If any body with a that owns a boat with a trailer driving on a road should have a brake tag. If you would have an accident, or involved in an accident pulling a trailer, not just a boat trailer, any trailer and have no inspection tag for that trailer is in for trouble. If the government would use the money for boat trailers inspection or fines collected put in real good use, like fixing public boat launch fixing public parking lots. I believe anybody wouldn't mind giving their 10 bucks for an inspection. BUT WE LIVE IN LA. My two cents again
