Under 21, a 0.03 BAC, and a Refusal Question
A 20-year-old driver is stopped at 1:10 a.m. after crossing the center line twice. The officer smells alcohol. The driver admits to drinking one beer about an hour earlier at a friend's apartment and says, 'I'm fine to drive.' A preliminary breath test at the roadside shows 0.03. The driver is under 21. The officer asks the driver to submit to a chemical test at the station. The driver says, 'If I refuse, you can't use the number against me, right?' The passenger says refusal is always better because 'they need the test.' The driver has no prior offenses and is worried about losing the license and a college acceptance.
1. Is a 0.03 BAC legal for this 20-year-old in Kentucky? Explain.
Read the worked answer
No. Kentucky applies a zero-tolerance standard to drivers under 21: a BAC of 0.02 or higher is a per se violation for an underage driver. At 0.03, this driver is above that threshold even though the driver feels fine and even though 0.03 would be below the adult 0.08 limit. The offense does not require the driver to be falling-down drunk or to fail a field sobriety test. The statement 'I'm fine to drive' is not a defense to the underage alcohol violation. The driver should expect the underage BAC evidence to be used in the case.
2. Should the driver refuse the station chemical test? Explain implied consent and evaluate the passenger's advice.
Read the worked answer
The driver should not refuse. Kentucky's implied consent law means that by driving on Kentucky roads, the driver has already agreed to submit to a chemical test when an officer has reasonable grounds to request one. Refusal does not make the evidence disappear; it can lead to license revocation through the implied-consent process and can create additional problems. The passenger's claim that 'they need the test' is wrong in a way that hurts the driver: the prosecution may have other evidence, and the refusal itself can be used administratively against the license. The better course is to comply, stay calm, and address the charges later with a lawyer. Refusing is not a free pass.
3. What should the driver do during the stop, and what should the driver not do?
Read the worked answer
The driver should pull over safely, keep hands visible, be polite, provide the license and registration, and answer basic identifying questions. The driver should not lie about how much was drunk, should not argue about the preliminary result, and should not follow the passenger's advice to refuse testing or to game the stop. The driver can ask about the process and should remember that anything said can be used later. Because the driver is under 21 and already above 0.02, the main damage control is to avoid additional charges and to handle the license consequences properly afterward. The driver should also arrange a safe ride home rather than driving away.
