Many motorcycle accidents on the road between passenger vehicles and motorcycles are the fault of the driver of the passenger vehicle. Even though it can be easy to show fault, knowing who was responsible won't heal injuries. There are some things motorcyclists do that can help prevent injuries. Helmets are one of those helpful tools that can prevent a collision from resulting in a fatality in some cases.
Arguably, one of the best pieces of safety equipment, a helmet can protect you if you're thrown from your bike. On top of that, the visor that is built in helps you see better, because it's tinted to avoid glare and to prevent wind and insects from getting in your eyes. Right now, only 19 states and Washington, D.C., require helmets across the board, and three states including Iowa, New Hampshire and Illinois have no helmet laws at all. While there is some appeal to the wind running through your hair and feeling closer to the elements, the right helmet can prepare you for the worst.
According to the National Highway and Traffic Safety Administration, those who ride motorcycles without helmets have a 40 percent higher likelihood of dying in an accident. Interestingly, when Louisiana introduced helmet laws, it saw a drop in motorcycle fatalities amounting to 30 percent in the first year.
Helmets are designed to prevent neck and head injuries, and sometimes, they can be the difference between a traumatic head injury and simply being knocked out. As a safety precaution, it's hailed as one of the best ways to prevent head and neck injuries and to keep riders safer during a collision.
