The U.S. Coast Guard has primary federal authority to enforce BUI laws on the navigable waters of the United States.
Question 4: Compared to driving on land, the effects of alcohol are typically __________ on the water.
- Reduced because boats travel slower
- About the same as on land
- Accelerated by sun, wind, and boat motion (Correct answer)
- Eliminated by fresh sea air
Correct answer: Accelerated by sun, wind, and boat motion
Sun exposure, wind, engine noise, wave motion, and vibration accelerate the impairing effects of alcohol on the water.

- Ability to judge distances and react quickly (Correct answer)
- Ability to read nautical charts
- Ability to anchor precisely
- Ability to identify other vessels by name
Correct answer: Ability to judge distances and react quickly
Alcohol impairs judgment, balance, vision, and reaction time — all essential skills for safe boat operation.
Question 7: A boater who refuses to submit to a law enforcement sobriety test may face:

Correct answer: Automatic penalties including license suspension under implied consent laws
Implied consent laws mean that by operating a vessel, boaters consent to sobriety testing, and refusal typically results in automatic penalties including license suspension.
