well make the taxi cars into like new taxi1,taxi2; so under your gamemode it should bel ike this

pawn Код:

taxi1 = CreateVehicle...
taxi2 = CreateVehicle...

Under onplayerstatechange do this

pawn Код:

if(GetPlayerVehicleID(playerid) == taxi1)
    {
        if(PlayerData[playerid][TaxiDriver] == 0)
        {
            SendClientMessage(playerid,0xFF0000FF,"ERROR: You are not a taxi driver");
            RemovePlayerFromVehicle(playerid); 
            }
    }
    if(GetPlayerVehicleID(playerid) == taxi2)
    {
        if(PlayerData[playerid][TaxiDriver] == 0)
        {
            SendClientMessage(playerid,0xFF0000FF,"ERROR: You are not a taxi driver");
            RemovePlayerFromVehicle(playerid); 
            }
    }
