Mine was on the M25 around by Rickmansworth about 1985 before it was completed, sailing along quite happily with an A framed draw bar fully loaded with very little traffic about, caught up
with an artic eased off slightly as there was a car passing me, waited for the car to pass & I then indicated to pull out checked mirror again as moving out, looked forward and for what seemed like no
reason the car had slammed on its brakes, well I hit the brakes and the rest was an interesting ride as it was going over luckily it stayed upright and some how nothing got hit, the vehicle sorted itself out but
something did not feel right and to be honest I just wanted to stop to calm myself down, I took a walk back and found the A frame of the trailer was badly twisted but had not broken it. not sure if
the car driver was even aware of what had happened.
