I’ve read this thread and admittedly quickly over some posts but have not/did not come across any mentioning the 5th wheel height of the unit!
It may well be a 4m trailer but that is based on a pre determined 5th wheel height. If that 5th wheel height is higher then the top of the trailer is above 4m.
In that respect Carryfast is right by constantly stating the driver should know the height of his vehicle.

I personally think its ridiculous that we’re still faffing round with feet and inches anyway. Metric makes far more sense. Will annoy certain little Englanders I know but there we go.
+1. We moved on when I was a kid just like decimal currency.
Er yes, and it was only my second post on here, bit nervous now 
But back to the bridge, if I have a chance, as it’s quite local to us, I will go and check it if I can when I have a spare few minutes. With a tape that is, not our 4.1m trailer 
I will do it in metric and imperial as I am completely bilingual.
This is another local bridge with a slightly different interpretation
That still gets hit regularly by all sorts of things though.

Yes, the strange thing is this is the second time in a few months. There was a big fuss last time about what appears to be an error in the signage but nothing has changed. Our yard is only 5 minutes away and we have a 4.1m trailer but I am not keen on the experiment, we go around the other wayHere is the last time

The train must have pushed it down! Simples
But did they push in down in Imperial or Metric?
790 mm. 
and it was old on springs too. stamped up with SNCF. FROGS FAULT. 
I have never had a 4m trailer that has actually come under 4m even on an 1100 5th wheel scmidts are usuall built to 4.04 based on an 1100 5th wheel

And I have big news for all you metric devotees - brexit means brexit so you’re all going to have to forget this foreign metric rubbish and learn to measure and weigh stuff properly.Does it also mean the UK will be back to £/s/d? How much was a guinea now? 21 shillings wasnt it?
hope so - far more interesting.
Will that also mean going back to 6/8d an hour and ten bob a night out?
Glen A9:
Carryfast is of course right, because it is entirely logical in the 21st century to give precedence to a system of measurements based on the size of a barley corn.
Thank you for this video, I can not stop laughing
While we are on the subject 
, why people mention fuel being measured in imperial gallons, when in fact I never see gallons in UK, not on the fuel station, there everything is in liters. Milk bottles are not in gallons either.
Yet when I read car reviews regarding car fuel consumption it states MPG, what the hell, at the petrol station the display is in liters, why fuel consumption is not given in liter like in Europe, or lets change the petrol station numeracy back to gallons.
In US fuel is in gallons at the pump, milk has 2 main sizes 1 gallon and 1/2 gallon, of course American gallons. But my point is, why we talk about imperial(UK) gallon when there is nowhere to be found?
CF you are very thick headed man, saying imperial measuring system is superior in 21 century is a complete farce.
P.S. If its up to me I’ll standard all measurements in the whole Europe if not the World. Every time when Im in another country Ive to learn new clothing size, new shoe size, new this/that size, freaking time consuming and unnecessary. Even American and British shoe size, clothing size and gallons are different 
Oh yeah and the fuel octane level as well.
Oh yeah can we change this PSI ■■■■ as well, is so much easier with bar. 15 inch tyre 2.2 bar, 16-17 inch tyre 2.4 bar etc.
It’s because of the right mish mash of measurements we use in the UK. It was official policy to convert fully to metric, but subsequent governments have given up and left the job unfinished.
So we have fuel being sold in litres, but distances and speeds on road signs being in miles/mph and hence odometers in cars being in miles. Miles per gallon doesn’t make sense because we don’t buy fuel in gallons and l/100km (the official measurement) doesn’t make much more sense since drivers aren’t familiar with distances in km.

I mentioned fifth wheel height page 5…

and in 1960 that 6/8d would have bought you 5 pints of beer. how many pints does an hour of lorry driving buy you now?
It is all the fault of Maggie Thatcher, A frame trailers and Jeremy Clarkson .
Not sure how Napoleon is to blame.
Why has CF not mentioned Tony Blair and Michelle Le Pen yet ?
I got my Allegro under that bridge, with a roof rack on and five mountain bikes, so what is the problem ?
And I was towing a year old trailer .

No thanks you can shove your Newton Metres and litres/100 km’s and since when did the Americans sell milk in gallons and half gallons rather than quarts ( around a litre ) or bar was a metric measurement rather than kg/cm2.On that note exactly how heavy is the bs Newton as a measure of torque when applied to a lever and as we all know a bar is one atmosphere which is 14.5 psi.
Meanwhile maybe now we know why the Americans chucked you out because you refused to recognise bridge heights in feet and inches.

I dunno about you folks, but I’d never even consider taking a C+E under a bridge marked as “only” 13’, any more than I’d risk it with the Blackwall Tunnel, also that same marked height.If you have not measured the height yourself in person, I have taken as a rule of thumb “Always assume your combination is at least 13’9”.
If your cab marker says 13’0" for instance, and you hit a 13’8" bridge - who’s fault is it?
Yours, because you were driving.
The point I’m making is that there cannot surely be many artic combinations around (box or curtain) that have heights much UNDER 13’9" surely?
What about almost every fridge trailer on the road?
They’ve all been 13’9" or more down here in my experience, including all the ones I’ve driven in the past 5 years on agency… Maybe some of these northern backwater ones have heights lower… I wouldn’t know about them though.
I did drive a 13’4" years ago that was a metal corragated box trailer - but that had no fridge on it.

If we’re going to refer to closed minded ignorance I’d suggest that fits the definition of those who can only get their heads around the metric system to the exclusion of all alternatives.On that note I was taught to use both systems by necessity and without prejudice and personally came down in favour of imperial.On that note I think we’re actually dealing with closed minded ignorant Europeans and Europhiles not little Englanders.Which in this case means drivers knowing the height of their vehicle in feet and inches.
While decimalisation of the currency has nothing to do with exclusive recognition of the bs metre as the only relevant measure of distance.Nor the litre or gramme regards liquid or weight.

Oh no now you’ve done it you’ve used feet and inches and the metric nazis will hunt you down.

newton is a force not a weight - so very relevant for space travel
