Which equipment is legally required to be present on a boat trailer?

In Illinois, it is legally required for boat trailers to have lights. This regulation ensures visibility and safety while the trailer is on the road, especially during dusk or at night. Proper lighting, which includes brake lights, turn signals, and tail lights, allows other drivers to see the trailer and understand its movements, significantly reducing the risk of accidents.

While other equipment like reflectors, brakes, and tires are indeed important for the safe operation of a trailer, the specific requirement for lighting is crucial for compliance with road safety laws. Therefore, having lights is a fundamental requirement that must be adhered to for legal operation on public roads.
