Compared with the prior art, the utility model the advantage lie in: the utility model discloses a highway buffering protector carries out preliminary buffering to the vehicle out of control through setting up the blotter, the blotter drives the buffer beam and slides in the through-hole, can cushion the buffer board at spring one and two restoring forces of spring, because the buffer beam can keep away from one side removal of striking vehicle when the blotter atress, so spring three and spring four can be elongated, the impact force of blotter can be offset to spring three and spring four's elasticity, thereby reach the effect of buffering vehicle once more, this device can absorb the impact force of the vehicle out of control effectively and reduce the damage to the vehicle in the striking process.

As an improvement, the buffer cushion is made of rubber, the rubber has high elasticity of reversible deformation, and the buffer effect is good.

As the improvement, the blotter is equipped with the silica gel sand grip on the arc terminal surface of arc and blotter, is equipped with the frictional force of silica gel sand grip multiplicable blotter and automobile body on the arc terminal surface of blotter to make the vehicle out of control reduce the speed of a motor vehicle, avoid because of the serious traffic accident that the speed of a motor vehicle is too high causes.

As an improvement, the joint of the mounting seat and the upright post is provided with a reinforcing rib, and the reinforcing rib is convenient for reinforcing the upright post, so that the whole device has good stability.

As an improvement, the mounting seat is fastened on the highway pavement through expansion bolts.
