What does the "dash roll" technique achieve in vehicle rescue?

The "dash roll" technique is designed to lower the dashboard away from trapped occupants in a vehicle rescue scenario. This technique is crucial when individuals are pinned underneath the dashboard, often due to a collision where the front end of the vehicle has crumpled. By rolling the dashboard away, rescuers can create more space, making it easier to extricate the occupants without causing further injury.

The use of this technique addresses the immediate need to relieve pressure and access individuals effectively, ultimately improving their chances of a safe removal. In cases where victims are trapped, maintaining a clear pathway for medical interventions is of the essence, and the dash roll technique serves this purpose excellently. The other options do not align with the primary goals of the dash roll method and instead suggest actions that either do not directly assist in freeing trapped individuals or could exacerbate the situation.
