What does California's implied-consent law require of a driver who is lawfully arrested for DUI?

• A. The driver must provide a blood sample only.
• B. The driver must submit to a chemical test; refusal can trigger license suspension and other penalties.
• C. The driver must answer questions about sobriety but not submit to tests.
• D. The driver may refuse without penalties.

Answer: (B)

Implied consent means that by driving, you agree to submit to a chemical test if lawfully arrested for DUI. In California, the test can be a blood, breath, or urine test used to determine alcohol concentration or drug presence. You must comply with the chemical testing request; choosing not to test is not allowed without consequences. Refusing can lead to a license suspension administered by the DMV and may bring other penalties. This reflects how the law supports enforcing DUI laws by ensuring evidence is obtainable, while penalties for refusal deter attempts to avoid testing.
