The Legal Distinctions Between BUI and DUI

Driving Under the Influence (DUI) and Boating Under the Influence (BUI) are serious crimes in Georgia, each with severe penalties. While both offenses have similar legal standards, such as blood alcohol concentration (BAC) limits and impairment rules, the enforcement and consequences differ based on the situation.

What Is Boating Under the Influence (BUI) in Georgia?

Under O.C.G.A. § 52-7-12, it is illegal to operate any vessel while under the influence of alcohol, drugs, or other intoxicating substances. This law applies to motorboats, sailboats, jet skis, and even human-powered vessels like kayaks and canoes. The BAC limit for recreational boaters is 0.08%, the same as for drivers. For individuals under 21, Georgia enforces a zero-tolerance policy, setting the limit at 0.02%.

BUI enforcement presents unique challenges:

1. Field sobriety tests on water are unreliable due to unstable conditions like waves, heat, and fatigue.
2. Testing often happens onshore, sometimes after a delay, affecting BAC accuracy.
3. Georgia’s Department of Natural Resources (DNR) officers and conservation rangers frequently patrol lakes and rivers. They have broad authority to stop vessels for safety checks, which can lead to BUI investigations.

What Is Driving Under the Influence (DUI) in Georgia?

Under O.C.G.A. § 40-6-391, it is against the law to drive or be in control of a motor vehicle if you:

1. Have a BAC of 0.08% or higher (for most drivers)
2. Have a BAC of 0.04% while driving a commercial vehicle.
3. Are under the influence of alcohol, drugs, or a combination of substances that impair your ability to drive safely

DUI enforcement involves:

1. Traffic stops when officers observe unsafe driving, like swerving or speeding
2. Sobriety checkpoints approved under Georgia law
3. Breath, blood, or urine tests to measure BAC or detect drugs

Why the Difference Matters

Although DUI and BUI fall under different laws, both can have lasting consequences. Convictions can result in a criminal record, impact professional licenses, and hurt future job prospects. Georgia law does not allow DUI convictions to be expunged, and BUI convictions may also be permanent, depending on the circumstances.

1. Field Sobriety Tests (FSTs): Officers conduct tests like the horizontal gaze nystagmus, walk-and-turn, and one-leg stand, accoridng to the National Highway Traffic Safety Administration (NHTSA) guidelines.
2. Breath Tests: Officers use Intoxilyzer 9000 devices for evidentiary breath testing. These machines must meet the calibration and maintenance standards that the Georgia Bureau of Investigation (GBI) set under O.C.G.A. § 40-6-392.
3. Implied Consent Warnings: Officers must read these warnings exactly as Georgia law requires before administering tests.
4. Video Evidence: Dashcam and bodycam footage often document the stop and testing process. This evidence may help verify the officer’s or driver’s actions.

Georgia assigns DUI cases to prosecutors or DUI divisions at solicitor-general offices. These prosecutors receive extensive training and have access to significant resources, which allows them to build strong cases against defendants.

How BUI Enforcement Differs on Georgia Waters

BUI enforcement happens in a much less controlled environment than DUI enforcement. Marine patrol officers, often from Georgia DNR or local sheriff’s offices, can stop boats without prior suspicion by claiming routine safety or registration checks. These stops can quickly turn into impairment investigations if officers notice signs like slurred speech, open alcohol containers, or other evidence of intoxication.

Unlike DUI stops on roads, BUI investigations face many challenges:

1. Testing conditions are unstable due to the movement of watercraft.
2. Officers do not have bodycam or dashcam footage to document interactions.
3. Field sobriety tests are often improvised and subjective.
4. There are often long delays before formal BAC testing, especially when transporting individuals to shore.

These challenges create opportunities for legal defenses. For instance, common conditions on the water, like fatigue, sun exposure, and dehydration, can mimic signs of impairment. Without clear video or roadside-level documentation, defense attorneys can more easily challenge officer observations, testing methods, and whether proper procedures were followed.
