Roadside delineator device

A breakaway roadside delineator device comprising:

• an upper body fixedly attached to an upper post;
• a lower body fixedly attached to a lower post, wherein the lower post is sunk into ground to hold the delineator device in place;
• a pair of shear pins, wherein the shear pins include a plurality of V-shaped grooves that act as shear points when the upper post is struck by a vehicle;
• the lower body further comprising four buttress-like longitudinal corners, each corner comprising a longitudinal aperture, the apertures being longitudinally aligned, wherein the four buttress-like corners form a longitudinal U-shaped channel and a crosswise U-shaped channel;
• the upper body further comprising a hollow longitudinal body attached to the upper post, the upper hollow body shaped to fit into the lower body longitudinal U-shaped channel, the upper body further comprising side portions shaped to fit into the lower body crosswise U-shaped channel, the side portions further comprising longitudinal apertures aligned with the lower body longitudinal apertures;
• the upper body removably attached to the lower body by the pair of shear pins inserted and spanning the longitudinally aligned lower and upper body apertures;
• and
• whereby when a vehicle hits the upper post, the pair of shear pins breaks causing the upper body and the upper post to separate from the lower body and lower post.
