Since 1975, more than 100,000 motorcycle riders in America have died in crashes. The majority of states required motorcycle helmets in 1975, but today, only 20 states have universal helmet laws that require all riders to wear helmets, 26 states have partial coverage laws (usually only for young riders), and four states have no helmet laws.

Fewer than half of U.S. states require every motorcycle rider — drivers and passengers — to wear a helmet; and four states have no helmet requirements whatsoever. Around the world, the same patchwork legal pattern exists.

The AANS offers this advice for winter sports enthusuasts: Whether you are a novice or advanced, an average person or a celebrity – proceed with caution, and play it safe on the slopes and snow. Wearing a helmet and following other safety precautions may save your life or the life of your child.
