Florida’s sun-drenched waterways attract millions of boaters each year. From locals to out of towners, time spent on the water can make for a great day – but when that time includes consumption of alcoholic beverages it is important to know the basics about the laws that govern drinking and boating.
Blood alcohol limits on Florida waterways
Just like operating a motor vehicle on Florida roads, piloting a boat while intoxicated is illegal and dangerous. Florida law establishes a blood alcohol concentration (BAC) limit of 0.08% for vessel operators, identical to the threshold for drivers of cars and trucks. In this way, Boating Under the Influence (BUI) and driving under the influence (DUI) are similar. This standard applies to all motorized watercraft on Florida’s rivers, lakes, coastal waters and intracoastal waterways.
Law enforcement stops: Water vs. road
The procedures governing BUI and DUI stops differ significantly, largely due to the unique environment in which each occurs. Key differences include:
- While officers must have a reason to conduct a roadside stop, Florida Fish and Wildlife Conservation Commission (FWC) officers may board and inspect any vessel on state waters without reasonable suspicion of wrongdoing
- Safety inspections on water are routine and do not require probable cause
- Boaters have fewer Fourth Amendment protections against searches compared to vehicle operators on public roads
These distinctions mean that boaters face a higher likelihood of encountering law enforcement even when operating responsibly, making awareness of BUI laws particularly important for anyone spending time on Florida waterways.
Potential penalties
Even a first time offense can come with serious penalties. This can include up to 6 months imprisonment and a $1,000 fine. A second offense can lead to 9 months imprisonment and a $2,000 fine. These fines can increase under certain circumstances, such as if there was also a crash or a minor in the vessel.
It is also important to note that these penalties can evolve. In a recent example, the state passed increased penalties under what is known as Trenton’s Law. This law doubles the penalties when a BUI case involves repeat charges or an accident that caused a death.
Protecting your rights
Whether you are facing BUI or DUI charges in Florida, it is important to understand your legal rights and the potential consequences. Both offenses carry significant penalties including fines, incarceration, mandatory substance abuse courses and lasting impacts on your personal and professional life. A defense tailored to the specifics of your case can help to mitigate these risks.
