The most catastrophic motor-vehicle accident injuries often involve motorcycle accidents since a rider and passenger have no protection in a collision and are often ejected from their seats. Some of these injuries include the following:
Spinal injuries: Fractured vertebra, herniated discs, and nerve damage as well as paralysis can easily occur when a rider is thrown into a car, tree, barrier, or onto the roadway.
Traumatic brain injuries (TBI): Full-faced helmets can dramatically decrease head and face injuries, but many riders do not wear helmets or they wear one that just covers the top of their heads. Severe concussions, intracerebral hemorrhaging, and facial fractures are not uncommon. These can lead to significant cognitive impairments in speech, memory, coordination, learning, and behavior.
Internal injuries: Internal bleeding and injuries to vital organs can occur if protective clothing is not worn even in minor collisions.
Disfigurement: Many riders wear short-sleeved shirts, sneakers, and shorts in warm weather and risk permanent scarring and disfigurement from severe road burns and lacerations.
Fractured bones: Many motorcycle riders sustain fractured bones when involved in motorcycle crashes. Protective motorcycle gear can help reduce the risk of fractures.
