Helmets are just as important as safety belts and child safety seats. They must be used every time regardless of how long or short the trip is. When buying a helmet make sure it is certified. Look for the Snell Foundation or ANSI Z90.4 sticker. How to Fit a Helmet A helmet should fit snugly on the top of the head.
Most helmets come with adjustable padding to achieve the best fit.
The front of the helmet should be about two finger widths above the eyebrows. You should be able to fit one finger between the chin strap and under the chin. The best way to test if your helmet is fit right is to shake your head forward and back. The helmet should stay in place.
