Wearing a helmet, according to the CDC, decreases the risk of a brain injury by 69 percent. Head traumas may kill in a variety of ways. Bleeding to the brain, a failed operation, and even depression and suicidal ideation as a result of a traumatic brain injury (TBI) can all be deadly. Other factors such as age, weight, experience, gender, alcohol use, and motorcycle type also play a role in mortality. The most common cause of death in motorcycle crashes is head trauma, followed by traffic accidents injuries overall. Motorcycle riders under the age of 45 are more likely to die in a crash than someone older than that due to other factors such as experience and body weight. Riders who wear helmets are less likely to suffer serious injuries or death in a crash. Riders should wear helmets for protection against fatal injuries caused by road hazards such as rocks, glass, and trees. Worn properly, helmets reduce the risk of suffering a severe brain injury when involved in a crash. However, not all types of helmets provide the same level of protection. A study conducted by the University of Michigan found that riders who wore full-face helmets were less likely to suffer non-fatal head injuries than those who used open-faced helmets. In conclusion, motorcyclists face an increased risk of death compared to drivers of other vehicles. Factors such as rider age, experience, and type of helmet worn influence the likelihood of dying in a crash.
