Different states in the US follow different motorcycle helmet laws that cater to their own residents and constituents. Motorcycle helmet law has been instituted to provide safety and protection to motorcycle riders from different states. But the helmet law being followed in one state may not be the same as those followed in another. There are even other states that do not have their own laws governing the proper use of motorcycle helmets. There are currently 4 states that do not have their own motorcycle helmet law. These are Colorado, Illinois, Iowa, and New Hampshire. Of the other 46 states, 20 of them follow full helmet law for all riders in their territory to follow. They are Alabama, California, Georgia, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Nebraska, Nevada, New Jersey, New York, North Carolina, Oregon, Tennessee, Vermont, Virginia, Washington and West Virginia. But each of these states’ motorcycle helmet laws may have differing definitions on what constitutes a safety helmet. In the other remaining states, 19 have helmet laws that exempt adult riders. These are usually those riders who are 18 years old and over. These are the states of Alaska, Arizona, Connecticut, Delaware, Hawaii, Idaho, Indiana, Kansas, Maine, Minnesota, Montana, New Mexico, North Dakota, Ohio, Oklahoma, South Dakota, Utah, Wisconsin and Wyoming. There are seven states that require adult bikers at the ages of 18 and 20 to still wear helmets while riding their motorcycles. These states are Arkansas, Florida, Kentucky, Pennsylvania, Rhode Island, South Carolina, and Texas. It is on these states that some bikers think that they are being discriminated upon because of the requirement for riders between 18 and 20 years old. But some motorcycle riders just would want to rid themselves of having to don their helmets while riding their motorcycles. But these riders should realize that helmets are there for their safety and protection. Many motorcycle accidents have lessened rider mortalities, thanks to the protection offered by motorcycle helmets. DOT approved motorcycle helmets can help protect your head, most especially your brain from life threatening injuries in case of accidents. Your head is one of the most important parts of your body to protect while on a motorcycle because it houses the fragile brain. Although your skull protects it, sudden jolts and stops can easily injure it. Such injuries can make your brain to swell due to internal bleeding and inflammation. And when it swells, it would not have enough space inside the skull for the extra volume and will bring more damage to some other very vital regions like the eyes.
