The utility model discloses a speed reduction and antiskid marking suitable for road sections of a tunnel entrance and a tunnel exit, which comprises a section of continuous longitudinal antiskid marking respectively arranged at the tunnel entrance and the tunnel exit along the traffic direction, a plurality of speed reduction markings transversely distributed at interval on the road section outside the tunnel entrance along the traffic direction, and a plurality of speed reduction markings transversely distributed at interval on the road section inside the tunnel exit along the traffic direction. The antiskid marking extends from the outside of the tunnel to the inside of the tunnel and comprises a resin-based adhesive bottom layer, an antiskid aggregate wear-resisting layer and a color surface layer, wherein a resin-based adhesive of the bottom layer is directly painted on the pavement; antiskid aggregates of the wear-resisting layer are uniformly spread on the resin-based adhesive bottom layer; and the color surface layer is painted on the antiskid aggregate wear-resisting layer. The speed reduction markings are the convex structural speed reduction markings. The utility model has reasonable design, convenient construction and good using effect, has good safety warning and antiskid functions, and can effectively solve the problem of traffic safety on the road sections of the tunnel entrance and the tunnel exit.
