I agree in principle with Camel, but but as Clive has pointed out, there considerable challenges to getting a workable system. It would need each trailer to be registered and to carry a visible unique identifier, that would require central Government to set up the services, or at least extend the remit of the DSA or DVLA. In some EU countries this is already the case.

Trailer MOTs would have to be carried out at regulated sites. This could be existing MOT stations, or perhaps at trailer specialists such as caravan service centres. It's important to note that the MOT would only look at the trailers running gear, and general body work, not at habitation or other specifics such as gas electrics water etc. Simple allowing it to be assessed by a service technician with unknown training or ability is not a good way if you are looking for confirmed performance.

You can bet there's some be a charge for this.

Would this prevent RTIs? - no. Would it stop badly matched outfits? - no. Because those are basically down to driver decisions and experience.

As for road fund tax, I am a long term believer that it should be loaded onto fuel, rather than a separate inequitable system we have at the moment. By loading fuel, those who wear out our roads the most by shear distance or by the weight, will pay a fairer share of the tax burden. it's virtually impossible to avoid paying, even for overseas visitors. Oh and before the HGV lobby start to shout "unfair" most of the wear on our roads is due to the weight of vehicles such as HGV's moving the surface, causing cracks that allows water in and frost does the rest to detach the surface allowing it break up.

However, the transport landscape is changing, electric vehicles, so as their proportion increases as it will, there will have to be some means of collecting revenue from them, so we're likely to see annual RFT remain.

But the issue of MOTs is completely different to that of overloading. Assuming that there were such a thing as an MOT on caravans in the UK, a caravan is unlikely to be submitted to an MOT in a laden condition, so the way it is loaded, or even overloaded, would never be reflected in such a test.

However, the visible unique identifier of a caravan that would be necessary for an MOT, already exists. It is the VIN which every caravan, at least those built since the introduction of whole vehicle type approval, carries on its statutory plate.

Lutz, i'm making two points one mot's and the other a clarification of identifiing the gross , tare and payload of a caravan and put in one place on the caravan regardless of make inside a locker so we all know where to look for the information.

Despite investigating accidents for many years I have not seen an accident that may have been caused by a defective caravan, in general those running near or over the 100% figure appear most frequently. There must be the odd one caused by defective caravans but they are so minor that the cost of MOT's or similar is not in my view justified.

That's exactly the conclusion that the investigations involving UK authorities and EU ones came too. The cost benefits were not any way near positive. One conclusion being that if countries wished to introduce such schemes as registration and/or testing they would be introduced as domestic legislation.

But the weight plates are not in the same location on cars, either. Some have the plate on the front upper crossmember, others on the front bulkhead, others again on the B-pillar. There is no requirement to plate the tare or payload. There is little point in plating ex-works tare anyway because more often than not, and especially with caravans, further permanent fittings, such as batteries, motor movers, etc., are added before it is delivered to the customer, so an ex-works figure is not particularly useful. Plating tare would also mean that every caravan would have to be weighed in the factory before the plate can be made.

On the subject of MOT, when a vehicle(or trailer/caravan)is tested its tested as presented and only in the garage space.I say this as an mot on a trailer would be pointless.I'll give you an example.vehicle comes in for test,I fail it for bald tyres and wiper blades non existent,fail and put back outside on yard.customer comers with another vehicle,same,swaps wheels and blades.I drive back into garage,mot pass,drive back outside.Customer then swaps all parts back to original vehicle.
So having a statatury mot would be pointless.
P.s this was on an ice cream van.

On that basis any MOT on any vehicle is pointless.
However, there are items that are safety related and which are not so easily replaced after the vehicle has been successfully submitted for an MOT. One is structural corrosion and another braking performance. There are undoubtedly a not insignificant number of caravans that have never been serviced since they were delivered to the customer and have spent many years slowly rotting away between infrequent use.

My example was just to highlight that people like you and me,law abiding citizens who take pride in our vehicles and like to put our and others safety at the front of all things would respect the system,others who do not care about you or I will always get around any testing system.
Tyres and brakes are the most important,galvanised chassis will very rarely cause any roadworthy issues.

Don't you believe it. I have seen even galvanised chassis frames that have rotted right through and the axle to come adrift as a result. I would therefore expect corrosion in general, also of the hitch itself, to be a major factor if caravans were subjected to an MOT.

The discussion on caravan MoTs is a diversion from the more serious issue of those who drive without licence, insurance, MoT and possibly under the influence of drink and/or drugs. Hit these areas and you really begin to reap a benefit without the negativity of introducing more bureaucracy.

So after getting mine back and looking round I've noticed numbers are different compared to outside compared to the gas locker , top is front locker , lower one is beside entrance door .

That doesn't surprise me but the details shown in the lower picture don't comply with the regulations. The type approval number and the maximum permissible axle loads and noseweight are missing and details that are not legally required (model designation, MIRO, tyre size, tyre pressure, wheel torque) aren't clearly separated from those that are required.

The lower picture information label is pretty standard for UK manufactured caravans. Give its couple of years and Craig's enthusiastic washing and it will be illegible anyway. I note the difference in maximum weight between the door label and the label in the locker. Little wonder that some get confused

I have a similar but slightly different question. Again an Elddis van. Door sticker says -
MIRO 1132 KG
MTPLM 1310 KG
Tyresize 185 R14 102
Tyre pressure 57 psi

and gas cupboard sticker says -
1310 KG
0- 100 KG
1- 1500 KG
2- N/A KG

Door sticker is almost illegible and likely to fall off next time it's washed so would this suggest that in reality I have a safe MTPLM of 1500 and that 1310 is "just" a marketing number kept low for people who need a low number?
If I could work out how to attach pictures I'd do so if it helped....

Your door and locker sticker plates both show MTPLM of 1310kg which is set by the caravan maker who are the Design Authority for the caravan. The 1500kg is your axle load set by the chassis maker. In answer to your question the topic had been discussed a number of times and there are two views as to your legal position if you were to load the caravan to an axle load of 1500kg. I’ve yet to see any details from court cases/DVSA that rule either way but my view tends to err in favour of the lower MTPLM as set by the caravan designer/ builder. As they have set the MTPLM at 1310kg with tyres rated to suit that weight, and they know the weight distribution of the van and will during development have tested it on towing trials. A caravan is different to your normal trailer which just carries stuff to and fro and generally is loaded low down. Your higher axle rating is most probably down to the fact that the maker decided to rationalise production by having one axle set for a number of different caravan models.

Cheers. I have a trip pencilled in to a local weighbridge to see where we are relative to the capacity. We think we are being frugal at the moment but having just struggled to fit a motormover I realise I've added a bunch more weight so better safe than sorry.

If I'm underweight I know we can add a bit more stuff. If overweight we can work out what we need to shift into the car or get shot of. Ideally want to keep the van as light as possible as we plan a few mountain passes in the summer.

Given the higher axle rating you may be able to buy a MTPLM upgrade from Eldiss to give you a bit more margin, but I doubt they would take it right up to 1500kg. But with any consideration of an upgrade you then need to check tyre Load Indexes, and the car’s specification too, including the specification for the towbar as well.

Hello Clive,
In this case I seriously doubt the MTPLM can be raised: the plate the manufacturer may change is the NCC sticker, not gas locker one. The NCC plate already matches the trailers EU plate.
