Damaged springs and speed cushions - treecott
I wonder if there are any legal eagles out there that could possibly help me please.

I have had damage to my coil springs,(three in all) which I feel is as a result of speed cushions installed in the area where I live. These are the only cushions I encounter on any of my journeys. I have contacted my local council, who have said the cushions comply with the Regulations (road humps) 1996. and they have been maintained. I dispute this, but need some help proving it.

The cushions involved are rubberised ones, bolted down to the road surface. In the Regulations 1996 it says that "it has no vertical face of any material forming pat of that road hump exceeding 6mm measured vertically from top to bottom of that face". The cushion edges are indeed 6mm, however, the "on/off" ramps are off the road, and I have measured it, and photographed it as 25mm from road surface to top of cushion. The edges will not stay flat to the road, as debris has got underneath. Also, there are several bolts protruding above the cushions as well.

My question for any legal eagles out there is: Do the speed cushions have to be attached to the road surface?. I cannot find anything on the Regulations which states this, and having contacted the Dept. of Transport, they can only refer me to the Regulations. This appears to be a grey area, and I wonder whether anyone reading this has any experience of this, or have they come across it during their course of legal work.

I would have thought, as a layman, that the speed cushions SHOULD be attached to the road surface all way around, (as the tarmac ones are), however, I cannot find anything in which I can throw at the local council. Any help would be appreciated.

Thanks all.

Damage to springs is more likely to be the result of driving over speed cushions too fast, rather than the design of the speed cushions. Speed cushions are intended to get motorists to moderate their speed, and you ignore this at your peril.

I dislike speed humps as much as the next man, but there is no reason to assume that it should be possible to drive everywhere inside a 30 zone at 30. All kinds of everyday obstacles would prevent this - humps are just one of them. Just be grateful you don't have to drive a loaded fire engine or ambulance.

Full legal dimension of speed cushions here tinyurl.com/mrq982

No vehicle should be damaged in any way by being driven down a road at or below the legal limit. If the Town Hall Stupids want a lower limit they should post it and enforce it. Wrecking people's cars, when being driven in accordance with the legal limits may well be legal, but it shouldn't be!

Quite, AS.

I have just acquired a car that is slower and less robust over horrible stupid speed bumps than my old car, and I am not best pleased.

I'm afraid I can't help with any legal points but I would say that we had these rubber cushions installed in my road outside the local shops. I found them quite high to drive over and also dangerous for pedestrians. I slipped a couple of times, crossing the road, in icy weather. my slightly open car door was clipped by a passing car which lurched to the side on one. Some of the bolt heads protruded as well. These were removed a couple of years ago and painted squares applied where they were. I wonder if the council, Manchester City, had been getting complaints.

It seems to me, from various posts on this forum, that Corsas should only be driven on the smoothest of surfaces !

Good luck.

I consider some of these obstructions to be a disgrace and tantamount to deliberate vandalism. Some have recently been replaced near me (the old ones were tarmac lumps negotiable with care at around 15mph) with what can only be described as pyramidical stacked tiles with a flat top and four sharply angled edges. Within a month of installation these sharp edges had turned black. That is tyre rubber being abraded from the inner edges of vehicle tyres. Dangerous and a vicious swinish thing to do. My technique with these is to virtually stop then take them at less than 10mph in 2nd gear. I don't care who or what is behind me. This is a 30mph feeder road which it is impossible to avoid. I am loath to get a new car to subject it to this every time I go out and return. Perhaps some kind of tracked vehicle, bulldozer or a JCB would be the best personal transport nowadays, or even an old farm tractor and garage my car somewhere else. A friend of my son has a nice Porsche and when he visits he has to put 2 wheels over the top of them rather than attempting to straddle them or there'd be nothing left of the bottom of the car.

There are some pretty nasty speed cushions being installed in Queens Road and Park Road Teddington. Most people straddle them and I'm sure that the front suspension and tyres are being damaged by them. I've taken to driving over the centre of them very slowly either with the o/s or n/s wheels trying to alternate when possible. Is this a better idea than straddling them?

I've had an unusually (for me) concentrated series of European trips recently, and taxis elsewhere drive over speed humps at ferocious speeds, even one guy in a brand new E Class Merc.
The taxis all appeared personalised to the extent that I believe they're owned by their drivers who surely wouldn't drive them in such a way if constant damage resulted.

Nowhere in mainland Europe have I ever encountered speed humps as vicious as some of these here. Holland and Belgium 'pioneered' traffic calming schemes. They work without any sign of damage being caused to vehicles. You don't see them scraped on top, blackened by tyre rubber or surrounded by sundry bits of car. I think you'd have to travel to the far side of Moscow to find roads as atrocious as ours.

I don't really want to keep wittering on about this national disgrace, but do people remember when British car manufacturers used to boast about how their products could cope with horrible Continental road surfaces, the most notorious of which was Belgian pave (cobbles)? They even had a special stretch of it at the MIRA test track. Do manufacturers now test vehicles on the truly atrocious obstacles now deliberately placed on our roads? If not, they certainly should and I would like to see such information available for when I buy my next car. You can't escape the horrible things even by using public transport. I occasionally use my bus pass to avoid extortionate Town Centre parking charges. One time the bus was quite full and I had to sit near the back, where it was suspiciously empty. I soon found out why. As the vehicle negotiated one of the full width horrors I was propelled up in the air completely out of my seat. Anecdotally, the bus drivers claim that maintenance costs for the air suspensions have increased considerably and they regard certain routes as a punishment. Imagine having to cope with the things all day long day in day out. In one nearby town the bus company refused to operate a particular route completely until the vicious brutes were levelled off somewhat. Pity there isn't more of that kind of response.

Whilst I hate these speed bumps/humps/cushions they only exist because a small minority of idiots persisted in blatantly exceeding speed limits in built up areas. So blame the local boy racer types, amongst others, for the introduction of cameras and bumps. Just look at how people drive in areas without any sort of traffic calming to see why local councils have had to resort to these measures.

Damaged springs and speed cushions - datostar
Cushions are soft and elastic items for resting on. Car suspensions are meant to cushion the impact of uneven surfaces. Using this word to describe these things is downright dishonest and another political perversion of language. They are the complete opposite of cushions. I don't mind speed cameras in the least. I object greatly to collective punishments imposed on the entire population for the misdeeds of a minority.

You're being disingenuous, datostar - they are only called cushions because of their shape, which is different from a so-called sleeping policeman; and that description is even less appropriate than 'cushion'. What would you suggest they be called?
Damaged springs and speed cushions - datostar
They're also shaped like teabags. I think 'cushion' was chosen as a nice gentle euphemism. So was sleeping policeman. It's like the Prime Minister telling us there will be growth in Government spending of zero per cent. They're definitely shaped like humps. Quasimodo didn't have a cushion on his back. Lay him on his front and you'd think he was part of a road.
Damaged springs and speed cushions - Andrew-T
They're definitely shaped like humps.


Yes, they are. But with care - and as long as parked cars don't get in the way - cushions (or teabags) can be straddled with almost no effect on the car. You can't avoid a 'sleeping policeman'.
Damaged springs and speed cushions - loonykev
Are you saying that it is better to straddle these cushions, and if so, at a reduced speed or at the (normally) 30mph limit? When I straddle them, I feel a thump up through the suspension and I have read countless articles about damage being done to inner tyre walls.
I have taken to slowing right down and taking them centrally with either both n/s or o/s wheels, alternating as much as possible.
Which is better, straddling, or taking them centrally with one side of the car?
Obstacles or hurdles might be better words to use. Something to be overcome!
Damaged springs and speed cushions - Andrew-T
Are you saying that it is better to straddle these cushions ...


No doubt cushions vary somewhat in size across the country, but the ones I am familiar with make it possible to place a car's wheels on the outer 'wedge' where it is less than an inch higher than the road surface. At about 20mph I don't feel a great disturbance in the car. I suppose if one drove over a lot of them, noticeable wear of the inner shoulders of the tyre might accumulate, but I would be surprised. There are plenty of potholes around with much more damaging edges, to say nothing of kerbs which some drivers happily mount from time to time.

Andrew,
I started my part of this thread by reference to hazardous obstacles which had replaced tarmac humps near me. I repeat, these things have sharp edges and have turned black because they are abrading tyres. This is indisputable. At 5mph over these vicious things there is great disturbance in and of the car, let alone at 20mph. I wish the Highway Authority here would adopt the obviously very mild, indeed innocuous ones which you are familiar with. Today I drove to Belgium to meet my son and drive him home from a Railway Station in Belgium. This involved driving in urban traffic 'calmed' areas. Imaginative and effective solutions included signing, visible changes in surface colouration and texture, road narrowing and yes, gentle humps. At no time did I feel that I or the vehicle was at risk. Then I get back home and on the road approaching my house I am back on the disgusting obstacle course and driving over piles of bricks, knowing that my car is being subjected to stresses it was never designed for and that my tyres are being abraded.

I bought a house in 2003 which was plagued by 70mph taxis and boy racers.
A couple of parked cars were written off at night by kiddies who thought they could handle themselves and lost control.
In 2004 six speed cushions were installed and the street ceased to be a rat run.

These cushions are now in an appalling state and have been reported to the local council.

The one thing I do notice is the impact these cushions have on tyre pressures.
I am often away and the tyres are fine. Back home they need frequent topping up.
It may be coincidence, but after 4-5 years, I think not.

I do reckon the tyres wear out more quickly - about 20% less mileage,
but there is no way I can prove this.

At least the C5 doesn't have the same spring problems...?

I work on a main road where 32 sets of 3 cushions were installed 'to stop joyriders' and of course they didn't but have imposed collective community punishment for 7 years instead.

Many people where I work now drive 35-45mph along the 30mph limit road as after 7 years it is plain to see that the faster you go, the less damage and the more comfortable drive you have. The only people who go slowly are people who are from outside the area. If you get stuck behind one going 15mph your head nearly comes off your shoulders and the suspension bottoms out and coffee slops everywhere, things jump off the seats etc...., yet cruise at >40mph and they just go thunk thunk thunk passing beneath you.

Cars should be able to cope with speed cushions. Broken coil springs seem to be a recent epidemic and my guess it's to do with poorer quality steel. If anyone's to blame it's the car / manufacturers, not the local authority. I would have thought that speed bumps were more likely to cause damage to suspension mountings that to the actual springs.

I agree.

The spring manufacturer will carry out fatigue tests to levels of compression and for numbers of cycles both well in excess of what a spring will experience in the lifetime of a car. However, this won't guarantee there will never be any spring failures, because other factors will affect the actual life of individual samples. In the event of a particular car experiencing three spring failures I would look at such things as (a) were the replacement springs genuine spares, (b) were the replacement springs damaged during the fitting process, (c) were all three failures at the same corner of the car, and (d) is the car subjected to unusually high levels of corrosion. There could well be more to the OP's failures than meets the eye.

Damaged springs and speed cushions - treecott
Thanks L'escargot for your reply, The springs were the original ones on my Corsa Comfort. I agree, othere things could cause the springs to go, but don't you think that in l year, of 903 miles only, for 3 coil springs to go it is a little coincidental that I have to go over these speed cushions? If I only had to travel on flat roads, with no obstacles in my way, I don't think 3 springs would have broken. Perhaps one, maybe at a push 2, but 3, I don't think so. I have had the springs replaced, and I will see how long they last, but unless I find out whether these speed cushions should have ALL edges attached to the road, I cannot hold my council responsible for the damage. This is the crux of my argument, i.e. that they were not maintained. The speed cushion is 6mm as regulations state, but they are 12mm off the road in places. This is why I feel it is the cushions that have damaged the springs, as you hit them with such a 'thump' because they are off the ground.

The care is not subject to high levels of corrosion, and the replacement springs were only fitted in April, it was the original ones that broke.
Damaged springs and speed cushions - Number_Cruncher
The broken springs I've seen have broken in areas where the protective coating has been damaged, and corrosion has assisted the fatigue crack.

The protective coating may either be incorrectly applied from new, or, may be damaged by the progressive action of the coils near the end of the spring which make and lose contact with the spring seat as the suspension bumps and rebounds. This progressive spring action is a means of providing good ride with a spring which stiffens under bump.

It's also true that the coating methods, processes, and materials which were available 10 years ago are no longer allowed for environmental reasons.

As stated by L'escargot, the suspension will have been subject to rigorous fatigue testing - but, this fatigue testing is unlikely to have included a realistic corrosion environment or a realistic distribution of abrasive debris in the lower spring cup.

Most of the thump you might feel inside the car is not borne by the springs. Sudden increases in suspension velocity mean that the damper "stiffens" and reacts most of this load. The spring only reacts a load proportional to the suspension travel relative to the body during the bump.

It will be extremely difficult to prove that any defects on the car were caused by the road features. A reasonable approach might be to demonstrate that a particular oft used road feature was beyond its acceptable geometric tolerance for an extended period of time. However, the measurements of the feature's profile would have to be taken and recorded using a technically acceptable method, and with some care.

It would be amusing to see one of these speed-bumps-wrecked my car cases get to court.

"Yer honour, after driving my car repeatedly over these bumps twice a day for a year, it broke."

"OK, plaintiff, let me check I've understood this. These bumps are on a road near your home, are they not?"

"Yes, yeronnor".

"And the presence of these bumps is indicated by a sign, according to the council. Is this true?"

"Yes, yerronnor, that's correct".

"Good. Now, please can you explain to the court what you understand the purpose of these bumps to be"

"I understand that they are some evil bureaucrat's attempt to make me slow down".

"Good. You are of course entitled to your views about evil, but the court is grateful for your confirmation that you understand that these bumps are intended to make you slow down.

"So now, Mr Plaintiff, let me summarise your encounters with these devices. These bumps are signposted, and you are familiar with them from driving across them twice each day for the last year. Is that correct?"

"Yes, yeronnor. I know these awful things very well indeed, and curse them all the time. Work of the devil, they are".

"And yet despite your detailed knowledge of these speed bumps, you have by your own testimony repeatedly driven your car over them at a speed which caused damage to it. The damage is self-inflicted, so your claim is dismissed. I award costs to the council".

"But yeronor, but but but ...."

"But indeed. It is not in the power of this court to charge you with a motoring offence, but your testimony here provides clear evidence that you repeatedly drove your vehicle at a speed which was excessive for the conditions, and that your driving was reckless. I should warn you that the police may choose to prosecute you for those offences. Now get lost."

The real problem in this argument is that natural mimsers start from the position that these council twerps and the twerps whose bleating they respond to imagine they have been given the right to damage the roads and make them dangerous. It is those who want undamaged roads who may - only may, mind you - get a 'fair hearing if they concentrate on complaining about the 'badly designed' speed humps. Never mind the misconceived ones or the unnecessary ones.

Still, we or some of us have elected these clowns and some of us applaud their insolence and idiocy. It may help to justify our own unnecessarily cautious driving and give us a reason to foist it on everyone else whether they like it or not...

A large part of the problem is the extreme variation in design of hump. Some are slight, and can be taken at the legal limit, whilst others are so extreme that you have to slow to a walking pace, and even then it can be uncomfortable. You cannot always be sure what kind you are approaching. And then there are some that are not marked, due to the paint coming off, and proceeding at the legal limit (30mph) you only realise you are about to hit a hump when it is too late, and the car gets a right rattling. Someone help any motorbiker who meets one of those at night.

In the days of 1 year warranty, I had my wife's 4yr old Clio serviced at a Renault dealer and they called to say both rear springs were broken. I went to have a look and they were broken in exactly the same place and the metal in the break was extremely shiny.

The dealer staff said it would fail MOT and looked dismayed when I told them it had passed its MOT the day before. I asked them to replace the springs FOC and they laughed. I called Renault Customer Service and had a fair but firm conversation with one of their people and 15mins later the dealer called to book it in with Renault picking up the whole bill.

I'm absolutely convinced that they either broke the springs on purpose, or else caused them to break. It a very quick and easy £200 job to change the rear springs on a Clio.

Driving is all about taking into account the hazards/restrictions which exist at the time and acting accordingly. When I learned to drive there were very few of the man-made hazards/restrictions you get nowadays but as they were introduced I had to adapt my driving accordingly. For example, there were
(a) very few stop or give way lines at junctions.
(b) no road markings at crossroads ~ you had to decide yourself where you were going to position yourself on the road
(c) no filter lanes
(d) no rural speed limits
(e) no light-controlled pedestrian crossings
(f) very few bollards or traffic islands
(g) no designated parking spaces at the side of the road
(h) no parking refuges at the side of the road
(i) no pedestrian refuges in the middle of the road
and , of course
(i) no traffic calming humps, cushions, sleeping policemen or whatever
etc
etc
etc

Once they were in place I had to change my driving habits to take them into account. As I approach humps, cushions and sleeping policement I reduce my speed. No probs.

HJ, you#ve posted twice that you have "evidence" that these bumps cause dangerous damage to tyres... so why don't you publish and be damned... i'm sure that if it were true the other motoring journos would held take up the fight...

Damaged springs and speed cushions - treecott
Hi, all, this is an update on my original question in July. I have now been able to claim 75% off my local authority, the other 25% was wear and tear, which I agreed with. The Council were very reluctant to pay out, but having proven to them that the speed cushions DO NOT COMPLY with the Highways (road hump) Regulations 1999, they had no alternative, as I was prepared to take them to court to prove my case. As it happens, i did not need to do that.

Any one out there who has these pre-formed moulded rubber speed cushions, if you are in any doubt as to whether they comply or not, go out with a tape measure, and measure the vertical edge. It should be 6mm from road surface to top of cushion edge. If it is more than 6mm, then it does not comply. I had confirmation from the Dept. of Transport, who advised me that they have issued guidance for local authorities on providing traffic calming, in Local Transport Note 1/07: Traffic Calming, which includes advice on maintenance of road humps. Section 4.3.5 of this note states "iT SHOULD BE REMEMBERED THAT, IF A POORLY MAINTAINED HUMP HAS A VERTICAL UPSTAND OF OVER 6MM, IT WILL NO LONGER BE IN ACCORDANCE WITH THE ROAD HUMP REGULATIONS". LTN 1/07 is available to view on the dft website at www.dft.gov.uk/pgr/road/tpm/ltnotes/.

I have proven to my local authority that the cushions had not been maintained, and as there were bolts protruding, and the edges were raised, they had not carried out their duty and as such, were liable for damage to my car as a consequence of their lack of care.

I feel very strongly about this, as we pay enough to keep cars on the road, without have to pay for repairs which are caused as a consequence of lack of maintenance. It is true that speed humps/cushions damage vehicles tyres,suspension, and springs, it is also true that speed cushions get damaged, and they also have to be maintained/repaired, it seems that too many local authorities neglect their duties on this score, and thousands of motorists are paying for repairs to their cars, when in actual fact they should not have to!. BAN THE SPEED HUMPS!.

In all seriousness, how does driving over speed cushions result in damage to springs?

The dampers will limit the suspension travel to within the design limits, so the springs won't be compressed beyond their design limit. In this application spring load is proportional to the amount of compression and nothing else, so the springs won't be loaded beyond their design limits. I'm sure it's possible for high car loads (full complement of passengers and full boot load etc) to compress the springs to the same amount as when a normally loaded car travels over a speed cushion. I accept that the dampers and damper mountings will receive higher loads over a spring cushion than if the car was travelling on a level road, so I would have expected that it would be these components which would suffer, not the springs.

Perhaps Number_Cruncher or another of the more technically competent forum members can offer an explanation?
