I was having a root through some caravanning forums in which deep discussions about weighbridge accuracy etc were being bandied about and came across this VOSA document that someone had linked to.
I went to have another look today and just get a 404 Page Not Found.
Luckily I had made a copy which is here. http://tinyurl.com/c5a9xy2

It shows that a first time offender under 5% overload will just be ticked off. A first time offender up to 30% overloaded would be issued with a prohinition notice and be ticked off. If you can sort it (re-distributing weight or getting excess weight collected) you can carry on.
No doubt the insurance would be void if a claim were made and they knew you had been weighed and found overloaded by VOSA.

It seems that weighbridges with 50 ton capacity are checked every three months and need to be within 2% accuracy. But the question is - do they check over the whole range? When you check your unbraked trailer to see if it is more than 750Kgs or braked trailer to see if it is over 1800Kgs, or whatever it is rated at, is it as accurate at the low level loading end of the range. The weighbridges mainly use four cells under the platform. Most are 20kg cells, so they only go up in increments of 20kgs. Does that mean if it shows 740Kgs it is less than 740Kg. would adding just 9Kgs then show 760Kgs and look overweight when it is not? Or are they not supposed to click over until you have exceeded the displayed weight.

VOSA's own weighbridges are not available for public use http://www.axtec.co.uk/dynamic.asp , unless they just happen to take you to a Public Weighbridge.


Just for information. I don't claim that any of this will stop you having your collar felt when towing a Folkboat with a Fiesta
 
I agree with what you're getting at, it always amazes and depresses me the things the police get away with, most of them wouldn't know the term ' calibration ' in the true sense if it strolled up and kicked them.

Another scam with towing laws is going by the max on the plate, not the weight being towed which would be far too sensible.

Another example ( not calibration but fudged BS ) is calculating a vehicles' speed by skidmarks; so they take into account the tyre compound, road surface, temperature, vehicle load and humidity do they ? Not when I've seen it done.
 
Got stopped in Dorchester once driving a very overloaded van and told, by the policeman, to follow him to the weighbridge ... it wasn't manned so after about 2 minutes there he asked me 'How many pounds in a kilo ... or is it kilos in the pound?' ...... needless to say I did a 'no idea' routine and got sent away with a warning about overloading vans! (true story!)
 
I think there are far bigger towing crimes committed most days by our friends in the farming community.
Certainly locally, number plates, indicators and general roadworthiness don't seem to be high priorities - it isn't often you seem them being stopped.

I believe the rules are different for them, at least for vehicles / contraptions that do fewer than a certain number of miles on-road per year.

Sorry do nto believe you Dorset police do not let anyone off. It would of been headline news "Man escapes from Dorset without a motoring fine" :D
 
I got my Dehler 22 weighed at a council approved weighbridge. The boat was empty after the winter but still weighed 1460kgs (boat alone supposed to be 950kg). My car has a 1400kg limit!
As lakesailor says I question the accuracy because the weighbridge is for aggregate lorries.
On theVosa site they mention dynamic weighbridges to get axle loads which must also be complied with.
, but I cannot find one.
 
Of course if where you are going from and going to is 75 miles of open road and the nearest weighbridge is over 80 miles away?
If otherwise everything looks ship shape and Bristol fashion?
 
Don't confuse the weight limit of your trailer/van and the maximum towing capacity stared by the manufacturer.

VOSA are looking at plated vehicles, I.e vans and trailers. These will have a plated max load which must not be exceeded.

The towing capacity for your car is a recommendation from the manufactures for safe operation and warranty issues but is not an absolute enforceable limit.

So, if you are towing a trailer weighing 2300kg with a plated max weight if 2500kg with your freelander with a towing capacity of 2000kg it would be in advisable but VOSA would not be interested.

However if you are towing a trailer weighing 2000kg with the same freelander but the trailer only has a plated capacity of 1800kg you are in trouble.

It's plated weights the link referes to, not actually towing weights (technically capacity) as has been suggested

Good luck with that.

For private motorists the police use the stated maximum towing weights the manufacturer has homologated for the vehicle. It will either be on the VIN plate or in your V5 document. The police and VOSA do spot checks targeting caravan and boat outfits. There is plenty of the caravan forums about it.From a caravan forum, Nov 2012
only today i saw a police operation on motor bikes pulling in lorries and transit type vans into the VOSA yard which has a weighbridge . I have often seen caravans and Mh being lead into the yard when they have a caravan /Mh sting .

There is, as suggested in the leaflet, a tendency for them to issue a warning, or a prohibition notice rather than prosecute.

The limit for an old and unplated trailer will be will be decided by the least capable part. The tyres will have a weight limit on them, so 4x that could be the limit. The tow hitch will have a maximum weight on it. The suspension, if of the Indespension type will have a limit. The lowest figure is the one that will apply.

It is no defence at all to say that you don't know. You can tow the trailer to a weighbridge and weigh it on it's own. Subtract that from the vehicle's towing capacity and that is what the boat can weigh.

Where do you live that doesn't have a Public Weighbridge within reach?
 
Interesting about LS's comments that the load cells go up in stages. Back in the 70s, we had to weigh our aircraft from time to time with ref to c. of g. Had a guy come in. He had a suitcase with load cells and resistance measuring kit. Cells were about 3" dia and similar height. I would put them on the jacks and lift the a/craft at three points. He would look at the dials and fill in the paperwork. Asked him one time if he used the same cells for bigger a/c (ours were 6 seat twins or smaller). He used the same kit for B 707s!
