Active travel campaigners call for higher taxes on “supersized” SUVs to tackle “carspreading”, claiming they are more dangerous to cyclists and pedestrians and cause more pothole damage

“It’s only fair if you want to buy a massive SUV that you should expect to pay more for the space it takes up,” the campaigners said, pointing out that only 18% don’t want to see additional charges on SUVs

Active travel campaigners from the UK are calling for higher taxes on the owners of “supersized” SUV to tackle the phenomenon of “carspreading”, pointing out that academic studies show them to be more dangerous to cyclists, pedestrians, and smaller car users, as well as causing more pothole damage while also being unable to fit in most parking spaces.

A YouGov survey conducted in January found that only 18 per cent car owners in Britain held the belief that there shouldn’t be any additional charges on SUV owners. Clean Cities, a European active travel organisation campaigning for healthy and climate-friendly transport, has pointed to this study to demand changes in the current auto taxation system.

Its researchers found that since 2021, around 4.6 million cars have been sold in the UK, which were bigger than a typical urban car parking space — more than 1.2 million a year, with SUV sales figures pointing upwards.

“Supersized” SUVs, which the campaign described as being either more than 1.8m wide or 4.8m long, have been growing in popularity despite them crowding out space in towns and cities, causing more road wear and being more likely to cause fatal injuries for children, cyclists and those driving smaller cars.

> SUVs more dangerous to cyclists than other cars, study suggests

It claimed that if you were to add up just the extra length and width that overhanging SUVs take up, it would stretch for over 192 miles, the equivalent of driving from London to Leeds. 

Oliver Lord, UK Head of Clean Cities, said: “Cars are getting bigger every year — while our streets are not. We need carmakers to prioritise normal-sized cars that can be parked more easily and are less dangerous to people walking around. It’s only fair if you want to buy a massive SUV that you should expect to pay more for the space it takes up.”

To tackle the phenomenon known as “carspreading”, the campaigners are calling for fairer taxes in favour of lighter and more appropriately sized cars and for parking costs in cities to be based on the size of a car.

A new academic paper, published earlier this week, shows that heavier cars are more likely to be involved in fatal collisions, and average car weight in the UK is increasing. 

This may lead to a rise in fatal collisions if the trend continues, the academics warn. Reducing car weight could mitigate the severity and frequency of collisions, while academics suggested that policymakers could consider “taxation on heavier cars” and that “local authorities could adjust parking policies to charge higher fees for heavier cars”.

The study, led by civil engineer Ruth Carlson and co-authored by Nima Dadashzadeh, assistant professor in transport and business analytics at the University of Huddersfield, is based on preliminary findings with the full paper out later this year. 

> SUVs 'eight times more dangerous' to kids walking or cycling than smaller cars are

New taxes could reap significant rewards for HM Treasury and the Department of Transport. As well as the additional revenue, discouraging sales of heavier cars could reduce road maintenance costs.

According to ‘the fourth power law’’, a formula developed by US Highway Officials, the damage done by a vehicle to a road surface is proportional to the fourth power of its axle weight.

A two-tonne SUV therefore does 16 times more damage than a one-tonne car. The potholing of road surfaces is even worse when it rains because heavier vehicles create much stronger hydraulic pressure, forcing water into any flaws and breaking up the road surface.

Harriet Edwards, a concerned parent from Sutton, said, “It’s not just the added stress of not being able to find somewhere to park, it’s the sense that if I’m involved in a collision with one of these giant SUVs, that me and my family are far more likely to be seriously hurt or killed.

“If you cause more danger, create more potholes and take up more parking space, it’s only fair that you pay a little bit more.”

Figures from the RAC show drivers encounter an average of six potholes per mile in England and Wales and the cost of pothole damage to vehicles is around £500 on average, with more severe repairs costing considerably more. According to the AA, fixing potholes is a priority for 96% of drivers. 

Edmund King, the president of the AA, is on record as saying: “Better maintenance of the road network is the number one concern of drivers as damage costs a fortune and potholes can be fatal for those on two wheels.”

According to the YouGov polling, 61 per cent of UK passenger car owners agree that “SUVs take up too much space”, while only 19 per cent disagree. Further, 71 per cent of car owners also agree that SUVs make parking more difficult, while only 15 per cent disagree.

A 2023 study from the US also found that SUVs are causing more cyclist injuries, with crashes with SUVs resulting in 55 per cent more trauma and 63 per cent more head injuries than crashes with cars, owing to taller front-end designs.

A year prior, another US study showed that SUVs are eight times more dangerous to kids walking or cycling than smaller cars are. It also found that although SUVs are involved in much fewer crashes than standard cars, they are twice as fatal.

It's not just SUVs that are too big. Cars are generally getting longer and wider. We have just bought a Skoda Octavia as we needed a family car, and although it's not an SUV, it's over 1.8m wide and nearly 4.8m long. It is a TARDIS inside though, unlike an SUV. Manufacturers should be looking at ways to reverse the inflation trend.

I see these clogging up my street every day on the school run.  Daft thing is that most of them only live 15 minutes or less walk away from the primary school across the road. These are totally unneccessary in an urban environment and are a real safety hazzard. Hike the taxes, then we'll see who really needs them.

What a load of crap here. Whoever thinks that people does not need big car, I'm afraid it's not for you to decide. If you think that there is more suv than hgv well you will be surprised how many hgv's there is on the road. By the way how many times I could see cyclist riding through red light just because they can is unreal, but well blame suv's for it or other cars.

Thanks for the warning, but it's redundant.

Size is relative so Kei car and truck drivers will be pointing at almost everyone in Europe though...

You'll find that every society makes overt and covert rules about what is "need" vs. "want" vs. "thou shalt not" - which is not entirely linked to practical considerations on a single level. So that's always a question.

Perhaps they didn't "need" to travel, or not in that way? Maybe society as a whole "needs" vehicles more like the size shown in the picture rather than vehicles which primarily (initially) allowed US manufacturers to avoid taxes and also upsell consumers on vehicles which generated more profit despite being less practical for almost every conceivable purpose (except display)?

A lot of large SUV drivers seem to be large. Maybe owning a large, wide car makes them feel smaller.

I remember some research from 20+ years ago which showed that buying a motorcycle was associated with gaining weight, so maybe it applies to SUVs too.

Long overdue and fully justified.

A massive fail on country B-roads where the hints of off road capability are no help in overcoming the excess width and weight. Makes a normal two lane road into a single track with passing places.

My son really didn't want to go to school this morning.  We managed to get him to go, but as he was running late I said I'd take him on the GSD.  We would have made it in time, except we got stuck behind a Range Rover struggling to squeeze down a residential street with cars parked (and in the process of parking/dropping off) on either side of the road.  But, of course, it's only ever cyclists who hold up drivers...

LOL , me too the other day, I was on my GSD and got stuck behind a Cadillac Escalade (I think that is what they are called). It was so fat and over sized it couldn't get down Highgate West Hill without stopping and squeezing past every passing vehicle. And then a single decker bus came up the hill.

I've actually given up taking most of my backstreet shortcuts in Kensington and Chelsea because it's better than 50-50 odds that you'll come up against someone in a wankpanzer inching down the street at 5 mph desperately trying not to scratch their precious. As I suggested elsewhere, width restrictions at the entry/exit point of narrow streets would do a lot to stamp out this madness and definitely make people think twice about buying them.

Ah, but refuse trucks / fire engines / ambulances ... oh and the single disability- adapted vehicle on the block (like in the Bristol LTN case).

Ergo we can't restrict a substantial minority essentially taking the mick / doing what humans always do (conspicuous consumption) and which some companies are always keen to make possible (upselling people on stuff that has that as it's primary purpose and who cares about more widely distributed negative effects).

But we could have ANPR cameras automatically issuing sanctions to vehicles over a certain width who ignore posted restrictions, no physical barriers required.

Not in Lancashire you couldn't - WU59UMH 7 years no VED, previously 6 years no MOT, 6 months driving around with a failed MOT, name of the groundworks business and Facebook details on the back, marked as stolen on one website, reported by me for over 2 years, regularly sat outside the pub in Garstang 100 yards from the police station, spent several weeks there after Christmas without moving, even reported to DVLA. Either they haven't worked out how to operate ANPR or they're all switched off all the time here to avoid tiresome work. Not seen it for over a month - probably been sold on to different dodgy owners

Of course ... but the current logic seems to favour "I have bought it so therefore it is my right to use it. If I'm not supposed to it shouldn't have been legal for me to but it in the first place." (See also all kinds of e-thingies).

We do slice- and- dice with categories and road rules, but probably the more complex the less well accepted.

TBH the tail was wagging the dog from the moment the marketeers found that "more expensive, bigger and less practical" could be a *general* market-winner (the "top-of-the-pile" folks have always had demonstrating status as a high priority).

That argument is ignorance of the widespread height and width restrictions to be found on the many minor roads that were originally created for horse traffic or in built up areas and bridges.
Doesn't matter how entitled you imagine yourself, you're not going to win against a bridge height restriction but you might get stuck in tons of bricks.

The issue is we just end up with wider vehicles parked on the road because they won't fit the garage *, and it being more likely that drivers will hit things which may be to their detrimental but isn't good for the houses, bridges, other people's vehicles or indeed cyclists they "scrape by".

* Of course people do that anyway because they use their garage for storing other stuff because the public road in front of their property is "my space". Changing that mentality would be a big change!

Do you mean this woman, who got out to marshall the truck through and is now walking back to said Wankpanzer which is blocking the road again as it waits?

Introduce a large car specific driving test that's harder to pass, requiring more training and a requirement to have a specific large car licence. Actively enforce parking within marked bays.

I'd like to see limits set for vehicle power. For instance a 5-seater vehicle is limited to 100 kW (135 PS/BHP). This would make large and heavy vehicles slower and safer as well as reducing environmental impacts.

And as a recent report in the Guardian showed, a million cars a year are sold in the UK that are too big for standard parking spaces.  Back in the seventies, we called it conspicuous consumption, flaunting your wealth and arrogance.  Tax the pips till they squeak: and then a lot more.
