{
if(newstate == PLAYER_STATE_DRIVER)
        {
           if(pData[playerid][pMission] == MISSION_TYPE_TRUCK_2)
           {
               new vehicleid;
               vehicleid = GetPlayerVehicleID(playerid);
               if(!IsTrailerAttachedToVehicle(vehicleid))
               {
                 return SendClientMessage(playerid, RED, "ATTACT TRAILR");
               }
           }
        }
