A crash attenuation system having an improved, controlled axle release mechanism for a truck trailer mounted attenuator. The axle release mechanism has an axle release insert disposed within an outer bursting tube which is urged downstream by a mandrel resulting in controlled shearing of the fasteners passing through different size elongated slots in the insert and retaining the insert within the bursting tube. Differential shear forces cause the fasteners to shear at different times as the insert is urged downstream resulting in a controlled release of the breakaway axle assembly.
