A shield for a compartment opening of a refuse truck body, comprising an upper segment hinged to the truck body and a lower segment hinged to the upper segment. A source of power selectively pivots the lower segment relative to the upper segment. This enables a first angle of articulation whereby the upper segment covers an upper region of the compartment opening and the lower segment covers a lower region of the compartment opening whereby the shield covers the entire opening of the compartment; a second angle whereby the upper segment covers the upper region of the opening and the lower segment is positioned such that refuse can be swept beneath the lower segment into the lower region of the opening; and a third angle whereby the upper and lower segments fully uncover the compartment opening, whereby refuse can be freely dumped out of the compartment.
