The impact of compulsory cycle helmet legislation on cyclist head injuries
Date:6/22/2011

Bicycle-related head injuries fell significantly in the months after mandatory helmet legislation came into effect in NSW, and recent calls for a repeal of the laws should be rejected, new research based on hospital admissions data shows.

The injuries fell by up to 29% after the laws were introduced in 1991, according to the study by researchers at the University of New South Wales (UNSW) and the Sax Institute, published in the high impact journal Accident Analysis and Prevention.

"We set out to perform the most comprehensive analysis possible on the subject while addressing any data limitations and possible confounding factors," said study author Dr Jake Olivier.

"What we found provides compelling evidence that the legislation has served its purpose in reducing bike-related head injuries and any repeal of the laws would only put lives at risk," he said.

UNSW's Chair of Road Safety and study co-author Professor Raphael Grzebieta said the study backs up overwhelming evidence from biomechanical experiments and in-depth accident case analyses that helmets prevent head injury. "It shows what we've suspected for a long time that you would be unwise to 'hit the road' without a helmet," he said.

Australia was the first country to introduce mandatory helmet legislation in 1991, but 20 years later public debate about the legislation's effectiveness in preventing head injuries continues.

Last year, a Sydney University study found the laws had failed and should be repealed because compulsory helmet wearing could be a disincentive to cycling. The academic paper was later retracted due to serious data and arithmetic errors.

In the new UNSW study, researchers from the Injury Risk Management Research Centre and the Sax Institute examined trends in NSW hospital admissions for cyclists and pedestrians, comparing the rate of head injury relative to arm injury, and separately for head injury relative to leg i
