Twenty-Year-Old, One Beer, and a Checkpoint
Ethan is 20, has a NH driver license with a motorcycle endorsement, and rides a 650 cc bike. He goes to a concert, drinks one 12-ounce beer at 9:00 p.m., eats dinner, and leaves at 10:30 p.m. He weighs 160 pounds, feels alert, and has no trouble balancing. He is stopped at a checkpoint two miles from the venue. The officer smells alcohol and asks him to perform field sobriety tests and take a breath test. Ethan says he had only one beer and asks whether he is legally okay to ride. His license, registration, and insurance are valid; his bike has a legal muffler and mirror. He has no prior offenses.
1. What BAC standard applies to Ethan, and can he assume one beer is safe?
Read the worked answer
Because Ethan is under 21, NH’s zero-tolerance standard applies: a BAC of .02 or higher is illegal for him to operate a motor vehicle. One 12-ounce beer can put a 160-pound person near or over .02 depending on timing, food, and metabolism. The 90 minutes may reduce his BAC, but it does not guarantee he is under .02. Feeling alert and balancing well are not defenses. The safe choice is not to ride after drinking; he should use a sober ride.
2. What happens if Ethan refuses the breath test?
Read the worked answer
By operating a motorcycle on NH public roads, Ethan is subject to implied consent for chemical testing. Refusing the breath test can trigger an administrative license suspension and other penalties even if he is not convicted of DUI. Field sobriety tests are a separate issue, but refusing the chemical test carries its own consequences. He should not try to avoid the checkpoint by refusing without understanding the administrative risk.
3. If his breath test shows .03, what is the likely legal result?
Read the worked answer
A .03 result is below the adult DUI per se limit of .08, but Ethan is under 21, so the zero-tolerance standard applies. A .03 BAC would support an under-21 alcohol violation and likely license suspension, fines, and possibly alcohol education. It is not the same as an adult DUI charge, but it is still a violation. His clean record may affect penalties, but it does not change the .02 standard.
