An improved automatic underride protection actuator for a trailer, the trailer being translatable over a ground surface, includes a rotatable ramp that is shiftable between a ground engaging load/unload disposition when the tiltable bed is in the load/unload disposition and an underride protection disposition when the tiltable bed is in the transport disposition. The ramp underride protection disposition is a disposition in which the ramp depends from a tiltable trailer bed the ramp and is rotatably displaceable from the ramp underride protection disposition by impact oft the ramp with the ground surface, such displacement substantially preventing damage.
