Rear end crashes Flashcards
What type of injuries are commonly caused by rear-end impacts?
Whiplash injuries
Whiplash injuries occur when the head and neck are not properly restrained during impact.
What happens to the passenger’s body during a rear-end collision?
The passenger’s body and torso move forward while the head and neck are left behind
This occurs because the head is relatively heavy.
What is the result of the passenger’s head being unrestrained during a crash?
The head and neck appear to be whipped back relative to the torso
This motion can lead to injuries in the cervical spine.
What may happen to an unrestrained passenger as the vehicle comes to rest?
The unrestrained passenger moves forward and strikes the dashboard
This can cause injury to the cervical spine and surrounding areas.
How does the cervical spine tolerate damage during a crash?
It is less tolerant of damage when bent back
This position increases the risk of injury.
What role do headrests play during a crash?
Headrests decrease extension of the head and neck
This helps to reduce the risk of injury.
Which other parts of the body may be at risk for injury during a rear-end impact?
Other parts of the spine and the pelvis
These body areas can also sustain injuries during such impacts.
What type of brain injury can occur from a rear-end collision?
Acceleration injury to the brain
This injury is referred to as the third collision of the brain within the skull.
What risk do backseat passengers wearing only a lap belt face during a rear-end collision?
Higher incidence of injuries to the thoracic and lumbar spine
Lap belts do not provide adequate restraint compared to shoulder belts.
