PHP код:

if(!IsPlayerConnected(playerid)) return 0; 


This can be deleted as you need to be connected to execute a command anyway.

PHP код:

if(PlayerInfo[playerid][pRank] < 3) 


Shouldn't this be

PHP код:

if(PlayerInfo[playerid][pRank] >= 3) 


This would mean your rank needs to be at 3 or higher to execute this command.

PHP код:

SendClientMessage(playerid, COLOR_GREY, "Your rank is too low to set a Road Block!"); 


The command is used to destroy roadblocks, but your message indicates that you would create a roadblock, it's confusing.

And it could be written like this:

PHP код:

if(strcmp(cmd, "/rrb", true) == 0)
{
    if(PlayerInfo[playerid][pRank] < 3) return SendClientMessage(playerid, COLOR_GREY, "Your rank is too low to set a Road Block!");
    if(PlayerInfo[playerid][pFaction] != 255 && FactionInfo[PlayerInfo[playerid][pFaction]][fType] == 1)
    {
        for(new o = 0; o < MAX_OBJECTS; o++)
        {
            DestroyObject(RoadBlockObject[o]);
            RoadBlocks = 0;
        }
        SendClientMessage(playerid, COLOR_WHITE, "All Road Blocks destroyed..");
    }
        
    return 1;
}
