Government response to its “Cycling and Walking Investment Strategy (CWIS) Safety Review”. | Road Danger Reduction Forum
High visibility and helmets: Very disappointing. It does say:”… we believe wearing helmets, and also high-vis clothing, should remain a matter of individual choice rather than imposing additional regulations which would be difficult to enforce”.(8.11), but note that the reason for this is NOT – as we think it should be – an evidence-based approach based on the lack of evidence of benefits of hi-viz and helmets. There is still an assumption that these are basically good interventions, with no evidence referenced at all for hi-viz, and poor evidence for helmets being quoted. Despite the lack of good evidence, the Government is still saying: “we will continue to encourage cyclists, especially children, to wear helmets to protect them…” .

PsyArXiv Preprints | Bicycle helmet wearing is associated with closer overtaking by drivers: A response to Olivier and Walter, 2013
There is a body of research on how driver behaviour might change in response to bicyclists’ appearance. In 2007, Walker published a study suggesting motorists drove closer on average when passing a bicyclist if the rider wore a helmet, potentially increasing the risk of a collision. Olivier and Walter re-analysed the same data in 2013 and claimed helmet wearing was not associated with close vehicle passing. Here we show how Olivier and Walter’s analysis addressed a subtly, but importantly, different question than Walker’s. Their conclusion was based on omitting information about variability in driver behaviour and instead dividing overtakes into two binary categories of ‘close’ and ‘not close’; we demonstrate that they did not justify or address the implications of this choice, did not have sufficient statistical power for their approach, and moreover show that slightly adjusting their definition of ‘close’ would reverse their conclusions. We then present a new analysis of the original dataset, measuring directly the extent to which drivers changed their behaviour in response to helmet wearing. This analysis confirms that drivers did, overall, get closer when the rider wore a helmet.

Emotional reactions to cycle helmet use - ScienceDirect
It has been suggested that the safety benefits of bicycle helmets are limited by risk compensation. The current article tests if previous helmet use influences the response to helmets as a safety intervention. This was investigated in a field experiment where pace and psychophysiological load were measured. We found that after having removed their helmets, routine helmet users cycled more slowly and demonstrated increased psychophysiological load. However, for non-users there was no significant change in either cycling behaviour or psychophysiological load. We discuss the implications of these results for a hypothesis of risk compensation in response to helmet use. We also show that heart rate variability is a promising measure of psychophysiological load in real-world cycling, at least in situations where there is limited physical demand.

Commentary: Why I stopped wearing a bike helmet | CyclingTips
There is a war unfolding and likely escalating in every American city (and in many other countries, too) as communities struggle to decide what our streets will look like in the future. So many projects that aim to provide safer infrastructure for cyclists and pedestrians face fierce opposition from people who would prefer to maintain the status quo — to maintain the primacy of cars.

The loudest voices in that latter group have a consistent tactic to try to marginalize the pleas of cyclists, and helmets have sadly become part of that conversation. In 2018, riding without a helmet has become the corporeal equivalent of rolling through a stop sign — a symbol that you don’t deserve respect or a seat at the table. Few of these people care about your safety or even the public-health costs of bike crashes — they simply want to thrust responsibility on cyclists rather than give us a safe place on the road, or they want to use the helmet issue to discredit us.

China: a return to the “kingdom of bicycles”? | The BMJ
Hu and Yin discuss the major health and environmental benefits of cycling for transport, but then advocate helmet laws, which have resulted in substantial reductions in cycling, e.g. a 48% drop in numbers of teenage cyclists counted in Melbourne a year after the introduction of the helmet law[16].

The recommendation for helmet legislation seems to be misguided. The most likely outcome is that fewer people will cycle than without the law, leading to lost health and environmental benefits, together with increased injury rates from risk compensation and reduced safety in numbers.

Last year I went into some detail about why existing research into the efficacy and safety of helmets for cycling does not come close to the standard of evidence that is normally required and which we would usually demand for a medical intervention (which is what they are). Basically an application to helmets of all those things that Ben Goldacre bangs on about. But I never added an easy to link to contents page when it was complete. So here it is.

How did the BMA get bicycle helmets so wrong? | At War With The Motorist
Which is why British doctors should be embarrassed that the British Medical Association currently lobbies for helmets to be compulsory when riding a bicycle. Imagine if a pharmaceutical company developed a drug which, if administered before receiving a specific kind of traumatic injury, makes that injury easier to treat. Imagine doctors and medical scientists lobbying for it to be compulsory for everybody to take this drug daily, without anybody ever having checked for side-effects.

How has this situation arisen? The policy decision has largely been made on the insistence of A&E consultants and trauma surgeons. Consider the anonymous quotations that are scattered through the BMA’s cycling pages:

Government review considers forcing cyclists to wear hi-vis and helmets · Cycling Weekly · Disqus
>I really don't understand the aversion to them.

The aversion arises from the scentific evidence: the human skull is fairly well-adapted to surviving low speed impacts. There is little evidence that a helmet is much use in the collisions with motor vehicles that are the real source of danger to cyclists. There is however good evidence that making cycle helmets obligatory reduces the uptake of cycling. As the beneficial effect of cycling on the reduction in cardiovascular risk and obesity outweighs the risks of trauma by an order of magnitude
reducing cycling (by harassing cyclists) will actually diminish the public health.
By all means wear one yourself if you want to. Just don't imagine that legislating to make everyone dress just like you leads anywhere good.
The helmet issue is a good means of distracting everyone from the real sources of road danger, however, so the road lobby like to keep it bubbling along.

Brexiteer MP Peter Bone resurrects his cycle helmet compulsion bill | Bicycle Business | BikeBiz
In 2007, Peter Bone, the Tory MP for Wellingborough, and then Secretary of the All-Party Road Traffic Group, introduced a 10 minute rule bill on cycle helmet compulsion for children. The bill failed to win support. However, the MP – one of the leading proponents of Brexit – has returned to one of his pet causes and he has introduced a new bill, which would "require children under 16 to wear a safety helmet when riding a bicycle on a public highway; and for connected purposes."

This private member's bill is expected to have its second reading debate on 1st March. It's unlikely to reach the statute books

Cyclist knocked down by van settles High Court action for €3m
In the High Court on Tuesday, his counsel, Michael Byrne SC, told the judge that liability in the case was conceded.

The settlement also took into account Mr Doroscan was not wearing a cycle helmet, counsel said.

While a helmet was not legally required, that issue had to be taken in to account in the assessment of the case and would account for about 20 per cent contributory negligence on the part of Mr Doroscan.

Cyclist’s brain injury award cut by €750k because he wore no helmet - Sticky Bottle
A cyclist who suffered a brain injury when he was hit by a Dublin van driver has been awarded €3 million.

However, the court was told that the injured man was deemed to have contributed 20 per cent of the negligence to the collision.

That percentage was reflected in the settlement he received, meaning the full sum he would have been awarded was €3.75 million.

The court heard while helmets were not a legal requirement for cyclists in Ireland, the absence of one could still be factored into the calculation of liability and damages in such cases.

The big bike helmet debate: 'You don’t make it safe by forcing cyclists to dress for urban warfare' | Life and style | The Guardian
In 2013 the tireless Ian Walker carried out a more extensive version of his helmet study. It also measured how closely drivers passed a bike when overtaking, but this time – using a volunteer colleague rather than himself – there were seven different outfits. Four made the rider look like a cyclist of varying experience and dedication, ranging from full Lycra to more everyday clothes, including one involving a hi-vis jacket. Three other outfits were based around bright yellow waistcoats bearing written messages. One read, “Novice cyclist: please pass slowly”; another said, “Polite: please slow down” – “polite” is sometimes used by UK cyclists and horse riders in the hope drivers might mistake it for “police” – and finally one read, “Police: camera cyclist”.

This brought data for just under 5,700 overtakes, more or less evenly split between the seven outfits. None of the outfits made an appreciable difference to driver behaviour, apart from the one saying “police”. For the six others, the average passing distance was between about 114cm and 118cm. For “police” it went above 122cm. Similarly, the proportion of drivers who went very near the bike was noticeably lower for the “police” vest. In contrast, the tabard saying “polite” saw the nearest average overtaking distance and almost twice as many potentially dangerous passes as “police”.

The lessons seem clear and worrying. For one thing, no matter which outfit was worn, a small percentage of drivers still overtook dangerously near, at a distance of 50cm or less. More than this, it seemed drivers were perfectly able to distinguish between different types of rider, and to read and absorb any message displayed. But rather than adjusting their driving to the perceived experience of the cyclist, it was only when faced with a threat to their own welfare – a police rider filming their actions – that many allowed a cyclist more space on the road. Most alarming still, some seemed to treat the mild attempt at deception of “polite” as a reason to almost punish the cyclist.

Bosnia becomes first country to repeal a cycle helmet law | Bicycle Business | BikeBiz
Bosnia and Herzegovina has become the first country in the world to repeal an all-ages cycle helmet compulsion law. The campaign to repeal the law was started six years ago by the Centre for Environment group.

"Citizens can now choose whether or not they want to wear a safety helmet," said the Centre for Environment's Tihomir Dakic.

Anti-compulsion campaigners say that mandatory cycle helmet laws undermine efforts to increase cycling by making riding a bike seem more dangerous than it is, then putting the blame on cyclists if a crash does occur.

CR 193: The development of a protective headband for car occupants (2000)
In 1997 McLean et al. (1997) demonstrated that energy absorbing headwear for car occupants might be effective in reducing the numbers of head injuries sustained by car occupants. The estimated benefits were greater than the estimated benefits of padding of the upper interior of vehicles to the requirements of the US Federal Motor Vehicle Safety Standard 201. This report investigates the suitability of selected materials for head protection, in the form of a headband that could be worn by car occupants.

10 arguments contre l’obligation du port du casque à vélo | L'interconnexion n'est plus assurée

Faut-il obliger les personnes se déplaçant à vélo à porter un casque ? C’est le souhait du sénateur Hervé Maurey (UDI, Eure), qui a déposé une proposition de loi en ce sens en février 2016. Depuis, la controverse alimente les gazettes, les radios et les conversations, et le sénateur lui-même confie qu’il ne s’attendait pas à cette soudaine heure de gloire. Le débat n’est pas nouveau et il a, d’une certaine manière, déjà été tranché plusieurs fois. Voici 10 arguments contre l’obligation de porter un casque à vélo.

Helmets helmets helmets | Forum | road.cc
The validity of any systematic review depends on the assiduousness with which the authors identify the existing published research. I'm not happy with this article for several reasons:

1) it was published in a paywalled venue, excluding the general public, and also many interested professionals should their institution not subscribe to the journal. Good science is open science. Hiding your results from public scrutiny, in this day and age, is simply not acceptable. Happily there is sci-hub.cc...

2) Even once the article is obtained, the methods section lacks a clear description of the inclusion and exclusion criteria, which can only be obtained by requesting the study protocol from the first author. As the flowchart in figure 1 (results) makes clear, their initial search yielded 2393 "records"; the exclusion of duplicates took this to 1215 records (fair enough), BUT then the records are "screened" excluding 1124 records to yield 91 articles that were actually analysed at full-text level and THEN another 48 excluded ("with reasons") to yield the 40 studies that were actually included in the final analysis.

This screening process is NOT published. As, obviously, the choice of which data to analyse are crucial to the eventual results obtained, I am not a happy reader at this point.

3) Perhaps less important, but both authors declare that they are affiliated to a department of maths and statistics. I'm quite old-fashioned, but I like to see at least one medical degree among the authors when they presume to declare expertise on categorising the character and severity of injuries--in other words to have some clue about how the data were actually generated in the first place. This is particularly important when like is being compared with quite like, but not exactly. The specialist actually qualified to do this is a public health physician or medical epidemiologist. Now it may be argued that as this article has passed muster in the peer review process of the International Journal of Epidemiology, then it is OK, but given the opacity of the methods, I think reasonable doubt opens up.

4) Finally, the authors are Australian, and seem to have a vested interest in promoting the lamentable compulsion policy there. In their discussion they say that "the results of this review do not support arguments against helmet legislation from an injury prevention perspective." But we're not just interested in injury prevention: we're interested in overall health, and a decline in cycling participation is very clearly a decline in overall public health.

So I have serious doubts about the validity of their message.

Study: The Latest Evidence That Bike Helmet Laws Don't Help Rider Safety - CityLab
The point is not that helmets do nothing or that you shouldn’t wear them. If you fall off your bike and hit your head, it’s obviously much better to have a helmet on. At a personal level, if that’s what it takes to get you riding, by all means, helmet up. But at the local government level, it’s time to recognize that other safety measures have far greater public health benefits—in particular, well-designed infrastructure that separates riders from general traffic.

[my comment: Helmet laws were always a victim-blaming distraction from the real issue of bad driving and disrespect for cyclists, so research results that discredit helmet compulsion as an effective public health measure are hardly surprising. Looks like it's time to jump ship and demand "better infrastructure," while ignoring, of course, the real problem: too many motor vehicles, negligently driven.
Vancouver? Illegal to even cycle two abreast there, I read. Mustn't delay the motorist for even a moment, must we? I do understand that as a major oil producing country, each new cyclist is bad news for your economy. Best put the cyclists off the road on to some annoying narrow cycle lanes with plenty of stop lines and long waits at tricky junctions. If you can ensure the cycle track surfacing is inferior, whilst banning cyclists from using the nice smooth direct road alongside, so much the better. Make sure you include plenty of car parking alongside so they'll get doored now and again. Do route cyclists up on to the sidewalk from time to time: it's an effective way of making cyclists more generally disliked by pedestrians, further diverting attention from the real problem.
Yes, more cycle infrastructure is certainly the answer: for committed Fordists.]

Bicycling injury hospitalisation rates in Canadian jurisdictions: analyses examining associations with helmet legislation and mode share -- Teschke et al. 5 (11) -- BMJ Open
The fact that we did not find an effect of helmet legislation for injuries to any body region is not surprising, since most injuries were not head injuries. Even studies of helmet use have not found an effect for serious injuries to any body region.48 After a crash, injuries to the torso, extremities and neck cannot be mitigated by a helmet, and injuries to these body regions were incurred in 87% of the hospitalisations in this study. The lack of a protective effect of legislation on brain and head injury rates is more unexpected. Helmet legislation in Canada has resulted in higher helmet use, so this cannot explain the results.

Il est maintenant admis que si les automobilistes portaient un casque, on pourrait sauver des centaines de vies par an, soit beaucoup plus que les cyclistes morts lors de leurs déplacements urbains. Pourquoi les constructeurs de voitures, les associations d’automobilistes ou les députés ne militent-ils pas pour le port du casque en voiture? J’ai ma petite idée, mais je vous laisse tirer vos propres conclusions…
