Earlier this week, as I’m sure most of you know by now, the broadcaster Dan Walker was involved in a nasty collision with a motorist while riding his bike.
Footage has since emerged of the terrifying spill, captured on a motorist’s rear-view camera, which shows the Channel 5 presenter riding on the busy Moore Street roundabout near Sheffield’s city centre, before a driver veers across into his lane, clipping him from behind and sending him clattering to the ground.

A clear case, then, of careless, or some may argue dangerous, driving, which left Walker with a bloodied and bruised face and feeling “glad to be alive”.
So, why then did the former BBC Breakfast host become the centre of a social media storm this week, one which appears to have divided cyclists into two distinct camps?
The whole furore, which Walker has himself addressed both on Twitter and in an article for the Sunday Times, stems from a seemingly innocent comment he made on the day of the collision concerning the usefulness of his helmet.
The helmet I was wearing saved my life today so - if you’re on a bike - get one on your head.
Smashed my watch & phone, ruined my trousers, my bike is a mess but I’m still here 🙏🏻

The 45-year-old claimed that a police officer and paramedics who attended the scene told him that he wouldn’t be here now if it weren’t for his helmet, a revelation that prompted Walker to inform his Twitter followers to “get one on your head” when riding their bikes.
The fact that the presenter chose to focus on his helmet as the one variable that affected the outcome of the collision appeared to some on social media to suggest that, in Walkers’ eyes, bike helmets are an integral component of cycling safety, and that if everyone wore one more lives would be saved on the road.
That suggestion provoked two distinct sets of responses, crudely summarised as follows:
It’s odd to get lectured by people telling me that bike helmets aren’t important when the emergency services at the scene yesterday told me I probably wouldn’t be here if I wasn’t wearing one.
Funny old world! I hope you’re having a good Tuesday.

The presenter addressed these two points of view in a Sunday Times article about the incident (which also touched on the anti-cyclist reaction from motorists unhappy that Walker was riding on “their roundabout”) and in particular the claim that, by urging others to wear helmets, he was “doing the heavy lifting for militant drivers”.
“My helmet is smashed and I’m glad that it wasn’t my head,” Walker writes. “I have always worn a helmet since I attended an awful traffic accident in Manchester when I first started out as a journalist.
“Every police officer can tell you about a cyclist’s head they have had to try to put back together at a road traffic accident so they can be identified by their loved ones. They are never wearing a helmet.”
The presenter concluded the article by suggesting a new campaign slogan for cyclists, based on a message sent to him by a well-wisher this week: “Don’t be a helmet. Wear a helmet”.
While it’s clear that Walker never intended to provoke such a heated debate with what on the face of it seemed a fairly innocuous comment, relayed to him by an emergency services member in the wake of a traumatic crash, the backlash that followed his tweet – and the presenter’s own response to it – has nevertheless highlighted the complicated and often confusing relationship between helmets and road safety.
Should everyone riding a bike, as Walker claims, wear a helmet to keep them safe? And, to stretch the presenter’s point to its logical conclusion, should helmet wearing be made mandatory?
Chris Boardman, the former Olympic champion-turned-active travel champion, doesn’t think so. In fact, back in 2014, the then-British Cycling policy advisor described the “helmet issue” as a “massive red herring” which is “not even in the top ten of things you need to do to keep cycling safe or more widely, save the most lives”.
There are a number of case studies which support Boardman’s stance, perhaps the most famous – and hotly-debated – of which was conducted by psychologist Dr Ian Walker of the University of Bath, who concluded that motorists tend to give more space to cyclists not wearing helmets, therefore lowering the possibility of a collision, and the potentially grisly consequences outlined in Dan’s Sunday Times piece, in the first place.
So, what role, if any, do helmets play in keeping cyclists safe? This most divisive of issues can be split into two discrete factors: the scientific and the societal.
When it comes to the science around helmets, the answer is: it’s complicated.
A 2017 review by statisticians at the University of New South Wales found that, based on 40 separate studies, helmet use significantly reduced the odds of head injury, and that the probability of suffering a fatal head injury was lower when cyclists wore a helmet (though, the authors noted, helmets cannot eliminate the risk of injury entirely).
Another study from the same year, this time from Norway’s Institute of Transport Economics, concluded – based on an overview of almost 30 years’ worth of analysis – that bike helmets reduced head injury by 48 percent, serious head injury by 60 percent, traumatic brain injury by 53 percent, facial injury by 23 percent, and the total number of killed or seriously injured cyclists by 34 percent.
The protective ability of helmets has also increased in recent years, thanks to the use of different materials in the design process and the advent of technologies such as MIPS, designed to reduce rotational motion to the brain in the event of a crash.
However, while they are certainly useful when it comes to lessening the potential severity of a serious head injury, helmets have proved markedly less effective when it comes to preventing concussion, a reality of their protective limitations recognised by only one in five competitive cyclists, according to a recent study.
“Our conclusions are not that cycling headgear doesn’t afford protection, but that more independent research underpinning new technologies marketed for reducing concussion is needed,” said the study’s lead, and former racing cyclist, Dr Jack Hardwicke last year.
However, perhaps the most important limitation associated with helmets – and one that is particularly pertinent in Dan Walker’s case – is their ability, or rather, their inability to protect riders involved in collisions with a vehicle.
In 2020, Eric Richter, the senior brand development manager at helmet manufacturer Giro, sought to clarify the “many misconceptions” about helmets.
“We do not design helmets specifically to reduce chances or severity of injury when impacts involve a car,” Richter said.
Current bike helmet testing procedures are fairly rudimentary, involving helmets being dropped from different heights on either a flat or an angled surface, and do not take into account collisions with vehicles.
According to Richter, “the number of variables” – including the speed, mass, and profile of the vehicle, as well as the angle of impact – “is too great to calculate”.
Despite their ability to prevent serious head injuries, helmets then, as Giro points out, are not designed to protect cyclists from dangerous drivers. Which brings us onto the second major factor influencing the role of the helmet in the wider road safety discussion: societal and cultural norms.
In the UK, a nation where proper, protected cycling infrastructure is in its infancy, and can at best be described as geographically variable, helmets have long played a central role in cycling culture.
Right from the time your parents popped off the stabilisers on your first bike, the call to ‘wear your helmet’ has been a constant one. So, it stands to reason that helmet use must lead to safer cycling, right?
In 2016, a study by the Toole Design Group analysed the correlation between helmet use and fatality rates amongst cyclists on the roads in eight countries.
The Netherlands – the world leader for safe cycling infrastructure with a strong bike riding culture – reported the lowest rates of helmet use and the lowest cycling fatality rate per distance travelled.
On the other hand, the USA, of the eight countries examined, reported the highest rate of helmet use. But it also reported the highest fatality rates too.
In his Sunday Times article, Dan Walker noted the gulf in infrastructure and culture between the Netherlands and the likes of the UK, which he argues provides all the more reason for British cyclists to don helmets out on the road.
“I have cycled in Amsterdam where ‘hardly anyone wears a helmet’ and it’s great, but the whole transport culture revolves around two wheels,” he says.
“In the UK, we don’t have the same respect for vulnerable road users. I have witnessed terrible driving and awful cycling everywhere. We desperately need better infrastructure, better training, and more respect for other road users, but a bike is never going to win a tussle with a car and the questions always seem to be centred around what a cyclist should do to stop getting killed, rather than safer driving.”
On the other hand, the kind of figures presented by the Toole Design Group could also be used to add credence to Ian Walker’s theory that, in some motorists’ eyes, helmets can represent a kind of protective shield which seemingly permits them to drive dangerously around lid-wearing cyclists – despite, as Giro have said, their dubious effects when on the receiving end of a two-tonne vehicle.
Another study from 2019, presented at the National Road Safety Conference, also suggested “a higher accident/injury rate may result from helmet usage” and argued that “there is strong evidence that helmeted cyclists suffer a higher rate of upper body limb injuries than non-wearers, suggesting a higher rate of falls than non-wearers.”
As Chris Boardman noted over nine years ago, it’s clear that simply reinforcing the notion that reactive protective gear such as helmets and hi-vis clothing are an essential element of everyday cycling cannot simply act as a replacement to proactively building safe cycling infrastructure and addressing driver behaviour.
“It’s a bit like saying ‘people are sniping at you going down this street, so put some body armour on,’” Boardman said in 2014.

Encouragement to wear helmets, either from governments or TV presenters on Twitter, are according to Boardman’s analogy “a big campaign to get people to wear body armour, by the people who should be stopping the shooting.”
The chair of the Road Danger Reduction Forum, Dr Robert Davis, was one of the most prominent critics of Walker’s claim that his helmet “saved” his life, and has argued that such a claim feeds into society’s inherent anti-cyclist bias and acts as a “red herring”.
Culturally defined safety measures such as helmets, lights, and hi-vis, Davis says, “can act as a diversion from what needs to be done for real road safety”, placing the onus once again on the more vulnerable road user to be wholly responsible for their safety.
Davis’ vocal criticism of Walker’s call for cyclists to wear helmets is, in many respects, a kind of self-fulfilling prophecy.
With cyclists – a group, you would imagine, united in the goal of making the act of riding a bike as safe as possible – at loggerheads over a safety issue such as helmets, attention naturally was diverted from the dangerous driving that caused the Channel 5 presenter to clatter to the ground with an unceremonious thump.
By focusing on helmets (and their contentious ability to mitigate the effects of a collision with a car, such as the one suffered by Walker), the ability and desire to tackle dangerous driving, as well as creating suitable, safe spaces for cyclists, is impeded – and the blame shifted away from the dangerous driver and back onto the vulnerable road user.
Finally, the implication, spread by Walker, that his helmet was crucial in saving his life raised the inevitable question: Should all cyclists wear helmets at all times?
That was certainly the argument put forward this week by Nick Freeman, the lawyer nicknamed ‘Mr Loophole’ for his ability to obtain not guilty verdicts for celebrities charged with motoring offences.
Speaking to BBC Three Counties Radio’s Jonathan Vernon-Smith in the wake of Walker’s crash, Freeman called on bike helmets to be made compulsory for cyclists.
“Cyclists are so vulnerable,” he said. “They are exposed to massive dangers on the road from motorists, from the road surface itself, and it just seems to be common sense to say you need to wear these items to protect yourself.
“It’s going to be a mandatory requirement because, as Dan Walker very happily said, it saved his life. Irrespective of blame.
“We all make mistakes when we’re cycling, we all make mistakes when we’re driving, but if those mistakes could be fatal and that could be avoided by simply wearing something, then surely as a society we have no choice, we have to adopt that.”
However, despite Freeman’s claims, the issue around mandatory helmets is not quite as simple as that.
In December, the Department for Transport insisted that the UK government has “no intention” of making wearing a helmet while cycling a legal requirement.
Minister of state for the department, Jesse Norman, responded to a question on the matter in the House of Commons by pointing out that the issue had been considered “at length” during the cycling and walking safety review in 2018.
Norman said that while the Department for Transport “recommends that cyclists wear helmets”, the “safety benefits of mandating cycle helmets are likely to be outweighed by the fact that this would put some people off cycling”.
The UK government’s approach to mandatory helmets is in line with a school of thought which suggests that mandatory bike helmets – and their apparently inherent association with danger and the need to protect yourself – could discourage cycling, which on balance is much healthier for the population to practice without protective equipment, rather than simply not doing it at all.
In Australia and New Zealand, two of only four countries in the world to have implemented a universal, nationwide helmet requirement (the others being Argentina and Cyprus), the number of people cycling has fallen in the thirty years since the laws were introduced.
A recent analysis of census data found that, since New Zealand made helmets mandatory in 1994, children’s cycling “reduced from 23 million hours to 13.6 million hours in less than a ten-year period and currently is about four to five million hours per year”.
A 2019 article by law professors Julia Quilter and Russell Hogg argued that Australia’s mandatory helmet laws “have become a tool of disproportionate penalties and aggressive policing”, with failure to wear a cycling helmet the most-commonly issued on-the-spot fine in New South Wales.
In the US city Seattle, mandatory cycling helmet laws were dropped in February last year after officials expressed concerns about the laws unfairly impacting black people and the homeless.
One of Australia’s most prominent opponents of the mandatory helmet laws, Sue Abbott, says that “it beggars belief that in the 21st century we take something as benign and beneficial as bike riding and we punish people.”
Todd added: “We accept that a helmet might help in the event of an accident … [but] you must distinguish between crash data and population data. It hasn’t had any measured safety benefit at the population level. Across population, the reduction in injuries was no more than the drop in cycling.”
Meanwhile, Edward Hore, the president of the Australian Cycle Alliance, argued that wearing a helmet “should be a choice”.
“We’re not talking about banning helmets, we’re talking about making them optional,” he said.
“If you’re in a peloton down a beach road, and you’re not wearing a helmet, you’re a bloody idiot, let’s be frank.
“But we’re talking about the rider in the park with a family, the local commuter, the gentle ride down the street. Once you’ve measured your risk you can decide whether or not you want to don a helmet.”
In many respects, the fierce social media debate that arose in the wake of Dan Walker’s call for cyclists to wear helmets is evidence of one group engaging in two separate conversations at the same time.
Yes, helmets are certainly beneficial, and in some cases essential, and can play a key role in preventing and reducing serious head injuries and fatalities.
But they cannot be viewed as a simple like-for-like replacement for safe infrastructure and addressing dangerous driving at its source.
By placing the helmet at the centre of a discussion concerning a high-profile and well-reported collision between a cyclist and a motorist, the onus for road safety – as Walker himself noted in his Sunday Times piece – is once again “centred around what a cyclist should do to stop getting killed, rather than safer driving”.
The social media storm that engulfed Walker’s bike helmet advocacy is perhaps indicative of the fact that most cyclists are unaware of the two-sided nature of the debate – he clearly didn’t intend it to be a loaded statement, it’s his opinion and choice to wear a helmet while cycling, and he meant no harm by what he said.
However, as we’ve noted above, there is plenty of evidence to support the view that he could have used his profile to promote things that are shown to improve cyclists’ safety much more than protective equipment.
Nevertheless, there could have been a whole host of reasons why he didn’t though, and it’s understandable that after such a nasty and traumatic experience he was just thankful for the equipment that he was told prevented his injuries from being much worse.
There’s nothing wrong with wearing a bike helmet – as odd as calling for all cyclists to wear a helmet is, it’s arguably just as weird to be actively against helmet wearing in all instances – and lots of studies have outlined their benefits.
Cycling overall though is a relatively low risk activity, especially when riding on designated cycling infrastructure at low speeds, and, as has been the case in Australia and New Zealand, mandating helmet use only puts people off riding their bikes.
To paraphrase Dan Walker himself, don’t be a helmet – make your own choice.
