Which term describes the first contact between two collision vehicles?

• A. Point of impact
• B. Primary contact
• C. Final position
• D. Secondary contact

Answer: (B)

First contact between two collision vehicles is called the primary contact. This term refers to the moment the two vehicles first touch, starting the crash sequence. It captures the initiation of the collision, not just where the touch occurs. The location of the contact on each vehicle is described as the point of impact, which is about where the force is applied rather than labeling the event itself. The final position describes how the vehicles end up after the crash, not the initial touch. Secondary contact would be any additional contact that happens after the first touch, such as other parts of the vehicles contacting later in the sequence.
