked or suspended. The specific duration of revocation can vary depending on the state's laws; however, a common period for a first offense might be 1 year.
Subsequent refusals or offenses could lead to longer revocation periods or different penalties. It's important for drivers to understand the implied consent laws that they agree to by using state roads, as these laws often include the stipulation that refusal of a chemical test will result in automatic penalties.
