Perävaunujärjestelmä

Perävaunujärjestelmä refers to the braking and lighting systems of a trailer, designed to ensure safe towing and compliance with road regulations. In Finland and many other European countries, trailers exceeding a certain weight or speed capability are required to have a functional braking system. This system can be passive, meaning it activates when the towing vehicle decelerates, or active, which is a more complex system often controlled electronically.

The lighting system is equally crucial and typically includes brake lights, indicator lights, tail lights, and a license plate light. These lights must be synchronized with the towing vehicle's lights to clearly signal the trailer's movements and presence to other road users. Power for both braking and lighting is usually supplied through a dedicated cable and socket connection between the towing vehicle and the trailer.

Regular maintenance and inspection of the perävaunujärjestelmä are essential for safety. This includes checking brake fluid levels, ensuring all lights are operational, and verifying the integrity of the electrical connections. Malfunctioning braking or lighting systems can lead to dangerous situations and result in fines if detected during traffic inspections. The specific requirements for perävaunujärjestelmä can vary slightly based on trailer type and size, but the fundamental principles of safe braking and visibility remain constant.
