The present invention relates to the technical field of traffic safety accessory devices, in particular to an emergency avoidance protection device for highways, which can improve the deceleration ability of automobiles, can effectively decelerate automobiles with large kinetic energy until they stop, and improve safety; and can Effectively prevent the car from stopping and the cargo rushing out due to inertia, avoiding losses; including sequentially connected driving-in area, first deceleration area, first buffer area, second deceleration area, second buffer area, and third deceleration area and the collision buffer zone, both ends of the first deceleration area are provided with triangular supports, and multiple sets of roller shafts are arranged between the two sets of triangular supports, and the two ends of the multiple sets of roller shafts are rotationally connected with the two sets of triangular supports through ball bearings. The first buffer zone is provided with the first interception net, the second deceleration zone is provided with artificial sand, the second buffer zone is provided with the second interception net, the third deceleration zone is provided with medium sand, and the collision buffer zone is provided with anti-collision barrels and elastic damping plate.
