According to UK regulations every bridge must be atleast 3 inches higher than maked therefore a 14’6" bridge must have atleast 14’9" clearance.Have you got a link to this ‘UK Regulation’ or did you just pull that particular bit of BS from your ■■■?
I don’t know about it being a ‘regulation’ but it is a guideline for those involved in measuring bridge heights.
Yeah, I know but a guideline is not a regulation as claimed by PH.

Remember it depends on the sign. A circular sign will specify the maximum height of a vehicle allowed to proceed and will not necessarily be the height of the bridge above the road surface.
14 foot on a round sign and driving a 14 foot high vehicle you can proceed and will pass under the bridge.
14 foot on a triangular sign and driving a 14 foot vehicle and you are likely to scrape the roof of the trailer as in that case the 14 foot refers to the maximum headroom.
Can you give the source of this information?
It differs from what I’ve ever read, which is:
Circular signs are mandatory, vehicles higher than the shown height must NOT pass under.
Triangular signs are warning signs…
That’s exactly what I said.
Circular sign with 14 foot marked on it means a 14’ vehicle can proceed, a 14’ 1" vehicle cannot. Doesn’t matter if the actual structure is higher than the figure on the round sign, and it will be, unless your vehicle height is equal to or lower than the figure displayed you cannot pass the sign.
Triangular sign warns of the maximum headroom ahead, so 14’ on the sign and driving a 14’ vehicle you are likely to make slight contact.
The round signs don’t tell you the actual height of the bridge, and the clearance will be higher than the figure on the sign, The triangular ones tell you that clearance.
I doubt that a 14 foot high vehicle willl scrape a 14 foot high signed bridge…examples please!
As the triangular sign is telling you the headroom is 14’ and if the vehicle is 14’ then there is a good chance you could make slight contact whereas with a round sign in that situation you won’t as the headroom will be more than that signed.

How is that BS? The only BS here seems to be your understanding of road signs, triangular and round signs are not giving you the same information.
The triangular sign is telling you the headroom ahead, the distance between the road surface and the structure, and if it is saying 14’ and you are driving a 14’ vehicle the headroom and the vehicle are the same and if they are the same then the vehicle will just scrape, literally, through. Of course there is a good chance the headroom will be a little more than 14’ but no guarantee.
With a round sign telling you the maximum height of a vehicle allowed to proceed then the headroom ahead is obviously more than that figure because they don’t want you making contact of any kind.
One sign gives the height of the bridge, the other doesn’t. Let’s hope it’s single deckers you drive eh?
This bus is just about to pass a red triangle signed at 12’3"
look here
The bigger problem is the width, the buses only have about an inch either side of the folded mirrors

Give me examples where you know that the sign saying the same as your vehicle height will result in just scraping through! There are many where it is well known that higher vehicles can easily pass through.
Thats the BS.
I drive all sorts of vehicles and some very high. I understand fully what the signs mean. I have never yet come across a warning or mandatory sign on a bridge which would not allow a vehicle of that height to safely pass under.
As has already been said on this topic…there are safety margins built in.
Some low bridges you could get a high roof van stuck under, so vehicles don’t have to be tall to have problems.

Yes there are many where a higher vehicle can pass through, and certainly with the round signs as the headroom will always be more than the figure on the sign.
However, the triangular sign tells you the headroom and there may or may not be a safety margin built in, and you cannot assume there is. So, if there isn’t then with a vehicle the same height as that marked on the triangular sign and the height on the sign being accurate due to no margin then it will scrape. That’s not BS, that’s just simple maths.
You seem to be treating all signs as the same but they are not.

No idea if it is in the Highway Code, I just know that is the limit for sign-age. Or at least it usually is, I’ve seen things marked higher than that.Every bridge in Spain has its height marked, even if it is 200m in height.
Might be a warning for pilots looking for somewhere to land during one of the air traffic controllers many strikes!! Eh Harry! 
As for the OP!! Drivers fault all the way!! Unless the road surface has recently been renewed like what happened in Edmonton Green a few years back when a double-deck bus ■■■■■■■ the bridge! The road had to be redone under the bridge!

Your theory is still of the MMTM kind…
Give me some examples where a vehicle of the same height as the warning sign on a bridge has hit or scraped the bridge…The margin is there to avoid this kind of thing.
I have no problem at all taking a vehicle under a warning triangular sign which is the same height as that marked on the bridge. The sign is the maximum safe clearance.
Wheres your problem with this?! 
It doesn’t really matter if the sign is the same as the available height, if the bridge says 14’ and the trailer measures 14’ and 1/2 an inch, you cannot pass the round “order” sign, regardless of extra clearance.
The triangular sign is “warning” that you have to be careful.
It is the difference between a Stop and a Give Way Sign.

Bridge Strike! Whose Fault?It can only ever be the drivers fault, especially if he doesn’t have a clue how high it is or how to measure it.
You only need a sweeping brush and a tape measure to set your height marker exactly. That way if you hit a bridge, you can ring the owner
OK WN I do carry measure tape with me but how should I carry with me a sweeping brush everyday if I do not have my own unit

Don’t you sweep any trailers out? I still have a brush in the boot of my car from 2009
You can still use a measuring tape to measure a trailer, the brush just makes it easier when it is windy

I’ve had my brush for nearly 15 years, course it’s had a few new handles and a couple of new heads.
I went under one in Newport which measured the same as the truck no probs when I turned around and came back it was marked lower, , went back under it on the wrong side of the road.
In Kings Lynn the Southgate is marked at 13ft 9 however due to its shape we used to pass under at 16ft although it was then marked at 15ft 9. When it was remarked I rang the police to ask what I should do as every other route into Kings Lynn has a weight limit, police said just drive around the south gate instead.

I watched my tm measure my trailer load of roof trusses once, 15’9 he said. When I got to delivery site I found I had shaved off the top corners and slacken all my straps on a bridge with no height marking, minimum 16ft I thought these have to be?Generally 16’ 6" before signs are needed.
That’s a highway code rule isn’t it Neil? Good to know when you are on your test.
No idea if it is in the Highway Code, I just know that is the limit for sign-age. Or at least it usually is, I’ve seen things marked higher than that.
it would be nice if they warned you before committing to the road that leads to it. how many of them have no warnings until a couple of hundred yards short of the low bridge? some of them warn you at the junction even if its a mile or 2 along the road, others dont warn you until you can see the ■■■■ thing
Our ‘standard’ trailers are 15’6" high and I have noticed in my work that most low bridges on A Roads do have adequate prior warning signs.
There is normally even warning signs at the last available alternative route (possibly the one and only benifit of our H&S mad culture).
Even the low bridge on the NCR at Bounds Green has a warning sign at the last alternative route. Unfortunatly that’s at Brent Cross Haha.
As always, I’m happy to be proved wrong…

Just before that bridge at Bounds Green turn left and go up and along by Arnos Grove station to get back to the NCR. Takes an extra 2 mins. OK to use outside Lorry Ban times.

Do you think it’s not signposted to discourage diverters? Or have I missed the sign in the past?

I think your first guess is correct. There is no ‘alternative route’ sign (or hasn’t been in the past; a good year since I last used it with a 16’)
