Brakes: Any combination of vehicles must be equipped with brakes that are adequate to stop within a certain distance. While traveling at a speed of 20 miles per hour without leaving a 12-foot wide lane the combination of vehicles must be able to stop:
Within 25 feet for those vehicle combinations under 8,000 pounds.
Within 35 feet for those vehicle combinations over 8,000 pounds.
Oregon law does not require trailer brakes, but their use is strongly encouraged as an additional safety measure. Oregon law requires that all safety equipment that came from the manufacturer on your vehicle, including brakes, be kept in good working order. So if your trailer is equipped with brakes, they must be kept in good working order.
