Yes,that's the reason - international standards,it's where we are headed.But usualy a grandfather clause applies - like wooden trailers...4x4 drawbar and all,no way would these things be able to be put on the road now days....but they are out there in use,and legal to boot.The brake hoses complied when first fitted,how come they no longer comply? Double standards,but don't bother talking to LTSA about it...reason is not allowd.
