Although biker helmet laws and fines vary between jurisdictions, it won't take too many checks made payable to state courts to hammer home the importance of wearing a helmet, if only for financial reasons.
Head injuries are the leading cause of motorcycle-related fatalities, according to the National Highway Traffic Safety Administration (NHTSA), and bikers who don't wear a helmet are about 40 percent less likely to survive an accident.
A motorcycle helmet protects your head and face from rocks, rubber from blown tires, garbage discarded from moving vehicles and other road debris.
A helmet is the best hat a biker can wear in the cold and rain. Vents provide airflow in the warmer months.
Motorcycle helmet visors keep the wind out of your eyes, improving your visibility and reaction time. Visors also protect against debris and can shade your eyes from bright sunlight, or oncoming headlights at night.
Wearing a helmet allows bikers to communicate with a passenger or other riders using headsets. You can warn others of dangers ahead or communicate your intentions when moving at high speed.
