Everyone riding a bicycle-be it a child or an adult. Helmet should be worn mandatory regardless of the distance of the ride-whether it is short trip or longer one or just a casual one. Being safe should be our first priority and we should make sure we buy a proper certified helmet.
According to www.nhtsa.gov:
Step 1-Helmet should fit snuggly Step 2-Helmet should sit level on your head and one or two finger- width above your eyebrows.
Step 3-Adjust the slider on both straps to form a “V” shape under, and slightly in front of, the ears.
Step 4-Center the left buckle under the chin.
Step 5-Buckle your chin strap. Tighten the strap until it is snug, so that no more than one or two fingers fit under the strap.
Step 6-Check for a final fitting and make sure all the straps are properly buckled.
