What should a kayaker display to avoid a collision?

A kayaker should display visible lights or reflective gear, especially during low light conditions, to enhance visibility to other watercraft. Additionally, they should use hand signals or whistles to communicate their intentions when navigating near other vessels. Maintaining a safe distance from larger boats and being aware of their surroundings is also crucial to avoid collisions. Lastly, wearing a personal flotation device is essential for safety in case an accident occurs.
