ABSTRACT:
A slotted rail terminal for highway guardrails. The rail of the terminal contains at least one slotted section extending along the rail and having at least one longitudinal slot of a size sufficient to reduce the ability of the rail to resist bending in response to a loading from one end or the side of the rail. A slot guard is provided which is adapted to be attached to the rail on the side facing away from the highway and downstream of each slotted section relative to expected longitudinal loadings on the rail. The slot guard is configured to abut the rail and span its respective slotted section so as to resist enlargement of each slot. The slot guard enables the slotted section to resist and oppose lateral impacting forces such that the slotted section of the guardrail will act to substantially redirect laterally impacting vehicles.
