Red Seal Transport Trailer Technician Practice Exam

What are the legal requirements for trailer lighting?

1. Trailers must have functional headlights

2. Trailers must have functional brake lights and turn signals

3. Trailers must have decorative lights

4. Trailers are not required to have any lights

The correct answer is: Trailers must have functional brake lights and turn signals

Trailers are required to have functional brake lights and turn signals as a fundamental safety measure. These lighting elements are crucial for signaling the driver’s intentions to other road users, enabling safe communication when the trailer is slowing down, stopping, or changing direction. Compliance with these requirements helps to prevent accidents and ensures that the trailer can be safely towed on public roads. In contrast, while functional headlights are indeed important for a vehicle's operation, trailers do not typically need them, as they are not designed to drive independently. Decorative lights, while they may enhance the visual appeal of a trailer, do not meet essential safety standards and are not legally required. The absence of lighting on trailers is inadequate for road safety; therefore, trailers must adhere to regulations that mandate the presence and functionality of specific safety lighting, particularly brake lights and turn signals.
