Final answer:
Motor vehicle accidents are not the most common injury in older adults; falls are the leading cause of injuries in this age group.
Step-by-step explanation:
The statement 'Motor vehicle accidents are the most common injury in older adults' is false. It is falls that are the most common cause of injury in older adults, not motor vehicle accidents. This is supported by data from the Centers for Disease Control and Prevention, which indicates that falls are a major cause of head injuries and these injuries are most common among the very young, adolescents, and the elderly. Motor vehicle accidents, while significant, are not the most common cause of injuries in older adults. However, motor vehicle accidents are the most common cause of head injuries among adolescents (15-19 years) and young children (0-4 years).
