Do You Need a Trailer Brake Controller?

How to decide whether your tow vehicle needs a brake controller for campers, enclosed trailers, boats, and utility trailers.

A trailer brake controller sends braking power from the tow vehicle to trailers with electric brakes. It can make towing safer and more controlled when trailer weight increases.

You likely need one when:

• The trailer has electric brakes.
• You are towing a camper, enclosed trailer, equipment trailer, or larger boat trailer.
• Your state or local rules require trailer brakes above a certain weight.
• The vehicle owner’s manual or trailer manufacturer requires trailer brake control.

You may not need one when:

• You are towing a small utility trailer without brakes.
• The trailer uses surge brakes rather than electric brakes.
• The total loaded trailer weight is light and within the vehicle’s published limits.
