In the context of crash investigations, what constitutes a 'multi-vehicle crash'?

A 'multi-vehicle crash' is defined as a crash involving more than one vehicle. This typically means that two or more vehicles are directly involved in the incident, which can include a range of scenarios such as collisions between cars, trucks, and motorcycles. Understanding this definition is crucial for traffic crash investigations, as it helps to categorize the complexity of the incident, determine fault, assess the extent of damages and injuries, and identify the contributing factors, which may vary significantly from a single-vehicle crash.

The other options provided do not align with the definition of a multi-vehicle crash. For instance, a single vehicle losing control pertains to a situation where only one vehicle is involved, which would not meet the criteria for classification as a multi-vehicle crash. Similarly, the option referring to only crashes involving trucks specifies a type of vehicle rather than the number of vehicles involved, while accidents occurring at intersections can involve multiple types of collisions, but this context alone does not specifically define a multi-vehicle crash. Thus, the correct understanding of a multi-vehicle crash encompasses any situation where multiple vehicles are involved in the same incident.
