ive just found out that if i tow a trailer or caravan i can get nicked !
why? i passed my car test after 1/1/97 where the law once again changed (check dvla website)
you need to take a test which is dearer than the bike test doh ! (the reason i got a trailer was so i didnt have to do my bike test and just have fun riding offroad!)
SOLUTION; buy a bike rack ! its a lot easier to reverse as well
hope this helps!
