The Union Leader newspaper reports that the New Hampshire Senate voted 16-8 in favour of the law requiring all
bicycle riders younger than 16 to wear helmets.
Governor John Lynch said he will sign the bill, which the House passed, 202-165, in March.
Supporting the bill, Senator Robert Flanders said if cycle helmet compulsion spares one child, one family, the anguish of dealing with severe brain injury, "it will be the most important vote I cast in this Senate."
Senator David Gottesman said estimates are that medical costs run to $4.5m for a child who suffers a serious brain injury. Proponents of the bill did not extend this statistic to head injuries caused by means other than bicycle accidents.
