Answer: D. Identify contact points to identify potential injuries.
Explanation: During vehicle collisions, it is important to first, verify the safety of the scene before entering. Depending on the type of crash there are several potential injuries related. Some of the relevant information about the crash is the type (frontal, lateral, from behind; car-car; car-bike/motorcycle; or car-pedestrian), if the passengers had the safety belt on or not (helmet in the case of bikers and additional safety equipment), if the airbags were released, and if there were any fatalities involved.
