Wear a helmet! It's the law!
In July 2003, the King County Board of Health extended the King County bike helmet regulation (PDF) to include Seattle. The new rule went into effect in August 2003 and requires that all bicyclists (regardless of age) must wear a helmet.
Bicyclists throughout the county can be cited for not wearing helmets. Avoid fines, fees, and injuries by wearing a bike helmet!
How to fit a helmet
A review of several published studies estimated that bike helmets provide a 63-88% reduction in the risk of head, brain, and severe brain injury for all ages of bicyclists.

In order for the bike helmet to protect you, it needs to fit properly.
- Make sure your helmet is the right size. Try on several helmets before buying one. The helmet should fit comfortably. If needed, use extra pads for a snug and secure fit.
- Make sure the straps fit around your ear and under your chin snugly. The straps should form a "V" under your ears. Leave enough room for one finger to fit between your chin and the strap.
- The helmet should rest flat on your head, not too far forwards or backwards. The helmet should rest low on the forehead, no more than two finger widths above the eyebrows.
- Look for the CPSC or SNELL certification sticker inside the helmet.
- Get a new helmet when you grow out of it or within 5 years, whichever comes first.
- Replace your helmet after a crash or if it is cracked.
