Jet Ski Laws in Indiana (2026): Rules Every Rider Must Know

Most people just hop on a jet ski and go. They don’t think about the law. But in Indiana, the rules for riding a personal watercraft (PWC) are strict. Getting caught breaking them can ruin your whole day on the water.

Honestly, a lot of riders don’t know half of these rules. Let’s fix that right now.

What Is a Personal Watercraft (PWC)?

A personal watercraft, or PWC, is a small, motorized water vehicle. Jet skis, Wave Runners, and Sea-Doos all fall into this category. Indiana law treats them like motorboats. That means all boating laws apply to them.

Right, so it’s not just a toy. It’s a motor vehicle under Indiana law.

Age Requirements for Riding a Jet Ski in Indiana

Here’s where things get serious. Indiana has strict age rules. You need to know them before anyone gets on the water.

Under 15 Years Old

No one under the age of 15 can legally operate a jet ski or PWC in Indiana. This applies to all PWCs with more than 10 horsepower. That’s basically every jet ski you’ll find on the water.

Period. End of discussion. No exceptions.

Ages 15, 16, and 17

Wondering if teens can ride? Yes, but only with the right steps. A rider who is 15 or older but doesn’t have a valid driver’s license must complete an approved boater education course. They also need to carry an ID card issued by the Indiana Bureau of Motor Vehicles (BMV) while on the water.

If the teen has a valid Indiana driver’s license, they can ride without the safety course requirement. But the license must be a real Indiana driver’s license, not from another state.

18 and Older

Adults with a valid driver’s license can operate a jet ski on Indiana’s public waters. If you’ve never had a driver’s license, you still need to complete a DNR-approved boater education course and carry your Indiana BMV ID card with you.

Pretty straightforward, right?

Boater Education Card

Let’s talk about the Boater Education Card. Think of it like a driver’s license, but for the water.

If you’re required to take the boater safety course, you need to carry your card on the water at all times. Law enforcement officers can ask to see it. If you can’t produce it, you can face a fine.

You can complete the course online through the Indiana Department of Natural Resources (DNR). Once you pass, you get your card. Keep it with you every single time you ride.

Jet Ski Registration in Indiana

Okay, this one’s important. Your jet ski must be registered with the state. All motorized watercraft in Indiana need to be registered and numbered. This rule has no wiggle room.

Once you register, you’ll get a registration number and two decals. The number must be displayed on both sides of the bow (front) of your PWC. The letters must be at least 3 inches tall and in plain block characters. The color must contrast clearly with the hull color.

The decals go to the right of your registration number, within 3 inches of it.

You must also carry your registration certificate on board whenever you’re riding. Not in your car at the boat ramp. On the jet ski with you.

Life Jacket (PFD) Rules

This is probably the most important rule on this list. Every single person on a jet ski must wear a life jacket. No exceptions.

The life jacket must be approved by the U.S. Coast Guard. It must be a Type I, II, or III PFD. Type V PFDs are not approved for jet ski use. A ski belt is not an approved life jacket.

Stay with me here. This includes the operator, all passengers, and anyone being towed. Everyone. No one gets on without one.

Children under 13 must wear their PFD at all times while on the water. Even on a larger boat, a child under 13 must wear one unless they’re below deck or the boat is docked.

The Kill Switch Lanyard

Here’s one most people forget. Your jet ski comes with a safety ignition switch and a lanyard. The lanyard attaches the switch to you. If you fall off, the engine cuts out automatically.

Indiana law requires this lanyard to be attached to the operator at all times while riding. The safety switch must be fully functional. Don’t remove it or disable it.

This rule exists for a very good reason. A riderless jet ski can seriously injure someone. Think of it like a seatbelt. You just put it on.

When Can You Ride a Jet Ski in Indiana?

Jet skis can only be operated during daylight hours in Indiana. That means from sunrise to sunset.

It is illegal to operate a PWC between sunset and sunrise. The only exception is if your PWC is equipped with proper navigation lights. But honestly, most standard jet skis are not set up for night riding.

This also means no water skiing or tubing after sunset. Those activities require speeds over 10 mph. That’s not allowed once the sun goes down.

Speed Rules on Indiana Waters

Speed limits on Indiana waterways are serious business. Here are the rules every rider needs to know.

Between sunset and sunrise, no one may operate any boat at more than 10 mph. This applies even if you have lights. Jet skis should simply not be ridden at night.

During the day, you must always operate at a “reasonable and prudent” speed for the conditions. That means slowing down in congested areas, near swimmers, near docks, and near other vessels.

Obey all posted regulatory markers on the water. If a buoy says “Idle Speed” or “No Wake,” that means you slow way down. You don’t try to squeeze past the marker at full throttle.

Distance Rules for Jet Skis

Indiana has specific distance rules for PWCs. These exist to protect swimmers and other boaters.

PWCs must maintain at least 200 feet from the shoreline unless traveling at idle speed or coming in to dock. You may not come within 100 feet of another PWC or within 50 feet of another vessel or person in the water unless you’re at idle speed.

If you’re within 150 feet of a diver-down flag, you must slow way down. Divers are in the water there. That’s not the place to be showing off.

Boating Under the Influence (BUI)

Most people know about drinking and driving. Fewer people realize that boating under the influence is just as serious. Personally, I think this is the rule most people underestimate.

In Indiana, you are legally under the influence on the water if your blood alcohol concentration (BAC) is 0.08% or higher. You can also be stopped and arrested if your BAC is above 0.05% and your ability to operate the watercraft is impaired.

This applies to jet skis, boats, kayaks, and any other watercraft. All of them.

BUI Penalties

Here’s what you could face if you get caught.

A first offense is a Class C Misdemeanor. You could lose your operating privileges for 90 days to 2 years. That includes both your boat operating privileges and your driver’s license.

A second offense within five years gets more serious. You could face jail time, larger fines, and lose your operating privileges for up to 2 years.

Third and subsequent offenses result in even harsher penalties. The law gets stricter each time.

By the way, if an officer asks you to take a breath test and you refuse, you automatically lose your operating privileges for one year. You can’t just say no and walk away.

Towing Rules for Jet Skis

Can you tow someone on a tube or water skis behind a jet ski? Yes, but only under specific conditions.

The jet ski must be designed to carry at least three people. There must be a rider on the PWC besides the operator. That person acts as a lookout. Their job is to watch the person being towed at all times.

Towing is only permitted from sunrise to sunset. No towing after dark. The rope used for towing cannot be longer than 75 feet.

Also, no one may operate a motorboat or PWC to tow a skier if the operator is under 14 years old.

What You Cannot Do on a Jet Ski

Okay, pause. Read this carefully. These behaviors are illegal in Indiana.

You cannot ride facing backward on a jet ski. You cannot carry more passengers than the manufacturer’s recommended capacity. You cannot remove or tamper with any backfire flame arrestor or ventilator installed by the manufacturer.

Reckless operation is a crime. Reckless operation means operating carelessly with no regard for the safety of others. Excessive speed in congested areas, wake jumping near other vessels, and similar stunts can get you charged with a crime.

Accident Reporting Requirements

If you’re involved in a boating accident, you may be required to file a report. You must file an accident report with the Indiana DNR if the accident results in injury, death, disappearance of a person, or property damage over a certain amount.

You must file the report within 24 hours of the accident. If you fail to report, you can face a Class A Misdemeanor. That’s more serious than most people realize.

Don’t walk away from an accident without knowing your legal obligations.

Special Rules for Certain Areas

Not all water in Indiana has the same rules. Some lakes and waterways have local restrictions.

Jet skis are completely prohibited at Indiana Dunes National Park. This includes all waters and beaches within the park. Don’t try to ride there. Rangers will stop you.

Many lakes in Indiana have their own speed limits, use restrictions, and designated areas. Always check local rules before riding on a new lake. The Indiana DNR website has resources to help you find this information.

How to Stay Legal and Safe in Indiana

You’re not alone if this list feels like a lot. Most riders don’t know all these rules when they first get started. Don’t worry. Here’s a quick breakdown of what you need to do.

Register your jet ski at the Indiana BMV before hitting the water. If you don’t have a driver’s license, complete the DNR-approved boater safety course and get your card. Make sure every rider has a Coast Guard-approved life jacket. Attach the kill switch lanyard before every ride. Stay sober. Ride only during daylight hours. Know the speed and distance rules for wherever you’re riding.

That’s it. Pretty simple when you break it down like that.
