Dunno! They have to take into account a 25m strip, maybe a different dude measured it or like you say they’ve done it to try to reduce bridge strikes.
But what I’ve posted is how bridges are to be signed. And yes it is an offence to pass if your vehicle is higher than stated on the sign, it’s irrelevant if you don’t hit it.

The signed height is the max height of a vehicle that can pass, it is not the height of the bridge, so if you’re the same height of the sign, you can go through.Bridges are measured, rounded down to the to 0, 3, 6 or 9 inches in the foot, then have 3 inches deducted and signed at that height.
So it measures, 14’8", round down to 14’6", 3 inches deducted, so it’s signed at 14’3"
So going off this how can they legally mark Beeston bridge at 14’3"
I don’t know that bridge, so you’re gonna have to help me out
This one on the A49 at Tarporley clearly marked at 15’ in the past but now marked at 14’3", nothing has changed apart from the council decided upon this action supposedly due to bridge strikes. I can easily fit under at 14’9" but in theory I’m possibly breaking the law, I think I’d argue that one as it’s now marked up with the wrong height [emoji848]

It got hit agin this week, i think it was thursday, my thoughts about the changed height, maybe, just maybe they lowered the height because if someone misjudges the bend under bridge, their trailer wheels might mount the kerb resulting in a bridge strike for high trailers, it is just a thought but after going under it a few times and occasionally someone comes flying round the bend which is a little bit blind, it makes sense to me.
Who is responsible for setting the height indicator ? The reason I ask is…I drive a lorry with a crane on the back (builders merchant) and the in cab marker is set to 13 ‘10" " . However I have measured to the highest point of the crane from the ground (empty) and it is 12’ .I am reluctant to reset the indicator to the lower setting in case of recriminations from a over zealous h&s obsessed employer .ps I follow the 13’10" measurement, if it takes me longer it takes me longer.
There are 2 bridges next to each other at Greenford, marked up at 15’9", but i have been under with a 16’ decker,
was told by others at that depot that they can get under, so gave it a go, but stopped and went through bl88dy slow with my head out the window,
more room going in than coming out as the road slopes a bit

The driver. In that case it could be someone added a bit to remove the “ah, it’ll probably fit” brigade.
Can’t honestly see the ministry moaning about it being set too high (or at least heing able to issue a fine), but too low and there could and likely be
ruptions. I can’t find the fine for incorrect setting.

Sounds like an attempt to legislate for inept idiots who should not be let anywhere near a truck in the first place.
Nice to see a newbie prioritising on the importance of low bridges btw.
I know our trailers are marked up 3’’ higher to what they are, I also know that on the whole most or maybe all bridges are marked up a couple of inches lower than what they are, so I tend to make my own decisions on whether I attempt one or not…(bring on the shocked self righteous 
, but it’s worked for me so far.)
I’ve often wondered if I was a candidate for getting nicked by some over the top copper if he saw me going under a 15’ bridge with a 15’ trailer, taking into account what I’ve just said.
Either way I’d be crawling under it with suspension down, and my head and shoulders out of window, taking absolutely no notice of any impatient ■■■■ behind me…as I said, it’s worked for me (so far 
) for more years than I care to remember. 
trevHCS:
Isn’t it Scanias which tend to lift the trailer by quite a bit more than others so the “based on 1500mm 5th wheel” thing you get on many trailers is potentially out.
Yes, my midlift puts the 5th wheel at 1300mm instead of the 1250mm marked on most trailers. Always worth remembering that when calculating a height.
The one on the A4034 near Oldbury they have reduced the height .It has been hit by some of our friends who dont read traffic signs

Thankyou. At over a foot above its actual height im pretty confident I won’t hit anything .my concern is , if I alter it (we are regularly asked on the epod do we know what the Indicator is saying,submit a photo) will I be hauled over the coals ■■ This is a company well known for petty beurocrasy dressed up as h&s.

Legally no as long as its legitimate. Internally, probably by sounds of things so I’d leave it.
It could be that they have some units (locally or in company) with a slightly higher crane and there’s some blanket requirement for it to be set like that. I am actually surprised its a changeable type as most rigids I’ve seen just have a fixed one since it can’t alter.
Btw, this is starring to sound like a building company who’s name starts with “J” (if national). In that case I defo wouldn’t change it from what I hear about them. Would take too much explaining to them.

Rich T:
Evening all.
Just a quick question.When you come to a bridge, how much clearance are you happy with?
Reason i ask, i started my new career as a driver 4 weeks ago and admittedly im still relying on my satnav more than i should to get me round the country.
Anyway, end of last week my satnav tried to send me under a bridge with only 2 inches of clearance.
I avoided it and found another way.
What do you experienced drivers consider a safe gap between your truck and any bridge?Cheers
Rich.
If the bridge is 13’ 6" and you’re 13’ 6" you are okay. 13’ 7" NOT okay!!!
the bridge is always 3 inches higher than the height on the sign (hopefully), never hit one using that strategy and worked 40 years on car transporters.
