What is implied by the 'implied consent' law?

• A. It means you must carry a special license when driving on highways.
• B. By driving, you agree to be tested for alcohol or drugs if suspected of DUI; refusing can result in penalties.
• C. It only applies to commercial drivers.
• D. It allows drivers to refuse testing without penalties.

Answer: (B)

Implied consent means that by driving on public roads, you automatically agree to submit to chemical testing for alcohol or drugs if a law enforcement officer has reasonable cause to suspect you’re impaired. The test (breath, blood, or urine) is part of the consent tied to driving. If you refuse the test, penalties typically follow—most often an administrative suspension of your license and potential additional charges—regardless of whether you’re ultimately convicted of DUI. This applies to all drivers who are lawfully detained for suspicion of impairment, not just commercial drivers, and it does not authorize refusing without consequence. The point is that driving gives the state the authority to require testing, and refusing carries consequences.
