Always wear your helmet, and always wear it correctly.
Here is the correct way to wear a helmet:
1. Eyes: Make sure your helmet is tilted forward in the front. You should see the bottom rim of your helmet when you look up.
2. Ears: The side straps of your helmet should form a 'V' under your ears. They should feel a little tight, but still remain comfortable.
3. Mouth: Make sure your chin strap is tight by opening your mouth as wide as you can. If your helmet hugs your head, it is tight enough.
