Summary

  • There are 47 states with motorcycle helmet laws.
  • Seventeen states require helmets, regardless of the rider’s age.
  • Riding helmetless can reduce the value of your accident injury claim.

Unlike vehicle occupants in car accidents, motorcyclists have no passenger compartment to protect them in a crash. Operators and passengers reduce their risk of head injury in motorcycle accidents by up to 69% when they wear helmets. As a result, helmeted riders are less likely to suffer death or incapacitating injuries.

However, states question whether the government can require riders to wear helmets or if the risks and responsibilities of helmetless riding should fall on motorcyclists. This philosophy has won over legislatures in most states. As a result, motorcyclists will find wide variation in motorcycle helmet laws by state.

Origin of Motorcycle Helmet Laws

In 1966, Congress passed the Highway Safety Act (HSA) to address highway road deaths. The law required states to pass numerous safety laws, including motorcycle helmet laws. States that did not enact the laws would lose federal highway funding.

By 1975, 47 states and the District of Columbia had passed helmet laws. However, mandatory helmet laws were unpopular with motorcyclists, and the American Motorcycle Association (AMA) played a significant role in repealing these laws.

Motorcyclists took the matter to court, arguing that helmets were a personal choice that the government should not regulate. This argument was unsuccessful, as courts concluded that these safety matters fell under appropriate state policing power.

After some pressure, Congress removed the highway funding incentive in 1976. States persuaded by the personal choice arguments started repealing their helmet laws. By 1980, only 19 states and the District of Columbia had helmet laws.

States with Motorcycle Helmet Laws

Motorcycle helmets reduce motorcycle deaths, and helmet laws play a role. When Texas repealed its universal helmet law, helmet use dropped 30%, while fatalities jumped by 21%.

However, state helmet laws still vary in scope. Here is an overview of current state helmet laws.

Which States Can You Ride a Motorcycle Without a Helmet?

Only three states allow helmetless riders. Police cannot cite operators or passengers in the following states for riding without a helmet:

  • Illinois
  • Iowa
  • New Hampshire

Illinois and Iowa had universal helmet laws but repealed them in 1970 and 1976. New Hampshire, following its state motto of “live free or die,” has never had a motorcycle helmet law.

Which States Have Limited Motorcycle Helmet Laws?

A limited motorcycle helmet law restricts the requirement to an age group or circumstances. For example, a state may require helmet usage by all passengers and riders under 18.

The states that place an age requirement include:

State
Age Requirement
State
Age Requirement
Alaska
17 years of age and younger
Missouri
25 years of age and younger
Arizona
17 years of age and younger
Montana
17 years of age and younger
Arkansas
20 years of age and younger
Nebraska
20 years of age and younger
Colorado
17 years of age and younger, including passengers
New Mexico
17 years of age and younger
Connecticut
18 years of age and younger
North Dakota
17 years of age and younger
Delaware
17 years of age and younger, including passengers
Ohio
17 years of age and younger
Florida
20 years of age and younger
Oklahoma
17 years of age and younger
Hawaii

Pennsylvania

Idaho

Rhode Island
20 years of age and younger
Indiana

South Carolina

Kansas

South Dakota

Kentucky

Utah
20 years of age and younger
Michigan
20 years of age and younger
Wisconsin
17 years of age and younger
Minnesota
17 years of age and younger
Wyoming
17 years of age and younger

While these states may have reached a fair compromise between safety and freedom, these laws are often unenforceable. Officers cannot determine a rider's age from afar, so they may choose to save their time pulling over helmetless riders.

Other limited helmet laws do not depend on age. These include:

State

Alaska
All riders with instructional permits and their passengers must wear helmets, regardless of age
Delaware
Novice riders and their passengers must wear helmets for the first two years of the rider’s endorsement, regardless of age
Florida

Kentucky

Maine
Riders must wear helmets if they carry an instructional permit or have been licensed for less than one year Passengers must wear helmets if the rider requires them
Michigan
Riders and passengers without additional insurance must wear helmets, regardless of age
Missouri
Riders without medical insurance must wear a helmet
Ohio
Riders licensed for less than one year must wear a helmet, as well as their passengers
Pennsylvania
Riders licensed for under two years must wear a helmet unless they complete a PennDOT or Motorcycle Safety Foundation-approved safety course
Rhode Island
Riders licensed for less than one year must wear helmets, as must their passengers
Texas
Riders without a safety course certification or medical insurance must wear helmets
Wisconsin
Riders with instructional permits must wear helmets, regardless of age

What States Require Motorcycle Helmets for Everyone?

Only 17 states and Washington, D.C., have universal helmet laws, meaning everyone must wear one regardless of age. They include:

  • Alabama
  • California
  • District of Columbia
  • Georgia
  • Louisiana
  • Maryland
  • Massachusetts
  • Mississippi
  • Nevada
  • New Jersey
  • New York
  • North Carolina
  • Oregon
  • Tennessee
  • Vermont
  • Virginia
  • Washington
  • West Virginia

There may be exceptions to these laws based on vehicle type. However, those are limited to smaller, slower-moving vehicles. If you ride a fully-powered motorcycle, expect to wear a helmet on all public roads in these states.

How Helmet Use Affects Motorcycle Accident Claims

Riders who fail to wear helmets risk severe or fatal injuries. A reasonable motorcyclist knows these risks. Unfortunately, drivers involved in motorcycle crashes may argue helmetless riders bear the fault for their head injuries, even if they are at fault.

Personal injury law depends on a victim avoiding negligence. Some states hold a victim’s negligence, even if it's minimal, against them.

A few states use a contributory negligence standard. Under this legal principle, any negligence by the victim bars all injury compensation. A motorcyclist recovers nothing even if they bear only 1% of the fault and the other driver bears 99%.

Most states use “comparative negligence.” This legal theory is more forgiving of riders who choose not to wear helmets. Rather than barring all compensation, the law reduces their compensation in proportion to the rider’s share of the fault. So, a motorcycle rider who bears 22% of the fault will be compensated for 78% of the losses.
