Which statement about implied consent in DUI enforcement is correct?

• A. Implied consent means a driver must explicitly agree to testing.
• B. By driving on public roads, a driver consents to chemical testing; refusal can result in license consequences.
• C. Consent only applies if the driver is arrested.
• D. Consent is granted by the vehicle owner.

Answer: (B)

Implied consent means that when a driver operates a vehicle on public roads, they have given consent to chemical testing for impairment if lawfully arrested for DUI. The important point is that this isn’t about an explicit agreement; to use the roads is to accept the test as a condition of that privilege. If the driver refuses the test, the state typically imposes license penalties, such as an administrative suspension or other license consequences, regardless of the eventual criminal outcome. This option correctly captures both the presumption of consent by driving on public roads and the potential license-related penalties for refusal, which are central aspects of implied consent laws in DUI enforcement.
