Motorcycle Helmet Ratings

When you’re shopping for a motorcycle helmet, you should make sure to purchase one that has been rated by a recognized safety organization.

Motorcycle helmet safety ratings include:

  • DOT (US Department of Transportation).
  • ECE (Economic Commission for Europe).
  • SNELL

DOT Helmet Sticker

In the United States, all legally accepted motorcycle helmets will include a DOT sticker or logo near the back of it.

The official DOT sticker ensures that the helmet meets a minimum safety standard based on a number of tests and criteria.

DOT approved helmets feature:

  • Inner liners that are at least 1″ thick.
  • Overall weight of about 3 pounds.
  • Sturdy D-rings and chinstrap to keep the helmet on securely.

Why Wear a Motorcycle Helmet?

It’s been proven that helmets save lives and prevent traumatic brain injury in the event of a motorcycle collision.

Head injuries are the most common cause of motorcycle fatalities. If you ride without a helmet and are involved in a crash, your chances of dying are much greater.

Motorcycle helmets are designed to reduce injury in the event of an impact. Through a combination of an outer shell, foam liner, padding system, and retention system a helmet works to absorb impacts so that your skull and brain do not.

While your helmet is designed to protect your head during a crash, it’s best if it never has to do so. Motorcycle helmets have other benefits as well, including:

  • Built in eye protection and face shields on certain types of helmets.
  • Protection from bugs, rocks, and road debris.
  • Reducing the harmful and exhausting effects of wind and road noise.
  • Helping make the rider more visible to other road users, depending on the color, reflectivity, and type.

How Does a Motorcycle Helmet Work?

Motorcycle helmets consist of 4 main components:

  • Hard outer shell: designed to compress and disperse energy during an impact.
  • Impact-absorbing liner: designed to further absorb shock and protect your head as it continues to move during an impact.
  • Inner padding: designed to keep the helmet comfortable, snug, and fitting effectively.
  • Retention strap: consisting of a chin strap that is designed to keep the helmet in place during a crash.

Helmets are designed to withstand a single impact.

When to Get a New Helmet

Motorcycle helmets are single-use, meaning they are designed to absorb a single impact.

If your helmet has been in a crash, if something hit it, or if it has been dropped, it’s time to replace it.

The materials that make up the impact-absorbing, retention straps, and padding can tend to wear and degrade over time. If your helmet is old or your notice signs of wear, you should also replace it.

In most cases, you should be replacing your helmet every 5 years.

Helmet technology only continue to improve, and motorcycle helmets are much lighter and more protective now than they were in the past.

If you’re unsure about your current helmet or find it uncomfortable, it’s probably time for a new one.
