Indiana Boat Light Laws: Essential Rules & Regulations

By Sarah BrownNovember 28, 2025

Navigating Indiana's waterways at night can be a beautiful and peaceful experience, but it's crucial to ensure your boat is equipped with the right lights to keep you safe and comply with Indiana boat light laws. As a responsible boater, understanding these regulations is key to preventing accidents and ensuring a smooth boating experience for everyone. Let's dive into the essential aspects of Indiana's boat light laws.

Indiana boat light laws are designed to improve boater visibility and communication, making it easier to navigate at night and avoid collisions. The Indiana Department of Natural Resources (DNR) divides boating periods into three categories: daytime, twilight, and nighttime, each with its unique lighting requirements. Let's explore the key lighting rules for each of these periods.

Daytime Lighting Requirements

During daylight hours, the lighting requirements for boats in Indiana are minimal. However, it's essential to have a few key safety items on board to ensure you can signal distress if necessary.

Boat operators must carry on board a sound-signaling device, such as a whistle or foghorn, and a visual distress signal, like flares or an electronic visual distress signal (eVDSS). While not specifically classified as daytime lighting, these safety devices are crucial for daytime emergencies and should always be accessible.

Sound-signaling Devices

A sound-signaling device is a must on Indiana waterways during the day, enabling boaters to alert others to their presence and signal for help when needed. The DNR recommends carrying a whistle (or other audible signaling device) onboard, as it's lightweight, durable, and easy to use.

Visual Distress Signals

Visual distress signals help other boaters and rescue personnel locate you in an emergency during daylight hours. Flares are a popular choice, while eVDSS provides a more environmentally friendly alternative. Always store these items in a dry, accessible location on your boat.

Twilight and Nighttime Lighting Requirements

As the sun begins to set, Indiana's boat light laws demand that operators display appropriate navigation lights to ensure visibility and prevent collisions. Be sure to have the correct lights installed and turn them on as required.

The International Association of Marine Aiding Organizations (IALA) rules govern Indiana's nighttime navigation lights. These rules apply to all boats less than 39.4 feet (12.0 meters) in length on Indiana waterways, regardless of whether the boat is being towed or propelled.

Under 26 Feet (7.9 Meters)

For boats up to 26 feet in length, navigation lights consist of a combination of red and green side lights and a white stern (rear) light. The red and green side lights must be visible to other boaters from a distance of at least one mile and can be grouped together or placed side by side.

26 to 39.4 Feet (7.9 to 12.0 Meters)

Boats ranging from 26 to 39.4 feet in length must display additional lights. In addition to the red and green side lights and white stern light, these vessels must also have a masthead light – a white light visible from a distance of at least two miles. Furthermore, these boats may need to display a second masthead light or a stern light above the white stern light if they exceed a certain length.

Sailboats

Sailboats of any length must display sidelights and a stern light. If the sailboat is being towed, it should display a masthead light as well. For sailboats over 39.4 feet in length, additional lights may be required.

Power-Driven Vessels Over 39.4 Feet (12.0 Meters)

Boats longer than 39.4 feet are generally required to display lights equivalent to those displayed on ships under the IALA rules. This includes multiple masthead lights, range lights, and stern lights. Always consult the most current regulations for these larger vessels.

As you prepare for your next nighttime boating adventure in Indiana, make sure your vessel is equipped with the appropriate lights for your boat size. Familiarize yourself with Indiana's boat light laws and always prioritize safety on Indiana's waterways. Get out there, enjoy the peaceful solitude of Indiana's lakes and rivers, and navigate with confidence knowing that you're well-equipped and prepared. Happy boating!
