Motorcycle helmet laws vary widely across the United States. Understanding these rules helps riders stay safe and avoid fines or license suspensions. In many parts of the world, helmets are mandatory for all riders, but in others they are required only for certain groups or not at all.
Universal helmet laws: In 2025, nineteen states and the District of Columbia have universal helmet laws that apply to every rider and passenger. These comprehensive laws aim to reduce head injuries and fatalities on the road.
Partial or age‑based laws: Twenty‑eight states enforce partial helmet laws. These typically require helmets for riders under a certain age (often 18 or 21) or for new riders who hold learner’s permits. Some states allow riders to forgo helmets if they meet insurance or training requirements. It’s important to check the specific rules in your state or any state you plan to ride through.
No helmet laws: Only three states—Illinois, Iowa and New Hampshire—currently have no motorcycle helmet laws. Even in these jurisdictions, wearing a quality helmet is strongly recommended for your safety.
New developments in 2025: This year has seen notable changes in helmet regulations. For example, Connecticut expanded its helmet requirement, raising the minimum age from 18 to 21 for motorcycle riders and passengers. The state also clarified how high‑powered e‑bikes are classified and mandated helmets for all e‑bike riders. Similar initiatives are being considered in other states as legislators respond to the rise of electric bikes and scooters.
Regardless of the legal minimums where you ride, the safest practice is to wear a certified helmet every time you get on a motorcycle or e‑bike. A well‑fitted helmet can make the difference between a minor incident and a life‑changing injury. Take a moment to learn your state’s regulations, but make safety your top priority by choosing to ride with a helmet everywhere you go.
