The tri-shield insignia with distinctive, diagonally arranged red, white and blue shields, was widely introduced in 1960 and was featured front-and-center in the grilles of the LeSabre, Electra and Invicta models. The three-model lineup inspired the three shields in the new design. Each carried over the stag head and gold cross cues from the previous single-shield design. As with the original shield design, the tri-shield design evolved. By the early 1970s, a ring motif surrounded the shields and the white color of one of the shields changed to silver. By the late 1970s, the tri-shield was used primarily on hood ornaments on some models, while the symbol of a hawk on the Buick name was used as the official logo, particularly in print and television advertising.
Concrete Safety Shapes. When most people think of concrete barriers, they think of the New Jersey Concrete Safety Shape Barrier (NJ-shape or Jersey barriers). For the more common shallow-angle hits, the NJ-shape is intended to minimize sheet metal damage by allowing the vehicle tires to ride up on the lower sloped face.(See figure 1.).ach of these concrete barrier types fills a niche and helps meet the needs of highway agencies that select, design, and locate traffic barriers. In terms of safety performance, the 1070-mm (42-in) F-shape is currently our best technology.
