Step-by-step explanation:
If an adjuster needs to find clarification about what actually constitutes a collision, the information would typically be found in the Definitions section of an insurance policy. This section is designed to clearly explain the terms and concepts used throughout the policy, ensuring that both the insurer and the insured have a mutual understanding of the coverage. For example, a definition of 'collision' would detail the specific scenarios that the insurance company recognizes as a collision incident.
