Interesting amount of regulation on trailers over there. Here the law is fairly cloudy and sparse. No registration or testing of trailers, and fairly low enforcement of trailer license law. It drives me mad, as both my trailers are big (12ft &16ft) and always maintained. But.. Drive over here for a few hours and you'd see all sorts, today a 1995 Toyta Carina with a 3 axle cattle trailer, with no lights... Madness
