Why Do Some States Require Seat Belts But Not Motorcycle Helmets?

Most states in the U.S. have seat belt laws of some kind. In fact, only one U.S. state doesn’t legally require adults to wear seat belts in moving cars; New Hampshire only enforces seat belt use for children. Along with protecting the person wearing a seat belt, these laws can also protect other occupants of the vehicle, and even individuals outside the vehicle. For example, in a crash, an unbelted occupant of a car may be more likely to be thrown from their seat in a manner that could result in injury to other parties. Yet, there are examples of states with seat belt laws that nevertheless don’t have equivalent motorcycle helmet laws. Given that motorcycle helmet laws and seat belt laws appear to serve similar purposes, you might naturally question the reason for this discrepancy.

Even states that do require some motorcycle riders to use helmets don’t necessarily require them for everyone on a motorcycle. Factors like a rider’s age, their experience level, and other such details may influence whether their state’s law requires them to wear a helmet while riding.

It’s worth understanding a critical point before diving into this topic: There’s no “official” answer to the question of why some states that enforce seat belt laws have comparatively lax motorcycle helmet laws. Because the laws vary from one state to another, the justifications for said laws will also vary. However, it’s still possible to determine a few believable explanations for why the laws sometimes seem at odds with one another.

There was a time when it would have been safe to assume all states in the U.S. would adopt and enforce similar motorcycle helmet laws. In 1967, the federal government introduced a policy that would prevent states that didn’t enact helmet safety laws from receiving certain highway safety funds. However, in 1976, Congress decided the federal government shouldn’t have the power to penalize individual states for not enacting motorcycle helmet laws. No longer having a key incentive to enforce motorcycle helmet safety, numerous states loosened their motorcycle helmet statutes.

In the 1990s, the federal government again attempted to establish policies that would tie some federal funds to state laws requiring motorcycle riders to wear helmets. As before, special interest groups successfully challenged these policies.

That’s an important detail. Research indicates that some states lack strict motorcycle helmet laws because lobbying groups, like the American Motorcycle Association, have historically waged campaigns arguing that nationwide motorcycle helmet laws infringe on constitutional rights. Essentially, their argument boils down to “I have the right to decide which steps I do and don’t take to protect my own safety.”

Why wouldn’t this argument also apply to seat belts? Although there are many nuances to account for, it’s important to remember that a seat belt theoretically protects more than just the person wearing it. Except in rare instances, that’s not typically the case with a motorcycle helmet.

Researchers who’ve studied the effects of motorcycle helmet laws on motorcyclist injury and fatality rates point out that some of the arguments made against motorcycle helmet laws are flawed. Yes, it’s true that someone not wearing their seat belt in a car during an accident may pose a greater immediate risk to others than a motorcyclist not wearing a helmet during a crash. However, this argument doesn’t factor in the long-term costs associated with failure to wear a motorcycle helmet.

Helmets are essential motorcycle gear, having been shown to guard against serious injury when wrecks occur. Per the research, when states loosen or do away with motorcycle helmet laws, severe injury and death rates among motorcyclists in those states increase. The victims themselves aren’t the only ones affected by these trends. Motorcycle accident victims who don’t wear helmets place a greater burden on healthcare resources than those who do take basic precautionary steps, causing taxpayers to feel the cost of their choices.

The fact that a state doesn’t require motorcycle riders and occupants to wear helmets doesn’t mean it’s wise to ride without one. The data is clear: Motorcycle helmets prevent major injuries and deaths. When riders elect not to wear them, they may not be the only ones paying the price. That said, not all motorcycle helmets are created equal. Riders should familiarize themselves with the various types of motorcycle helmets available to make sure they choose the right style for their needs.
