What is meant by the term "underride" in vehicle collisions?

The term "underride" in vehicle collisions specifically refers to one vehicle colliding with another and sliding underneath it. This situation often occurs in incidents involving larger vehicles, such as trucks, where passenger cars may become lodged under the trailer or body of the truck during the collision.

Understanding this term is crucial for rescue technicians, as it impacts both the dynamics of the crash and the methods used during extrication. In underride incidents, victims might be trapped in their vehicles, requiring specialized techniques to safely remove them without causing further injury.

The other definitions do not align with the specific scenario described by "underride." While one vehicle resting on top of another would describe a scenario known as "overriding," a vehicle rolling over in a collision refers to a different type of crash altogether, and skidding off the road does not involve one vehicle colliding under another. Each of these other scenarios represents distinct collision dynamics that would involve different rescue strategies.
