(approximately)? I want to know so I can guesstimate how many I can put in the back of my car. -- Chris Green |

I don't think I'd want to carry 5 at once in my car. OK, they weigh about the same as 5 people - but you'll still presumably have a driver?! Also, the distribution is likely result in far more load on the back wheels than when you have 5 people in the car. For most cars, 3 at a time would probably be a sensible limit. -- Cheers, Set Square ______ Please reply to newsgroup. Reply address is invalid.

How much does a 'standard' paving slab weigh?
Look in your handbook for the maximum permitted tow hook weight to get an
idea of what the boot can cope with. You can go up slightly on that, because the moment arm is less, but not by much. The maximum tow bar weight has very little to do with the rear axle maximum weight. Almost no car will allow more than 100kg on the towbar (whilst 75kg is more normal) whilst the majority will allow you to exceed that as useful load on the rear axle. Remember that when towing with a 70kg noseweight, you are still allowed to use the boot, provided you don't exceed MAM or GTW. As a very rough estimate, you can fill the boot with half the useful load (MAM-kerb weight) of the vehicle. However, if you are cutting it that fine, then you should book an appointment at a public weigh station and check it. You will then have a much better feel for how much you can take in one go, which may be very useful for the future, or if you will need many trips. Note that you can't be done for being overweight on a trip to the weigh point, provided you don't take the **** and can justify your calculations. Overloading vehicles is dangerous and you can get really quite severe penalties for it, but the fact that you asked the question suggests that you have the right attitude. I saw a complete nutter loading up in B&Q a few weeks ago. He had a Ford Tourneo (small minibus transit van) that required him to place almost the entire load behind the rear axle. A quick calculation showed that he loaded over a tonne into that gap. I reckon he exceed not only MAM by around 200kg, but the rear axle weight by a whopping 500kg. I seriously considered phoning the police, whilst this nutter thought it was a great laugh trying to squeeze in one more dense concrete block or bag of plaster. When it comes to building materials, vans and cars are seriously weight limited, not volume. Christian. |
How much does a 'standard' paving slab weigh?
I've checked the XM specifications, maximum payload is between 500 and
550kg according to model, so 5 slabs should be OK (350kg plus me). Put this would require even loading. Check the rear axle limit and make sure you don't exceed it. Alternatively, spread the load throughout. Put a slab in the passenger seat and two either side of the back seat. The remaining two can go in the boot. This will ensure you can use the full load available. I've also found the maximum towing weight which is way more than I thought it was - can I even pull a two horse trailer legally, wow! Be careful. Often the legal weight limit published by the car manufacturer is too high for safety and is based on getting the thing going on a certain slope. However, to prevent instability and snaking, you shouldn't exceed 85% of your car's kerb weight, which is usually less than the published braked trailer limit. An experienced tower could get away with 100% of kerb weight, but don't do this until experienced and NEVER exceed 60mph with a trailer. It isn't big, it isn't clever and may kill someone. Instability can bite suddenly at high speed and it is very easy to forget that you have the trailer on the back (at least it is for me, as the van is wide enough to obscure most trailers).

There is *no* "legal weight limit" for cars in the UK. See:-
Just because there isn't a specific infringement, doesn't make it legal. I bet if you towed a full 3500kg behind a car they'd still do you. Whether it is under construction and use, or just simply dangerous driving or whatever, they'd still issue a prohibition and may prosecute. Saying to the magistrate that the fact that you've towed a 3500kg trailer whilst the vehicle manufacturer says anything over 1300kg is dangerous, and you'll see what I mean. Christian. |

In determining the state of the vehicle for this purpose, regard may be had to anything attached to or carried on or in it and to the manner in which it is attached or carried.

Saying to the magistrate that the fact that you've towed a 3500kg trailer whilst the vehicle manufacturer says anything over 1300kg is dangerous, and you'll see what I mean. As I said before there is no legal maximum limit. The law does not state that if you exceed a specified trailer weight it then becomes automatically illegal. I think you'll find in fact that there is no maximum trailer weight specified (as a recommended maximum) for many cars, especially older ones. I quite agree (and so does the URL I posted) that if you exceed the manufacturer's recommended weight it will be used as part of the evidence if you get prosecuted for having a dangerous load or some such. however you can't be prosecuted specifically for 'too much weight' because there isn't a weight limit. -- Chris Green |
How much does a 'standard' paving slab weigh?
however you can't be prosecuted specifically for 'too much weight' because
there isn't a weight limit. For the vast overwhelming majority of cars sold in the last 30 years, the manufacturers publish a limit. Just because that limit isn't totally supported by specific legislation doesn't mean that you won't get done for dangerous driving by exceeding it. The manufacturers have stated that, in their opinion, the car is dangerous to drive above that weight. If you want to defend yourself, you have to explain why the designers of the vehicle know less about the safe towing limit than you do. Also, I'd guess a 'DD40' conviction would be worse on your record than a 'CU50'. Getting insurance with a DD code on your licence must be pretty damn hard. Note that there are loads of things you may be prosecuted for whilst driving that don't have a specific piece of legislation. They are just prosecuted under a general careless or dangerous driving charge. Christian. |

You can also be prosecuted for careless/dangerous driving if you go round a corner too fast but lower than the speed limit. However you wouldn't thus say "there is a legal speed limit on this corner (that is lower than the general speed limit)". -- Chris Green |

You can also be prosecuted for careless/dangerous driving if you
go round a corner too fast but lower than the speed limit. But the manufacturer's limits are much better defined than a speed round a corner, so although they would be prosecuted under a general provision, the offence is likely to be accurately determined by your failure to comply with the manufacturer's recommendations. In fact, your failure to do so can probably be measured more accurately than your speed! Christian. |

Since they were being given to me free I could hardly "have them delivered". Anyway we collected them five at a time last night, spread them around on the floor with the rear seats down. The XM's self levelling suspension coped fine, just a few clicks of the hydraulic pump after loading them and it was back to the normal ride height. The car handled quite normally with no problems although of course I was relatively cautious. 400kg is well within the maximum load so that was to be expected I suppose. -- Chris Green |
