A retractable speed barrier system includes a winged speed barrier assembly, a lateral pivoting assembly that includes a plurality of trapezoidal hinges, a hollow frame assembly, and an electrically activated linear actuator. The winged speed barrier assembly is attached to the hollow frame assembly by the lateral pivoting assembly. The linear actuator causes the winged speed barrier assembly to laterally pivot on the trapezoidal hinges in a direction perpendicular to the flow of traffic between a retracted position and a deployed position.
