Debate continues, without consensus, on the results of mandatory helmet use in the country.

The law also requires helmet use by certain bicycle passengers.

It estimated that "each year more than 7,000 head injuries could be prevented or reduced in severity with helmet use."

The most heated controversy surrounds the topic of compulsory helmet use.

In another area, an early rise in helmet use was followed by a fall to below pre-law levels.

Groups in other sectors also advocate helmet use or laws.

The same report estimated that, at most, universal helmet use would save the lives of three children aged 0 to 15 each year.
