What should be assessed first during a scene size-up at a motor vehicle crash?

• A. Victim’s injuries
• B. Emergency contacts
• C. Possible hazards to your safety
• D. Bystander's involvement

Answer: (C)

During a scene size-up at a motor vehicle crash, the first priority is to assess possible hazards to your safety. This step is critical because first responders must ensure that the scene is safe before attempting to provide assistance to victims. Hazards may include oncoming traffic, fire from the vehicles, spilled fuel, electrical hazards, or even unstable vehicles.

Recognizing these dangers is essential to prevent additional injuries to the responders or bystanders while trying to assist those involved in the crash. Once the scene is deemed safe, responders can then focus on other aspects such as assessing the victims' injuries or answering questions from bystanders.
