Some countries and lower jurisdictions have enacted laws or regulations which require cyclists to wear a helmet in certain circumstances, typically when riding on the road or a road-related area (such as a bicycle lane or path). In some places this requirement applies only to children under a certain age, while in others it applies to cyclists of all ages.
Research indicates that bicycle helmet laws reduce bicycle fatalities and injuries. [1] [2] Large increases in the rate of helmet wearing usually take place after helmet laws are passed. [3] [4] Evidence is mixed as to whether the helmet laws lead to less cycling. [1]
Modern varieties of bicycle helmet first became commercially successful from 1975. [5] Industry helmet standards were developed from the 1970s [6] and are still under development. [7] [8] Even before then, there had been calls for riders to wear helmets, [9] based on the assumptions of high risk to cyclists and effectiveness of helmets in preventing serious injury. [9]
The Royal Australasian College of Surgeons campaigned actively to raise public awareness, acceptance and demand, [10] and helmets first became compulsory across Australia from 1990 to 1992. [11] [12] In New Zealand, Rebecca Oaten was a prominent champion; after a disastrous head injury to her son in 1986 she traveled the country to push the importance of wearing helmets. For six years she visited an average of four schools a day. [13] [14] [15] [16] Bicycle helmets became compulsory in New Zealand in January 1994. [17] A report from the Australian Department of Transport in 1987 cast doubt on the effectiveness of helmets in real accidents. [18] In 2004 members of the UK Parliament questioned the claims made for helmets in an Early Day Motion. [19]
By 1991, after widespread well-resourced campaigns, [20] [21] the use of helmets had attained near-universal support in the United States, becoming what the League of American Wheelmen characterized as a "Mom and apple pie" issue. [22] Some official and professional bodies in the English-speaking world now support compulsory use of helmets. [23] [24] A 2009 poll of U.S. adults found that 86% supported helmet laws for children. [25] Support has spread elsewhere; Safe Kids Worldwide, which has received financial support from equipment suppliers including helmet manufacturer Bell Sports, was founded in 1987 and is currently active in a total of 17 countries. [26] Australia, Canada, the Czech Republic, Finland, Iceland, New Zealand, Sweden, and the United States have bicycle helmet laws, in at least one jurisdiction, either for minors only, or for all riders. Spain requires helmets to be worn while cycling along public roads outside population centers, except for riders with a medical exemption or on extremely hot days. [27]
Helmet laws are not universal in the United States; most U.S. states and municipalities have no laws or regulations regarding helmet use. In the U.S.A. 21 states and the District of Columbia have statewide mandatory helmet laws for children. [28] 29 U.S. states have no statewide law, and 13 of these states have no such laws in any lower-level jurisdiction either. [29] The territory of Guam made helmets compulsory for all bicycle riders and passengers on 27 February 2012. [30]
Israel's helmet law was never enforced or obeyed. A long and sophisticated volunteer campaign led to the revocation of the adult element, in order to allow bike-hiring schemes to work. [31] [32] An official predicted that this would have disastrous health consequences. [33] Mexico City has repealed its helmet law to allow a bike-sharing scheme to work. [32]
The mandatory wearing of helmets is frequently supported by medical organizations and by bodies responsible for road safety. [34]
Head injury can result in death or disastrous long-term physical and mental disability. Such injuries have happened to cyclists, and such cases have given powerful stimulus to political activity. [35] A helmet testing specialist states that some of these accidents can generate energy levels beyond those used when certifying competition motor racing helmets. [36] One study which examined post-mortem examinations of the twenty cyclist fatalities in Auckland, New Zealand between 1974 and 1984 found that sixteen died of fatal injury to multiple organ systems, including fourteen with fatal brain injuries; four died solely of brain trauma. [37]
A 2018 review analysed the results of 21 studies on the effects of bicycle helmet legislation. [1] The meta-analysis results showed that helmet legislation reduced total head injuries by 20%, and serious head injuries by 55%.
A motoring breakdown organization has sponsored an initiative by the Bicycle Helmet Initiative Trust which supports legislation, reporting that "in 2009/10 nearly 6,000 young cyclists were admitted to hospitals and of these 40% had suffered head injuries. Around 83% of young cyclists suffering head injuries were not involved in a collision with another vehicle but merely hit their head after falling from the cycle. " [38] [39] In North Carolina, where bicycle helmets are compulsory for children, the North Carolina Department of Transportation publish a fact sheet stating that a bicyclist is killed or injured approximately every six hours and that helmets reduce the risk of head injury by as much as 85% and the risk of brain injury by as much as 88%. [40] The National Highway Traffic Safety Administration reports that in 2006, 773 bicyclists were killed in the US. In a speech arguing for helmet legislation in the UK Parliament, an MP said: "In a three-year period from 2003, 17,786 children aged 14 and under were admitted to NHS hospitals in England because of injuries incurred while cycling" [41]
In the UK, some 8,000 years of average cycling will produce one clinically severe head injury, and 22,000 years one death. [42]
Ordinary cycling in the UK is not demonstrably more dangerous than walking or driving, and is far safer for other road users. [43]
Cases of head injury report a lower rate of helmet-wearing than controls who have injured other parts of the body. [44] This has been taken as strong evidence that cycle helmets are beneficial in a crash. The most widely quoted case-control study, by Thompson, Rivara, and Thompson, reported an 85% reduction in the risk of head injury by using a helmet. There are many criticisms of this study. [45]
Cycling organizations generally oppose laws mandating the wearing of helmets. [46] [47] Civil Liberties Australia published three articles indicating concerns at the consequences of having a mandatory requirement. [48] In Ontario Canada, opposition has been present for many years. [49]
A 2018 meta-analysis found that "effect of mandatory bicycle helmet legislation for all cyclists on head injuries is a statistically significant reduction by 20%... Larger effects were found for serious head injury... larger effects were found when legislation applies to all cyclists than when it applies to children only." [1] A 2017 systemic review and meta-analysis concluded, "Bicycle helmet use was associated with reduced odds of head injury, serious head injury, facial injury and fatal head injury. The reduction was greater for serious or fatal head injury." [50] A 2011 Cochrane review, concluded that "helmet legislation appears to be effective in increasing helmet use and reducing head injuries." [51] A 2008 Cochrane review concluded that "Bicycle helmet legislation appears to be effective in increasing helmet use and decreasing head injury rates in the populations for which it is implemented," but the study noted that very few high-quality studies existed at the time. [52]
A 2019 study found that bicycle helmet laws in Australia led to a substantial decline in bicycle-related fatalities. [53]
A 2006 BMJ study found that enforced helmet laws did not lead to a reduction in head injuries. [54] This study was the subject of vigorous debate. [55] [56] [57]
The most studied laws are in New Zealand and Australia. A study conducted by the University of New South Wales in 2011 concluded that Mandatory Helmet Laws led to a 29% reduction in cycling related head injuries. [59] A 2002 study of the New Zealand law found that the law had net positive effects on minors, but that the costs outweighed the benefits for adults. [60]
A 2019 systematic review found no evidence in most of the research literature that bicycle helmet led to more risky behavior by bicyclists. [61]
A 2018 meta-analysis concluded that the evidence was mixed as to whether bicycle helmet laws reduced cycling. [1] Regular moderate cycling is extremely beneficial for health, [62] [63] [64] [65] [66] [67] [68] [69] thus if mandatory helmet use deters cycling, the health impact could be unintentionally adverse.
A 2018 study found "that “all-age” bicycle helmet laws significantly increased both adult and youth helmet use by 50%–190% relative to pre-reform levels, with larger effects for younger adults and less-educated adults. All-age helmet laws had modest effects at reducing cycling and increasing in-home exercise during winter months among adults but did not meaningfully affect weight. Overall, our findings confirm that all-age helmet laws can be effective at increasing population helmet use without significant unintended adverse health consequences." [4]
A 2006 BMJ study showed that in states which had helmet laws, the amount of cycling to work had reduced by about one third. [54] Other evidence strongly suggests that promotion or compulsion of helmet use deters cycling. [70] [71] It has been suggested that this is irrelevant to health as "any cyclist who wants to exercise but hates helmets enough to quit cycling if a law is passed can turn to a multitude of other activities to stay active". [72] However, relatively few people who bicycle as part of their daily routine, would increase gym visits or take up other exercise activities if, as a result of a mandatory bicycle helmet law, they were discouraged from cycling. For many people, exercise is only sustainable if it is integrated into daily routine such as shopping errands or traveling to and from work. [73] Helmet laws seem to offer net health benefit only in dangerous bicycling environments under optimistic assumptions of the efficacy of helmets. [73]
A 2011 review commissioned by the Queensland Government found little evidence to support the claim that mandatory helmet usage discouraged bike riding. [59] However, the helmet laws are frequently suggested as the main cause of the disappointingly low usage of the bicycle-sharing systems in Melbourne and in Brisbane. [74] [75] In a 2012 study, 61% of the respondents identified helmet issues as the main reason preventing them from using the bike sharing system in Brisbane, most of this was the lack of helmet availability, the study revealed a dramatic increase in usage after the council made helmets available with the bicycles. [76]
Large increases in the rate of helmet wearing are usual after helmet laws. [3] [4] Not all laws have increased helmet use, no such increase was noted among the children covered by the North Carolina bicycle helmet law. [77] In another area, an early rise in helmet use was followed by a fall to below pre-law levels. [78] [79] Attitudes to cycling, and the amount of enforcement effort, may both be relevant. [80] A qualitative systematic review found that perceptions on helmet design, its quality and cost, perceived risk and benefits, parental strategies and adoption and enforcement of laws influencing helmet use. [81]
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
Cycling, also known as bicycling or biking, is the activity of riding a bicycle or other type of cycle. It encompasses the use of human-powered vehicles such as balance bikes, unicycles, tricycles, and quadricycles. Cycling is practised around the world for purposes including transport, recreation, exercise, and competitive sport.
A motorcycle helmet is a type of helmet used by motorcycle riders. Motorcycle helmets contribute to motorcycle safety by protecting the rider's head in the event of an impact. They reduce the risk of head injury by 69% and the risk of death by 42%. Their use is required by law in many countries. However, only 10.4% of all motorcyclists wear helmets, according to the World Health Organization in 2016.
High-visibility clothing, sometimes shortened to hi vis or hi viz, is any clothing worn that is highly luminescent in its natural matt property or a color that is easily discernible from any background. It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment. Many colors of high visibility vests are available, with yellow and orange being the most common examples. Colors other than yellow or orange may not provide adequate luminescence for conformity to standards such as ISO 20471.
Utility cycling encompasses any cycling done simply as a means of transport rather than as a sport or leisure activity. It is the original and most common type of cycling in the world. Cycling mobility is one of the various types of private transport and a major part of individual mobility.
Road cycling is the most widespread form of cycling in which cyclists ride on paved roadways. It includes recreational, racing, commuting, and utility cycling. As users of the road, road cyclists are generally expected to obey the same laws as motorists, however there are certain exceptions. While there are many types of bicycles that are used on the roads such as BMX, recumbents, racing, touring and utility bicycles, dedicated road bicycles have specific characteristics that make them ideal for the sport. Road bicycles generally have thinner tires, lighter frames with no suspension, and a set of drop handle bars to allow riders to get in a more aerodynamic position while cycling at higher speeds. On a flat road, an intermediate cyclist can average about 18 to 20 mph, while a professional rider can average up to 25 mph (40 km/h). At higher speeds, wind resistance becomes an important factor; aerodynamic road bikes have been developed over the years to ensure that as much as possible of the rider's energy is spent propelling the bike forward.
A bicycle helmet is a type of helmet designed to attenuate impacts to the head of a cyclist in collisions while minimizing side effects such as interference with peripheral vision.
Risk compensation is a theory which suggests that people typically adjust their behavior in response to perceived levels of risk, becoming more careful where they sense greater risk and less careful if they feel more protected. Although usually small in comparison to the fundamental benefits of safety interventions, it may result in a lower net benefit than expected or even higher risks.
Safety in numbers is the hypothesis that, by being part of a large physical group or mass, an individual is less likely to be the victim of a mishap, accident, attack, or other bad event. Some related theories also argue that mass behaviour can reduce accident risks, such as in traffic safety – in this case, the safety effect creates an actual reduction of danger, rather than just a redistribution over a larger group.
Cycling in Melbourne is an important mode of transport, fitness, sport and recreation in many parts of the city. After a period of significant decline through the mid to late 20th century, additional infrastructure investment, changing transport preferences and increasing congestion has resulted in a resurgence in the popularity of cycling for transport. This is assisted by Melbourne's natural characteristics of relatively flat topography and generally mild climate.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, which types of cycling environment or cycling infrastructure is safest for cyclists. The merits of obeying the traffic laws and using bicycle lighting at night are less controversial. Wearing a bicycle helmet may reduce the chance of head injury in the event of a crash.
A cycle track or cycleway (British) or bikeway, sometimes historically referred to as a sidepath, is a separate route for cycles and not motor vehicles. In some cases cycle tracks are also used by other users such as pedestrians and horse riders. A cycle track can be next to a normal road, and can either be a shared route with pedestrians or be made distinct from both the pavement and general roadway by vertical barriers or elevation differences.
A motorized scooter is a stand-up scooter powered by either a small internal combustion engine or electric hub motor in its front and/or rear wheel. Classified as a form of micromobility, they are generally designed with a large center deck on which the rider stands. The first motorized scooter was manufactured by Autoped in 1915.
Bicycle helmets have been mandatory for bicycle riders of all ages in New Zealand since January 1994.
Cycling in Australia is a common form of transport, recreation and sport. Many Australians enjoy cycling because it improves their health and reduces road congestion and air pollution. The government has encouraged more people to start, with several state advertising campaigns aimed at increasing safety for those who choose to ride. There is a common perception that riding is a dangerous activity. While it is safer to walk, cycling is a safer method of transport than driving. Cycling is less popular in Australia than in Europe, however cyclists make up one in forty road deaths and one in seven serious injuries.
Australia was the first country to make wearing bicycle helmets mandatory. The majority of early statistical data regarding the effectiveness of bicycle helmets originated from Australia. Their efficacy is still a matter of debate.
Laws concerning the wearing of bicycle helmets vary around the world,. Five countries currently both require and enforce universal use of helmets by cyclists. Partial rules apply in some other jurisdictions, such as only for children, in certain states or sub-national divisions, or under other limited conditions.
The requirement to wear bicycle helmetsin the United States varies by jurisdiction and by age of the cyclist, for example 21 states and the District of Columbia have statewide mandatory helmet laws for children. 29 US states have no statewide law, and 13 of these states have no such laws in any lower-level jurisdiction either.
Bicycle law is the parts of law that apply to the riding of bicycles.
There is debate over the safety implications of cycling infrastructure. Recent studies generally affirm that segregated cycle tracks have a better safety record between intersections than cycling on major roads in traffic. Furthermore, cycling infrastructure tends to lead to more people cycling. A higher modal share of people cycling is correlated with lower incidences of cyclist fatalities, leading to a "safety in numbers" effect though some contributors caution against this hypothesis. On the contrary, older studies tended to come to negative conclusions about mid-block cycle track safety.
The results of a comparative study of the injury profiles of Victorian motorcyclist and bicyclist casualties were used by the Royal Australasian College of Surgeons in initiating a state-wide campaign to promote the wearing of approved safety helmets by Victorian bicyclists and to obtain the necessary legislation whereby such wearing would become compulsory
...events have overtaken the League's initiatives on the helmet issue. Strong lobbying groups, including the American Academy of Pediatrics and the Safe Kids Coalition, have been promoting bills requiring children to wear helmets when riding as passengers on bicycles, and setting standards for child carriers. The child carrier industry has also played a part in drafting these bills. ...helmet laws may be unstoppable; helmets have become a "Mom and apple pie" issue, due to widespread publicity in the media...
