Two Beers at a Village Barbecue and a 45-Minute Drive
You are at a family barbecue in a Guam village. Over about two hours you have had two 12-ounce beers, and you ate a full meal. You feel 'fine' and believe you can drive. You are 45 minutes from home on a mix of village roads and a highway. A cousin offers to drive you, but you do not want to leave your car overnight. You have work at 7 a.m. You are 5 feet 6 inches and weigh about 160 pounds. You have not had water in a while and you are tired from a long week.
1. Evaluate your belief that you are 'fine to drive.' What factors make self-assessment unreliable here?
Read the worked answer
Feeling fine is not evidence of being under the legal limit or safe to drive. Alcohol impairs judgment, coordination, and reaction time before a person notices it, and the impairment that matters most - the ability to judge your own impairment - is itself affected.
Factors that make your self-check unreliable:
- Fatigue: a long week plus alcohol compounds drowsiness and slows reactions.
- Dehydration: worsens fatigue and the effects of alcohol.
- Time and food: a full meal slows absorption but does not eliminate alcohol; two beers over two hours still leaves alcohol in your system, and how much depends on your body and timing.
- 'Fine' is a feeling, not a measurement.
The safe and lawful choice is not to drive. Take the cousin's offer, call a ride, or leave the car and retrieve it later.
2. What are the practical costs of leaving the car overnight versus driving, and how should you weigh them?
Read the worked answer
Leaving the car costs you a ride home, a ride back in the morning, and maybe a parking favor. Driving impaired risks a DUI arrest, license consequences, crash injury, and harm to others - costs that dwarf a morning inconvenience.
Weighing them: the inconvenience is certain but small and recoverable. The risk of driving is uncertain but severe and irreversible. When the downside is catastrophic and the upside is saving 45 minutes, the rational choice is to leave the car.
Plan: accept the cousin's ride or call a sober driver, arrange to return for the car in daylight, and tell your workplace you may be a few minutes late if needed. Do not 'wait an hour and see how you feel' as a substitute for a sober ride.
3. If you had driven and were stopped, what would the officer likely be looking for, and why does 'I only had two beers' not settle it?
Read the worked answer
An officer looks for driving behavior (weaving, slow response to signals, wide turns), then for physical signs (odor, bloodshot eyes, slurred speech, fumbling with documents), then for performance on field sobriety tests and a chemical test.
'I only had two beers' does not settle anything because:
- Drink size and alcohol content vary; a 'beer' may be more than 12 ounces or stronger than expected.
- Body weight, food, hydration, fatigue, and time all change the effect.
- The legal question is measured impairment, not a count of drinks.
The takeaway: do not use a drink count as a license to drive. Use a sober ride.
