Whats the law on trailer brakes? are they required on all twin axle trailers, horse boxes etc?

To my knowledge (not necessarily correct) anything above 750 kg gross weight has to have brakes, regardles of the number of axles.

I would presume that would cover an average size car on a transporter trailer,

Indeed it would.
Average car on trailer would be around 1.5 tons. Towing that withour brakes on the trailer is a bit lethal.

Brakes are required if the trailer is over 750kg or if the trailer weight more than 75% of the towing vehicle hope that helps

750kg or half the laden weight of the towing vehicle.

But what is the max weight that can be towed if the trailer is braked?

I'd imagine that's governed by the car doing the towing?

If the trailer is over 750kg (e.g. laden carporter) it needs both brakes and an EB driving license (assuming towing vehicle is a car) for the operator. Otherwise its the same as driving without a valid legal license, which is Most Very Ungood :eek:

Weight of trailer for EB is a real gray area; I've never seen a hard-and-fast limit myself. Even a heavy-duty diesel isn't going to be able to pull anything close to EC1 levels (which has a max of 12000kg, and other conditions) so its probably just like Anan1 said

Thanks Guys,

I found this since. It says that the towed weight (braked) must not exceed the weight of the car itself.:)

"To tow a caravan/trailer the weight of any caravan/trailer equipped with over-run brakes must not exceed maximum weight of towing vehicle"

This always causes confusion, you can tow a trailer >750 kg d.g.v.w (design gross vehicle weight) with a B licence if the d.g.v.w of the combination is <3500 kg and the d.g.v.w of the trailer is less than the unladen weight of the towing vehicle.

If the trailer d.g.v.w is <750 kg, a driver with a B licence can drive a combination of up to 4250 d.g.v.w once the towing vehicle is in Category B.

Whats the law requiring an independent brake on a trailer?
