It also found that, while ''"children do have substantial protection from impacts to the head when wearing a bicycle helmet, it is likely that substantial head deformation occurs in a major impact due to the stiffness of the bicycle helmet liner in the Australian Standard bicycle helmet."''

| A 1993 study by Finch et al. analysed the results of surveys carried out in May 1990, 1991 and 1992 at 64 sites in metropolitan Melbourne. | |||
| Overall, 3121 cyclists were observed in 1990. In 1991, 1110 (36%) fewer cyclists were counted, compared to an increase of 293 cyclists wearing helmets. Although surveys conducted on weekdays had similar weather, there appears to have been some differences for counts conducted on weekends. About 32% of weekend observations in the pre-law survey were affected by rain, compared with about half in 1991 but only 14% in 1992. Counts in 1992 were also inflated by a bicycle rally passing through one of the sites in 1992.

| Compared to April 1991 (6072 child cyclists counted), the reduction in children's cycling the first year of the helmet law (April 1992) was 36%, with almost identical reductions in rural NSW (35%) and the Sydney metropolitan area (37%). In April 1993, the NSW surveys counted 3414 child cyclists, 44% fewer than the pre-law survey in April 1991.<ref name=RobinsonDL1996 /> Because cycling participation is weather dependent (fewer cyclists ride when it is raining, uncomfortably cold or hot, or very windy), and may also vary with holiday periods, surveys taken at different times of year, or in different weather conditions, may be subject to statistical ], and care should be taken when interpreting results. In NSW, the only pre-law data for adults at road sites was in September 1990 (with overcast weather conditions for Sydney) and at a different time of year to the post-law surveys. In the first post-law Sydney survey, in April 1991 (with sunny conditions), 22% more adult cyclists were counted than in the pre-law survey. In the second Sydney post-law survey, in April 1992, 2% more adult cyclists were counted than in the pre-law survey. In 1993 5% fewer were counted than in the pre-law survey. For road sites in regional areas adults counted reduced by 9% in 1991 and by 37% in 1993. In 1993 the weather was variable, with the threat of rain, across NSW on all survey days, with rain at one of the rural sites on 2 of these 3 days.<ref name=WalkerMB1990 /><ref name="WalkerMB1991"/><ref name=Smith&Milthorpe1993 /> In 1996, Walker reported the results of a consistent series of counts (adults and children) at the same 25 sites and observation times in Sydney.

| ==Effects of the law on helmet wearing rates== | |||
| In 1994 Marshall and White reported on the effects of bicycle helmet legislation in South Australia and stated that “...due to the disparate nature of the results from different sources, it is not possible to be conclusive about the effect of the requirement to wear bicycle helmets on the number of cyclists". City of Adelaide cordon counts of cyclists recorded very similar results for the years 1985 through to 1992 (except for 1988 which was attributed to changed survey methods for that particular year). The counts for 1993 showed a 15 per cent drop in cyclist numbers, though the authors attributed this to poor weather and street closures due to the impending Grand Prix car race in the city. They also examined South Australian household health survey data for 1990 and 1993 (about 3000 people in each survey) and found no statistically significant evidence of a change in cycling participation in any age group after the helmet law introduction, except for a decrease in females aged less than 15 years riding to school. However, the authors noted that surveys of helmet wearing in school children by Harrison Market Research showed a 38 per cent decline in cycling from September 1988 to March 1994, although they also note that cycling to school represented only 20% of cycling participation in under 15 year olds at that time. Helmet wearing rates increased substantially after the introduction of helmet legislation, with rates of wearing over 90% in cyclists aged 15 years or older, and rates up to 86% in school children. The helmet wearing rate in commuter cyclists observed in the cordon counts was 98%.<ref name=Marshall-and-White-1994>{{cite book|title=Evaluation of the compulsory helmet wearing legislation for bicyclists in South Australia.

| Hospital admission data in a 1995 Victorian study by Carr ''et al.'' showed that in the 3 after the helmet law, compared to the 3 years before the helmet law, pedestrian head injury hospital admissions dropped by about 20%, cyclist non-head injury admisions dropped by about 25%, cyclist head injury admissions dropped by 40%, and serious and severe cyclist head/brain injury (AIS 3/4) admissions dropped by 60%. After taking into account various factors that could have contributed to the reduction in cyclist head injuries, Carr ''et al.'' concluded that "the major part of this reduction is attributable to the introduction of the helmet wearing law" and that "This analysis has confirmed the substantial reductions being made in both number and severity of bicycle injuries since the introduction of the mandatory helmet wearing law". <ref>Evaluation of the bicycle helmet law in Victoria during its first four years; Carr D, Skalova M, Cameron M.; Monash University Accident Research Centre, 1995.</ref> | |||

| A 1995 SA study by Marshall and White found that, after accounting for exposure and changing hospital admission policy (for concussion injury), comparing the year before the helmet law to the year after the helmet law, the helmet legislation could be linked to a 12% reduction in cyclists injuries that were potentially preventable by the use of a helmet. Comparing the 2 years before and after the helmet law, Marshall and White found that the helmet law was responsible for a 25% decrease in hospital admissions for potentially preventable cyclist head injuries in SA.<ref name=Marshall-and-White-1994>{{cite book|title=Evaluation of the compulsory helmet wearing legislation for bicyclists in South Australia.

| In a 1996 analysis of cyclist and pedestrian casualties in Victoria and NSW, all-age cyclist counts in Victoria, and child cyclist counts in NSW, Dorothy Robinson noted similar declining trends for both cyclist and pedestrian head injuries in those states, and concluded that the decreases in hospital admissions were less than the decreases in cycling.<ref name="RobinsonDL1996"/> | |||

| A 1996 analysis by Bruce Robinson used information on head injuries, recorded for hospital admissions in Western Australia (WA) since 1971, to show the remarkably similar trends for all road users, and noted that a divergence between the injury rates from 1991 was unexplained, suggesting that it might just be random variation.<ref name=BruceRobinson-VeloAustralis1996>Is There Any Reliable Evidence That Australian Helmet Legislation Works?

The model showed that the divergence was not due to random variation (p<0.001); that before the helmet law the proportion of cyclists with a head injury was on average 6% higher than the proportion of pedestrians with a head injury; and that after the law the proportion of cyclists with a head injury was on average 16% lower than the proportion of pedestrians with a head injury. (This divergence can be seen on the graph, where the green/pedestrian line crosses the black/cyclist line the year before the helmet law is introduced.)

A noticeable feature in the details was for the ages, 55% of non-wearers were in the 0-19 age group compared with 19% for wearers. Bambach Table 2 shows 267 head injuries for non-wearers and 372 head injuries for wearers. There were 120 non-wearers over the 0.05 BAC limit and 85 wearers. Non-helmeted cyclists were more likely to display imprudent cycling behaviour, including disobeying a traffic control (9.4% compared with 3.3%) and cycling with a BAC greater than 0.05 (7.2% compared with 1.7%) (Table 2). However, non-helmeted cyclists were more likely cycling on the footpath (34.4% compared with 12.9%) and in speed zones of 50 km/h or less (56.9% compared with 50.0%), and less likely cycling on highways or freeways (8.3% compared with 12.6%). Overall, non-helmeted cyclists were more likely to be seriously injured in body regions other than the head (9.5% compared with 7.3%). | |||

| The Australian census asks about about method of travel to work on census day. Some states — Victoria, New South Wales and Tasmania — made bicycle helmets compulsory some months before the 1991 census. The trend{{clarify|reason=what trend?|date=June 2013}} from 1986-91 in all these states was below that from 1981-86. In SA the law was introduced a month before before the census and there was a greater reduction in cycling to work from the 1991 to the 1996 census than from 1986-91. In WA, the law was introduced on 1 Jan 1992 and enforced from 1 July 1992. In Qld, no provision was made for penalties and the law was widely ignored (about 50% of adults wore helmets) until 1 Jan 1993, when penalties were introduced. The greatest declines in cycling to work in these states were seen from the 1991 to 1996 census. In the Australian Capital Territory, cycling continued to increase despite the helmet law.<ref name=BHRF-ChangesCycleUseAustralia>{{cite web|title=Changes in cycle use in Australia|url=http://www.cyclehelmets.org/1194.html|author=Bicycle Helmet Research Foundation (BHRF)}}</ref> | |||

| ===Bicycle usage: states with and without enforced laws at the 1991 census=== | |||
| Aggregating all data for states with (Vic, Tas and NSW) or that may have had (SA) enforced helmet laws, and those that did not (Qld, WA and ACT) provides a clearer picture for the country as a whole. Both in capital cities and regional areas, cycling continued to increase on average in states without enforced helmet laws at the 1991 census. In contrast, the percentage cycling to work in states with enforced helmet laws decreased.<ref name=BHRF-ChangesCycleUseAustralia /> Before helmet legislation in 1986, capital cities had similar numbers (43,218 vs 40,798 in regional/rural areas) cycling to work but much lower percentages (1.14% compared to 3.14%). Capital cities generally have higher traffic levels and the lower percentages cycling to work suggest they were less conducive to cycling than regional areas such as small country towns, with less traffic and shorter distances between home and work. In Vic, NSW, Tas and SA, the fall in non-capital cities was from 2.9% in 1986 to 2.0% in 1991. Excluding the capital cities of Perth and Brisbane, in 1991, in Qld and WA, 3.57% of journeys to work were by bicycle. This fell to 2.45% by the 1996 census when these areas had enforced helmet laws, with continued declines to 1.7% by the 2006 census. Bicycle usage in all capital cites was 1.14% in 1986 when no helmet laws existed. In 1991, it was 0.99% in Victoria, NSW, Tasmania and SA — states that had (or for SA may have had) enforced laws — and 1.57% in Qld, ACT and WA. From 1986-1996, cycling to work in capital cities dropped from 1.14% to 0.89%, (a difference of 0.25 percentage points, but a decrease of 22%). Census data for Adelaide for 1986, 1991 and 1996 have commuter cycling counts on Census day of 8061, 7186 and 4494 respectively and represent a reduction from 1986 to 1996 of 44%.<ref>Travel to work in Australian capital cities, 1976-2006: an analysis of census data.

There was, however, the occasional pro-helmet advocate. The magazine editorial approach tended to be antagonistic toward compulsory helmet legislation, but some, e.g., Bicycle Victoria, encouraged helmet wearing. Articles within the body of the magazines, although primarily against the idea of bicycle helmet legislation, did proyide a more balanced perspective on the topic. Bicycle user groups throughout Australia supported helmet usage, although there were some concerns with helmet design, e.g., in the Northern Territory, the lack of air flow through helmets was of particular concern. The RTA's Bicycle Advisory Council also supported the legislation.</blockquote> | |||

| "Helmets and social equity — It is believed widely that bicycle helmets reduce the risk of brain damage in bicycle crashes. The data, however, is very thin even now, and was skeletal at the time of mandation of helmet use. Bruce Robinson and Dorre Robinson have both presented good analyses of these issues and will be familiar to most readers from the Velo Australis conference of 1996. A key problem is the use of limited data on head injury to infer data on brain damage - the real issue of concern. The two parameters are far less-well correlated than is believed widely, and Dorre Robinson’s 1996 paper is a good analysis of that. On the scant evidence available, helmet use should never have been mandated. Another issue that raised far too little concern at the time, though, was that of social equity." | |||

The same months in the post law years 1992-94 recorded 13067, 12470 and 10701 cyclist movements per week, reductions of 20%, 24% and 34% on pre-law cycling.<ref name=RobinsonDL1996 /> A telephone survey in which adults responded on behalf of themselves and their children found 13% of Perth and 8% of country cyclists had given up or cycled less because of the law. However, when the adult respondents in the telephone survey replied for themselves an estimated 27% of the State's adult population - cyclists and non cyclists - (the equivalent of 64% of current adult cyclists) would cycle more if not legally required to wear a helmet.<ref name=RobinsonDL1996 /> | |||
| Before the helmet law cycling was in increasing in WA, e.g. an increase from 220,000 regular cyclists in 1982 to 300,000 in 1986 and 400,000 in 1989. Census show cycling to work increased from 1.5% in 1981 to 1.7% in 1986 to 1.9% in 1991, falling to a much lower rate 1.2% in 1996. Travel surveys showed a 33% decline in cycling to work from 1986 to 2006 (from about 1.5 to 1.0 trips per weekday per 100 people), consistent with the census data. Shopping trips fell by 55%, from about 5.2 to 2.3 per weekday per 100 people; trips for education by 79%, from about 8.2 to 1.7 per weekday per 100 people.<ref>Ian Ker, 2011.

| Census data also shows that between 1986 and 2006, in Perth train travel to work more than doubled (from 2.2% to 5.1%), and travel to work by bus in Perth decreased by almost 50% (from 8.6% to 5.3%). | |||
| Regular telephone surveys conducted by the South Australian Health Commission reported a decrease in the proportion of people aged 15 years and over who cycled at least once a week from 12% to 10.4%, but no change in the frequency of at least weekly cycling for younger people (61%).<ref name=Marshall-and-White-1994 /> | |||
| However, from 1988 to 1994, cycling to school (which comprises about 20% of trips for children under 15) declined by 38.1%.

Revision as of 22:07, 11 June 2013

Between 1990 and 1992, Australian states introduced laws requiring people riding bicycles to wear bicycle helmets. Australia was the first country to do this, and much of the evidence on the effects of mass helmet use comes from Australia. Debate continues, without consensus, on whether helmet compulsion has resulted in a measurable reduction of head injuries or significant reductions of the amount of cycling.
History: lead-up to the laws
Modern varieties of bicycle helmet first became commercially successful from 1975. Industry helmet standards were developed from the 1970s and are still under development.
The Royal Australasian College of Surgeons took an early lead in gaining public awareness, acceptance, and demand for helmet compulsion. In 1978, the RACS's spokesman "We could perhaps worry a little less about and take a little less time in proving what is precisely right according to all standards … As doctors we are impatient. We cannot wait for 2 or 3 years’ evaluation." The RACS had been influential in bringing compulsory seat belts and motorcycle helmets and urged a bicycle helmet law as the "third major step" RACS members published in medical journals in support of helmet use by cyclists. Some of the arguments used have been disputed.
Empirical studies on injured cyclists in relation to the use of helmets were published from the late 1980s, some in Australia, both before and after helmet legislation. These consistently show that injured cyclists who had head injuries were less likely to report helmet use than those with injuries to other parts of the body.
The 1978 inquiry issued a final report in 1985. It recommended that cooperation of states and territories should be sought to "review the benefits of bicycle helmet wearing … and unless there are persuasive arguments to the contrary introduce compulsory wearing of helmets by cyclists on roads and other public places". A federal parliament committee was set up in 1985. Early in the course of its inquiry (before it had reviewed all the evidence), it said: "It is, of course, this Committee’s belief that all cyclists should wear a helmet to increase cycling safety."
A report from the Australian Department of Transport in 1987 examined cycling accident victims and found that "of the unhelmeted cases involving severe head injury, over 40 percent would definitely have had an improved outcome if a substantial bicycle helmet had been worn". It also found that, while "children do have substantial protection from impacts to the head when wearing a bicycle helmet, it is likely that substantial head deformation occurs in a major impact due to the stiffness of the bicycle helmet liner in the Australian Standard bicycle helmet." It recommended changes to the standards, in particular softer foam, which were not implemented.
In 1987 the Victorian Parliamentary Road Safety Committee tabled a report in the Parliament of Victoria which included a recommendation for mandatory wearing of helmets.
Meanwhile, in the late 1980s, cyclists in Australia experienced increased safety, associated with an increase in cycling though cycling still accounted for less than 2% of all journeys. Helmets were worn by a large minority of cyclists. In 1987, a majority of children aged five to seven years were in favour of wearing helmets, whereas older children were opposed.
By 1989, just before the government decided to introduce compulsory wearing of bicycle helmets, an officially commissioned survey showed that public support for it was 92% for children and 83% for all riders. The RACS used this study to push for mandatory bicycle helmets in Victoria. Opposition was fragmented and ineffective; no major cycling groups opposed the law in public.
Legal requirements and their results
The current legally required standard for a bicycle helmet is AS/NZS 2063. The law is laid out in Part 15 of the Australian Road Rules, approved by the Australian Transport Council. It specifies that "The rider of a bicycle must wear an approved bicycle helmet securely fitted and fastened on the rider’s head, unless the rider is exempt from wearing a bicycle helmet under another law of this jurisdiction." The law also requires helmet use by certain bicycle passengers.
Compulsory helmets were first introduced in Victoria in July 1990, followed in January 1991 by laws for adult cyclists in New South Wales and all cyclists in Tasmania, then in July 1991 for child cyclists in New South Wales and all cyclists in South Australia as well as Queensland, where the law was not enforced until 1 January 1993. In January 1992 helmet laws were introduced in the Northern Territory and Western Australia (not enforced first 6 months) and in July 1992 in the ACT. In Tasmania the law only applies on public streets, while in the NT since March 1994 there is an exemption for adults cycling along footpaths or on cycle paths.
Effects of the law on helmet wearing rates
Helmet wearing rates increased substantially after the introduction of helmet legislation, with rates of wearing over 90% in cyclists aged 15 years or older, and rates up to 86% in school children.
Cycling participation in relation to helmet laws
There is an ongoing debate about possible effects of the helmet laws on cycling participation. The Australian Transport Safety Bureau suggests that the risks of cycling have to be weighed against the substantial benefits.
A significant minority of both adults and children in Australia report that helmet laws are a disincentive to cycling.
Melbourne inaugurated a bicycle sharing system in 2010. The helmet law has been cited as one reason for its low initial usage.
Head injury rates in relation to helmet laws
There is extensive and ongoing debate about whether changes in head injury rates in Australia should be attributed to helmet laws. .
There is further ongoing discussion about whether safety per journey has been made better or worse for cyclists by the law.
Reception of helmet compulsion
In Victoria more than 19,000 fines for not wearing a helmet were issued in the first 12 months of their helmet law. Per kilometre, bicycle offence notices were about four times higher than all motor traffic offences put together. In 2005 almost 10,000 cyclists in NSW were fined for not wearing a helmet.
An overwhelming majority of the Australian public supports helmet laws. The RACS has maintained its support for compulsory helmets. There have been suggestions that enforcement of the law is insufficient.
Among a small minority of the Australian public, helmet laws are reported to be a disincentive to cycling.
The Queensland government announced in April 2013 that exemptions on religious grounds from mandatory bicycle helmet laws would be granted from 2014.
Opposition and deliberate disobedience to the law continue on a small scale.
