When are you required to have brakes on a trailer?

Brakes are typically required on a trailer when it exceeds a certain weight threshold, which varies by jurisdiction but is often around 1,500 to 3,000 pounds. Additionally, if the trailer is designed to carry a specific weight, such as over 3,000 pounds in many states, brakes must be included regardless of the weight of the towing vehicle. It's important to check local laws and regulations to ensure compliance with specific braking requirements for trailers.
