Which definition applies to a motor vehicle crash?

The chosen definition accurately describes a motor vehicle crash by specifically encompassing incidents involving motor vehicles while explicitly excluding railways until they are involved in the situation. This distinction is important because it clarifies that the term "motor vehicle crash" is focused on vehicles designed for road use, such as cars and trucks, which aligns with the nature of traffic laws and reporting practices.

This definition is critical for identifying what constitutes a motor vehicle crash as opposed to other types of accidents, such as those involving trains or non-motorized vehicles. By defining it this way, it ensures that data collection and analysis remain relevant to motor vehicle operations, facilitating better safety regulations and enforcement in road traffic scenarios.
