Speed humps are causing ‘too much’ damage to cars, new research reveals

• Councils have forked out more than £35k to drivers for damage caused by speed humps(1) between 2015 and 2017 – but not all drivers are entitled to compensation.
• More than 29,000 speed humps are installed across the UK(1) – but one in six (17%) drivers are confused about why they are used over other speed calming measures.
• More than a quarter (28%) of UK drivers think markings on speed humps should be made clearer, as a further one in four (27%) think they are not an effective method of reducing speed.
• Councils across London have paid out more than £16,000 alone to drivers for speed hump damage(1).

Speed humps are installed on roads across the UK in a bid to improve safety. However new research suggests that they are giving motorists a bumpy ride and are causing ‘too much’ damage to cars. 

New research by Confused.com revealed that more than two fifths (41%) of UK motorists think speed humps, bumps or cushions cause too much damage to cars. In fact, more than one in five (22%) drivers who have driven over a bump in the road said it damaged their car, costing them an eye-watering £141 to repair, on average. Most (48%) received a defect on their tyres, while a third (33%) said it broke their suspension.

However, some motorists have been able to claim this money back from councils. New data obtained by Confused.com through Freedom of Information requests to the UK’s local councils revealed that a whopping £35,080 was paid out to drivers between 2015 and 2017 for damage caused by speed humps(1). This is despite the fact they are not technically classed as a ‘road defect’, making it difficult for drivers to make a claim.

According to the data, more than 29,000 speed humps, bumps and cushions are installed on roads(1) with lower speed limits to encourage drivers to slow down, however some drivers are unsure why this is. Further research by the driver savings site found that one in six (17%) UK drivers are confused about why councils use them over other speed calming measures. In fact, motorists find permanent and police enforced speed cameras, and chicanes to be more effective, with one in four (27%) saying they think speed humps are ineffective in reducing speeds. 

Not only this, but many drivers also find speed humps hard to spot on the road, with more than a quarter (28%) wanting to see road markings and signage made clearer. And this means some motorists may come across an unexpected bump in the road, and haven’t been able to slow down in time, which could potentially cause damage to their car.

And there may be some confusion about when drivers can claim for damage caused by a speed hump. Highways Regulations state drivers may claim for damage to their vehicle if the road surface is defected(2). However, as speed humps are placed by the local authority as a speed calming measure, they are not technically classed as a road defect. But there are limitations on how big a speed hump should be, and this might make it easier for motorists to claim compensation for damage. According to the Highways Regulations 1999, road humps should not exceed 100mm in height(3). Anything higher than this is more likely to cause damage to a car, and puts motorists in a position to claim for damage caused. However, the government recommends they are no higher than 75mm(4), and the data obtained from local councils suggests that the average maximum height of speed humps installed across the country is 72mm. But, worryingly, there are few motorists who are aware of the maximum height speed humps should be. According to the research, one in six (17%) believe it to be 75mm, while almost one in five (18%) think it is 100mm. 

Looking at the data in more detail, it’s clear some regions are more of a bumpy ride for drivers than others. In particular, speed humps installed in London have caused £15,717 worth of damage to cars between 2015 and 2017(1). In total, 8,516 speed humps, bumps or cushions are installed across the capital, which has arguably some of the lowest-speed and congested roads in the country.

Motorists should approach all speed humps, bumps, cushions or tables carefully and reduce their speed to avoid catching their car and causing any costly damage to their car. Although, worryingly, almost a third (29%) of drivers admit they speed up in between humps, almost one in five (19%) don’t always slow down when driving over them. Some (12%) even go as far as saying they don’t encourage them to drive slower. And it is this that is most likely to be causing damage to cars.

However, it’s no wonder speed humps are unpopular among motorists, with almost a quarter (23%) admitting they avoid driving down roads with speed humps. And there are many reasons why drivers don’t like them. Almost a third (31%) think they make roads look ugly, while more than one in four (27%) think they cause disruptions to traffic flow, which can make roads quite chaotic. But over one in five (22%) drivers are also against the use of speed humps because they are bad for air pollution. 

Recent research has suggested that speed humps damage roadside air quality, due to the constant slowing down and speeding up required by cars, which increases emissions. And some drivers feel quite strongly about this, with almost one in four (23%) calling for speed humps to be removed in order to improve air quality. Some (33%) also think that it is unclear exactly what impact speed cushions have on air quality and think that more research needs to be done to clear up any confusion.

However, there are also some drivers who see the benefit of speed humps. Almost half of UK drivers think they protect pedestrians from speeding cars, while just over two fifths (44%) say they improve road safety. Although, unsurprisingly, the majority of drivers also think that more needs to be done to avoid damage to cars, with almost three in five (58%) wanting to see them made lower. But perhaps with clearer markings, motorists would be more cautious when driving over speed humps, which will ultimately avoid any damage.

“But forking out hundreds of pounds to fix tyres or suspension is a cost we’re sure drivers could do without, when the cost of motoring is becoming less affordable as it is. Drivers should cut through the clutter of motoring chaos by shopping around and comparing the best deals using a site like Confused.com, or read our go-to guide on how to reduce car insurance costs.”
