Fire Apparatus Operations and Hydraulics Practice Test

Pump and roll lets you discharge water while the apparatus is moving, so water can be applied as you advance toward the fire. This is made possible by powering the pump from the vehicle’s engine—often through a PTO or a dedicated pump engine—so the pump keeps delivering water even as the truck is in motion. This capability helps you reach the fire faster and maintain forward progress without constant stops to set up, reposition, or restart.

This isn’t about pumping at lower pressure only when stationary, nor is it about automatically elevating a ladder or automatically mixing foam at the discharge. Those functions are separate systems or features and do not define the pump-and-roll capability.
