How to Wear Helmet Safely

We have compiled a list of tips for wearing a helmet safely:

Choose the Size

Measure the distance from the top of your ears to the back of your skull with a cloth tape measure, then multiply that number by two or three if you have a larger or smaller size head.

Attach the Cheek Pads

Push the rear tabs of the cheek pads back behind your ears and press the front of the pads firmly against your cheeks. There should be no gaps between your face and the pads. Straps should be snug but not tight. If you can fit more than two fingers between strap and chin, they are too loose.

Always wear a helmet with both cheek pads firmly attached. If you do not, you may not get adequate protection in a crash.

Adjust the Strap

Adjust the helmet to be firmly attached to your head, but it can still be removed easily. Once installed, the helmet should be snug yet comfortable. Suppose you have a small or narrow head, or your head size changes noticeably with different brands or styles of helmets. In that case, it is important to measure this dimension before ordering carefully.

Also, remember that helmets are often sized differently than shoes. Allowing for this discrepancy will help keep your helmet securely in place in a crash.

Use the Strap Retention System

Fasten the strap retainer at the back of the helmet. It is a small plastic device that locks over the buckle, preventing it from being accidentally unfastened. Strap retainers are critical for children’s helmets, often wiggled off during play or removed to make a fashion statement.

Keep in mind that they are not designed to hold your helmet on in an accident. If your helmet comes off, you must replace it immediately with another one for protection.

Check for Secure Fitting

Pull the helmet straight back and then forward to see if it moves. If it does, use a chin strap adjuster to tighten the helmet until it does not move. Buckle chin straps so that you can fit only one finger beneath them. Straps should be snug but not tight.

It is better to have your helmet a little bit too loose than too tight. Never leave your helmet on the ground with the chin straps undone. You don’t want to become a statistic.

Always wear a Helmet on Your Biking Trip

Helmets only work when you wear them! You should always wear a helmet, no matter how short or long the trip and no matter how good you think your riding skills are. Always wear a helmet before starting, and always buckle it before you start.

Remember that helmets will not protect you against every possible crash. The most important thing about helmets is that they protect the head against most crashes. Even minor crashes can cause a concussion or brain injury, so always wear a helmet.

Importance of Bike Helmet

  • There is a mountain bike helmet law in most states.
  • It is the driver’s responsibility to ensure all riders have helmets on.
  • It’s best to wear a helmet during cycling, whether it be on the road or off-road.
  • If you don’t wear a helmet, you can get hit in the head by another motor vehicle or another rider.
  • Most motor vehicle accidents happen when the driver is looking at something else. If you are wearing a helmet, chances are you will be in less physical pain than someone who is not.
  • This will help prevent serious injuries like brain damage, memory loss, and even death.
  • If you don’t wear a helmet, it can give other riders or drivers the wrong impression when you are on the road.
