Wearing a helmet while riding a motorcycle is universally required in a some states, and required in others.

For example, California requires its riders to have their helmets on while Texas compels riders 20 years old or younger to wear helmets.

If you do not have a helmet, it might be in your best interest to buy one now. Injuries happen 5 time more likely when you’re riding a motorcycle than when you’re in a passenger car.

For your utmost safety, never buy a used helmet. Although used helmets look like they’re still in good shape, you never know if it’s already been in an accident. Otherwise, it could compromise your safety.

If you already own a helmet, make sure it complies with your state’s safety codes and regulations. To get the most accurate and up-to-date information, get in touch with your local DMV. Different states follow different helmet safety standards but a helmet with a DOT-certified stamp is best.
