What is an 'implied consent' law?

Correct answer

By driving on public roads, you have agreed to submit to chemical testing (such as breath or blood) for alcohol or drugs if lawfully arrested for impaired driving

  1. A Consent to buy alcohol
  2. B By driving on public roads, you have agreed to submit to chemical testing (such as breath or blood) for alcohol or drugs if lawfully arrested for impaired driving
  3. C Permission to speed
  4. D Consent to park anywhere

Why this is the answer

Implied consent laws provide that by accepting a driver's license and driving on public roads, you have automatically consented to submit to chemical testing — breath, blood, or urine — to measure alcohol or drugs if you are lawfully arrested or detained for suspected impaired driving. Refusing the test typically carries its own penalties, such as automatic license suspension, separate from any DUI charge. These laws support enforcement of impaired-driving statutes. The exact procedures and penalties vary by state, but the concept of implied consent — driving means agreeing to testing when lawfully required — is widely tested.
