Policy Key Facts
- In the UK, the life years gained due to cycling’s health benefits outweigh the life-years lost through injuries by around 20:1. Mile for mile, the slim chances of being killed whilst cycling are about the same as those for walking, and on average, one cyclist is killed on Britain’s roads for every 29 million miles travelled by cycle.
- Enforced helmet laws have consistently caused substantial reductions in cycle use (e.g. 30-40% in Perth, Western Australia). They have also increased the proportion of the remaining cyclists who wear helmets, yet the safety of these cyclists has not improved relative to other road user groups (e.g. in New Zealand).
- Even if helmets could prevent all cyclist injuries (including non-head injuries), a UK helmet law would only have to reduce the level of cycle use by about 4.7% to shorten more lives through inactivity than helmets themselves could possible save.
- Standards only require cycle helmets to withstand the sort of impact that a rider is likely to suffer if they fall from their cycle from a stationary position (about 12 mph). They are not and cannot be designed to withstand impacts with faster-moving cars, let alone lorries.
- Cycling typically accounts for 7-8% of the head injuries for which children are admitted to English hospitals – just a quarter of these to parts of the head that a helmet might protect.
Cycling UK View
- Government and other bodies concerned with health or road safety should simply aim to encourage people to cycle, regardless of whether or not they choose to wear helmets when doing so.
- Enforced helmet laws cause deep and enduring reductions in cycle use, undermining its very substantial health and other benefits. Given that the risks of cycling are low – they are not greatly different from those of walking or other forms of active recreation – even a very small reduction in cycle use would be counter-productive to health and other public policy objectives, regardless of the effectiveness or otherwise of helmets. In practice, this disbenefit is potentially very substantial, not least because the deterrent effect is likely to be strongest among key target groups for physical activity promotion, e.g. women, teenagers, less well-off communities and ethnic minority groups.
- Cycle helmets have in any case not been shown to be an effective way to reduce cyclists’ injury risks. Indeed they might even be counter-productive, by encouraging drivers or cyclists to behave less cautiously, and/or by increasing the risks of neck and other injuries. By deterring people from cycling, they may also reduce the benefits that cyclists gain from ‘safety in numbers’.
- Enforcing helmet laws would require levels of police activity that would be grossly disproportionate to any possible benefits. Conversely, unenforced helmet laws make no long-term difference to helmet use, and therefore cannot provide benefits in any case.
- Road safety policies should prioritise measures that reduce the risks that deter people from cycling – traffic speeds, hostile roads and junctions, dangerous or irresponsible driving, and lorries – and offering high quality cycle training for people of all ages, to give them the confidence and skills to ride safely on the roads.
- Individuals should be free to make their own decisions about whether or not to wear helmets, with parents making these decisions in the case of younger children. Their decisions should be informed by clear information about the uncertainties over the benefits or otherwise of helmets.
- Cycling UK supports politicians, celebrities and other role-models who choose to cycle uh-helmeted. Far from “acting irresponsibly”, they help to boost the perception of cycling as a normal, safe, aspirational and stylish activity that anyone can do in whatever clothes they normally be wear.
- Schools, employers and the organisers of non-sporting cycling events (e.g. sponsored rides) should not impose helmet rules for their pupils, staff and participants respectively. These rules are not justified in terms of health and safety, they are likely to reduce both the numbers and the diversity of people who take part in cycling, and they may in some circumstances be illegal.
- There is limited evidence on the risks involved in different types of off-road recreational cycling (from family riding to downhill mountain biking etc) and cycle sport. Likewise, evidence on the potential for helmet use to mitigate (or exacerbate) these risks is equally limited. These are in any case not matters for road safety policy.
- For sporting events, Cycling UK recognises the right of governing bodies to require the wearing of helmets in line with their own and international regulations for these events, given the different types of risk to which sport cyclists are exposed.
