CONSTITUTION: A guardrail apparatus comprises multiple posts(10), a guardrail plate(30), multiple block-outs(20), a post stiffener(50), and a guardrail beam(40). One end of the multiple posts is inserted into the ground(5) and the other end thereof is projected from the ground to support the guardrail plate and the block-outs. A vehicle directly crashes to the guardrail plate which is extended along a road and installed in the front of the multiple posts. The block-outs are interposed between the guardrail plate and the posts to prevent direct crash between the vehicle and the posts. The post stiffener is installed inside the post to support the post on the ground. The guardrail beam is arranged in the rear side of the multiple posts to connect the posts.
