Quick Answer: Under Indiana Code 35-46-9-6, it is illegal to operate a motorboat with a blood alcohol concentration of 0.08% or higher, or while otherwise impaired by alcohol or drugs. When a boater breaks this law and injures someone on Geist Reservoir or Morse Reservoir, the criminal charge can also serve as powerful evidence in a separate civil injury claim.
By late June, the coves off the Olio Road causeway and the water near Morse Marina are busy from morning until sunset. Pontoons pull up next to wake boats, tubers trade off behind ski boats, and paddleboarders ease through the no-wake zones.
Most days end with nothing more than sunburns and good stories. But every summer, some end in an emergency room, and far too often the cause traces back to an operator who should not have been behind the wheel.
Indiana’s boating under the influence law makes it a crime to operate a motorboat while impaired. What that statute does not do, on its own, is compensate the people who were hurt.
For that, injured boaters and their families turn to a separate civil injury claim, which can use the BUI violation as powerful evidence against the at-fault operator.
Key Takeaways about Indiana’s Boating Under the Influence Laws and Personal Injury Claims
- Indiana Code 35-46-9-6 makes it a criminal offense to operate a motorboat with a BAC of 0.08% or higher or while otherwise intoxicated.
- A criminal BUI case and a civil injury claim are separate proceedings with different goals, different standards of proof, and different outcomes.
- Violation of a safety statute like the BUI law can support a negligence claim brought by an injured person.
- Geist Reservoir and Morse Reservoir are heavily trafficked recreational lakes where alcohol-related boating incidents occur during peak summer months.
- Indiana follows a modified comparative fault rule, which affects how compensation is calculated when more than one party may share blame.
- The civil statute of limitations for most personal injury cases in Indiana is two years from the date of the incident.
What Indiana’s Boating Under the Influence Law Actually Says
Indiana’s boating under the influence law is found in Indiana Code 35-46-9-6. The statute makes it a criminal offense for a person to operate a motorboat in any of the following circumstances:
- With a blood alcohol concentration of 0.08% or higher
- With a Schedule I or II controlled substance or its metabolite in the body
- While intoxicated to the point that there is an impaired condition of thought and action and a loss of normal control of the person’s faculties
A first-time BUI offense in Indiana is typically charged as a Class C misdemeanor. The charge can be elevated to a Class A misdemeanor or a Level 6 felony if the operator has prior convictions.
When a BUI causes serious bodily injury to another person, penalties increase, and a BUI that causes death can be charged as a Level 5 felony.
These criminal consequences exist to punish and deter dangerous behavior, but they do nothing to repay a family for medical bills, lost income, or long-term care needs.
BUI Applies to More Than Just Alcohol
Many people assume BUI is only about beer coolers on the pontoon. The statute is broader than that. Under Indiana Code 35-46-9-2, “intoxicated” also covers impairment from controlled substances, legal prescriptions used improperly, and other substances that affect thought and action.
The law also includes jet skis and sailboats that use a motor. That matters because crashes on reservoirs often involve personal watercraft, and the same rules apply.
By operating a motorboat on Indiana waters, a person gives implied consent to chemical testing when there is probable cause of impairment. That consent is a condition of using the state’s waterways, and refusing a test can carry its own consequences.
Why Geist Reservoir and Morse Reservoir See So Many Boating Incidents
Geist Reservoir covers about 1,900 acres on the northeast side of the Indianapolis metro area, with shoreline in Fishers, McCordsville, and Lawrence. Morse Reservoir sits just to the north near Noblesville and Cicero.
Both are owned by Citizens Energy Group and both serve as community hubs for summer recreation.
On a typical weekend in July, the water near the Olio Road causeway or close to Morse Marina can be packed with pontoons, ski boats, tubers, wake surfers, and jet skis.
Weekend congestion, holiday traffic around Memorial Day, July 4th, and Labor Day, and the presence of waterfront restaurants that serve alcohol all raise the risk of impaired operators being on the water at the same time as families, paddleboarders, and swimmers.
When impairment enters that mix, serious injuries follow.
Common types of incidents on these reservoirs include:
- Collisions between motorboats in no-wake zones or near crowded coves
- Jet ski crashes at high speed
- Passengers falling from tubes or wake boards being struck by propellers
- Boats striking swimmers near docks, beaches, or the Geist Waterfront Park area
- Dockside incidents during loading, unloading, or fueling
After any of these events, the question of who pays for the harm becomes central. That is where the civil side of the law comes in.
The Critical Difference Between a Criminal BUI Case and a Civil Injury Claim
A criminal BUI case is filed by the state against the operator. The goal is punishment, which can include jail time, fines, probation, loss of boating privileges, and even suspension of a driver’s license. The burden of proof is “beyond a reasonable doubt,” the highest standard in the legal system.
A civil injury claim is filed by the injured person against the at-fault operator and, when applicable, their insurance company. The goal is to recover money for losses caused by the crash.
The burden of proof is “preponderance of the evidence,” which means it is more likely than not that the defendant caused the harm. These two cases run on separate tracks:
- A person can be acquitted of BUI and still be found liable in a civil case.
- A person can be convicted of BUI and still fight the civil claim on issues like damages.
- The civil case can move forward even if criminal charges are dropped or reduced.
Injured victims and their families should not wait for a criminal case to conclude before exploring their civil options, because evidence can fade quickly and deadlines are strict.
How a BUI Violation Supports a Civil Negligence Claim
To win a personal injury case in Indiana, the injured person generally must prove four elements of negligence: duty, breach, causation, and damages.
In a boating crash, the at-fault operator’s duty is to operate the vessel with reasonable care and in a way that does not put others in danger.
Indiana recognizes a doctrine called negligence per se. Under this rule, when a defendant violates a safety statute designed to protect the public, that violation can establish the duty and breach elements of negligence.
Indiana’s BUI statute is exactly that kind of safety law. Indiana courts have long applied negligence per se when a defendant breaks a statute written to protect people from harm, and the harm that occurred is the type the statute was meant to prevent.
In practical terms, this means a civil claim arising from a BUI crash on Geist or Morse may be built on:
- The results of any chemical test, such as blood or breath analysis
- Police reports and citations issued at the scene
- Witness statements from other boaters, passengers, or people onshore
- Marina and dock camera footage
- Cell phone records, receipts from lakefront restaurants, or social media posts showing alcohol use before operation
- Expert analysis of the boat’s speed, path, and damage
A closing point here: the BUI arrest is powerful evidence, but it is only one part of a full investigation. Civil attorneys often uncover facts the criminal case never explores, because the two systems ask different questions.
Who Can Be Held Accountable After a BUI Crash
In many crashes, more than one party may share responsibility. A thorough civil claim looks at every possible source of compensation, including:
- The impaired operator of the boat, jet ski, or other watercraft
- The owner of the vessel, if different from the operator, under negligent entrustment principles
- A host or commercial establishment that furnished alcohol in violation of Indiana’s Dram Shop Act when the provider knew the person was visibly intoxicated
- A rental company that failed to follow safe rental practices or skipped required safety checks
A closing thought on accountability: the goal of a civil case is not to punish people out of spite. It is to make sure that those who caused harm, and their insurers, take responsibility for the real costs the injured family is carrying.
What Compensation May Be Available
Boating crashes can produce injuries that are different from typical car wrecks, including near-drowning injuries, propeller wounds, spinal cord injuries, traumatic brain injuries, and fractures from high-speed impacts. A civil claim can seek compensation for losses such as:
- Emergency medical treatment, surgery, and hospital stays
- Follow-up care, rehabilitation, and physical therapy
- Future medical needs, including long-term care
- Lost wages and lost earning capacity
- Pain and suffering
- Emotional distress and loss of enjoyment of life
- Property damage to boats, watercraft, or personal items
When a BUI crash results in a death, Indiana’s wrongful death statute allows certain family members or a personal representative to bring a claim on behalf of the estate.
These cases can recover funeral and burial costs, loss of financial support, and loss of love and companionship, depending on the circumstances.
The compensation available in any individual case depends on the facts, the severity of injuries, available insurance coverage, and Indiana’s comparative fault rules.
Protecting Your Case After a Reservoir Crash
After a boating incident, focusing on medical care is the top priority. At the same time, a few practical steps can help protect a future claim:
- Report the incident to law enforcement and request a written report
- Get medical attention even if injuries seem minor, because adrenaline can mask symptoms
- Take photographs of injuries, vessels, the scene, and any visible damage
- Write down names and contact information for witnesses
- Keep receipts, medical records, and a journal of recovery
- Avoid giving recorded statements to the other boater’s insurance company before talking to a lawyer
Taking these steps early gives your attorney the evidence they need to build a strong case.
FAQs for Indiana Boating Under the Influence Laws
Here are answers to some of the most common questions people have after a BUI-related boating crash on an Indiana reservoir.
Is BUI treated the same as a DUI in Indiana?
They are separate offenses, but they share many features. Indiana’s boating statute has its own chapter of the criminal code, and a BUI conviction can also affect driving privileges in some cases.
What if I was a passenger on the impaired operator’s boat?
Passengers injured by an impaired operator often have a strong claim against that operator’s insurance coverage. Being a passenger does not bar you from pursuing compensation.
What if I was partly at fault, maybe because I was not wearing a life jacket?
Indiana’s modified comparative fault rule allows recovery if you are 50% or less at fault. Your compensation would be reduced by your percentage of fault, but you are not automatically barred from a claim.
Does my own health insurance or boat insurance cover anything while the claim is pending?
Often yes. Medical payments coverage, uninsured and underinsured boater coverage, and health insurance can all come into play. These sources are sometimes overlooked by people handling claims on their own.
How long do I have to file a claim after a boating crash on Geist or Morse?
Most Indiana personal injury claims must be filed within two years of the incident. There are some exceptions, but waiting is risky because evidence disappears and witnesses become harder to find.
