Definition
-speed
-angle of impact
-use of restraints
-airbag deployment
-condition of steering wheel and -windscreen
-amount of intrusion
-person ejected from vehicle
-any deceased at scene

Definition
-Head: contusions, lacerations, skull #'s, cerebral haemorrhage/contusion

-Chest: # ribs, # sternum, flail chest, pulmonary/myocardial contusion

-abdomen: ruptured hollow organs (bladder, stomach), ruptured solid organs (liver, spleen).

Definition
-person goes forwards then backwards- hyperextension of neck
Term
side impact potential/expected injuries
Definition
-car appears to move from under person
-person moves toward point of impact
-chest and hip hit door
-C-spine injury
-Head injury

vehicle rollover potential/expected injuries
Definition
-multiple impacts each time the vehicle roles

Definition
initial injuries from point of impact
spinal/head injuries

Definition
-Headon: rider goes over handlebars. Head and neck injuries. Direct contact with handlebars can cause pelvic, chest and abdo injuries
