His tacho will tell us his speed and his lifted axle probably reduced his braking capacity.

If you get any trailer that is loaded in a lop-sided manner weight-wise, then you can easily prise apart the trailer from kingpin-in-jaws when going over anything from an adverse camber to just going around a bumpy roundabout.I’ve got into the habit of pulling a loaded trailer off a bay, going around a corner very slowly, and then straightening up before looking once more underneath to make sure there’s no air between the 5th wheel plate and the underplate of the trailer. Last time I found a big wedge of daylight there (a Sittingbourne job a month back) I straightened up, dropped, and re-hitched the trailer on the straight. The kingpin had been “tipped” out of the jaws partially (enough to worry me about taking it out on the road like that!) by a “puddle” type pothole in the yard the trailer wheels had gone into on one side.
When trailers are parked very close together, I’ll not bother winding up the legs at first - instead, lift the suspension (a bit like the tugs do), pull the trailer out, level it up, THEN engine off, get out, wind up legs, check 5th wheel plate for daylight… If it’s nighttime, I’ll try and pull up somewhere with a decent light source in the background, and use the torch we’re all supposed to carry around with us in this job.
What a load of ■■■■. You’ve been spending too much time in RDC waiting rooms or drive a lot of unroadworthy equipment, one or the other (or both).
Education is also a ‘load of ■■■■’ to people who don’t have any, so I imagine your response to me here comes only from a position of ignorance & inexperience.
Please provide supporting evidence to substantiate your claim that “you can easily prise apart the trailer from kingpin-in-jaws when going over anything from an adverse camber to just going around a bumpy roundabout.”
If that was the case then there’d be hundreds of roll-overs every day given the state of the roads. Until such a time comes where you can back up your claim then I’m afraid you’re talking out of your arse.

I love it when thick ■■■■■■■ post.
I always THOUGHT the same as you (although not stupid enough to quote it as fact), until the experiment was done.
A unit with an empty trailer doing the same speed, first with lift axle down (extra braking wheel - correct?) and second with lift axle up…
Second stops QUICKER than the 1st - this was repeatedly performed at different weights until the lift axle was automatically down and always returns the same results.
The results are available somewhere online but I’ve no idea where. It was down to the extra momentum on the lift axle taking more braking effort than the extra brake discs provided believe it or not.
So, next time you quote something, get it right 
P.S. I’m not always that aggressive but have been after having a pop at Diesel for a while due to some of the crap he posts

. Thanks Wayne, you’ve just made me snort out loud.
TTX boy:
This is trailer obviously was not coupled correctly, trailers do not just un-couple themselves while driving along.
If the trailer was top heavy and it rolled over it would have taken the unit with it.Drivers fault,case closed !
Na total bull . can you see the jaws etc ■■
We had a trailer come off a BIG D fifth wheel the driver had had the same trailer all week.
Came out the yard empty, on a down hill slope turned right onto the main road, through the village then went over /round a roundabout that’s on a twist ( road cambers both ways ) trailer came away from unit.
Police turned out and Mot inspectors were called they (Mot Insp) removed the unit back to our place and removed the 5th wheel for inspection. The Jaws had fallen apart and were missing. the route that the driver was walked by 6 of us looking for any signs of any of the bits from the 5th wheel.( nothing found ) it was decided the failure had occurred at some point and was not driver error.( the truck had been Mot’d the week before.) so you cant say
Drivers fault. case closed
with out the full facts.
From the picture the damage to the back of the unit looks like it jacknifed before trailer and unit parted company.
If it wasn’t coupled properly or (very rare) jaws failed the trailer would just be sat on it’s knees a few yards back having just taken the rear wingtops with it.
My best CSI guess is the load shifted, possibly sidewards and backwards, and the tail wagged the dog and the trailer threw the unit around like a rag doll and eventually came loose.
Think of the chickens.

How do you get all these photos of accidents so soon after they have happened
Because he’s the type of ■■■■■■■■ who gets enjoyment from other drivers misfortune and spends all day Google searching the words ‘lorry accident’.
know that road well and thats a fast corner where he/she has come off
