Under the laws of New York, all persons who ride a motorcycle must wear helmets that meet the federal requirement for motor vehicle safety. Data from years of study of motorcycle accidents show that head injury is one of the most common causes of serious injury and even death in motorcycle accidents in NYC. Wearing the right helmet can help prevent serious and fatal head injuries. Although over the years, compliance with the helmet law has improved considerably, there are still persons who continue to operate their motorcycle without wearing a helmet.
