Why is it important to check trailer lights before a trip?

Checking trailer lights before a trip is crucial primarily to comply with traffic regulations. Proper functioning trailer lights ensure that your vehicle is visible to other drivers, signaling your intentions when stopping, turning, or changing lanes. This is not just a best practice for safety; it is a legal requirement in many jurisdictions. Non-compliance with these regulations can result in citations, fines, or more serious consequences if an accident occurs due to inadequate signaling. Ensuring that your trailer lights are working helps maintain road safety and reduce the risk of collisions, which benefits all road users.
