The DOT requires manufacturers to equip any trailers over 3,000# GVWR with brakes.If your trailer has brakes, your vehicle needs to have a brake controller to actuate the trailer brakes.Some newer model vehicles are equipped with OEM brake controllers from the factory. If your vehicle does not have a factory trailer brake controller, we carry a variety of options in stock and our shop technicians install them routinely. Your salesperson can assist you in verifying if you need to have a brake controller installed, and availability and pricing for installation on your particular vehicle.Trailers with brakes can be pulled without a brake controller because the brakes will just freewheel without a controller to actuate them, HOWEVER,  DOING SO WILL INCREASE YOUR RISK OF AN ACCIDENT AND ACCOMPANYING LIABILITY.
