Try this..

pawn Код:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate == PLAYER_STATE_DRIVER)
    {
        new vid = GetPlayerVehicleID(playerid);
        if(vid == 597 || vid == 599 && gTeam[playerid] == CIVILIAN)
        {
            RemovePlayerFromVehicle(playerid);
            SendClientMessage(playerid, COLOR_YELLOW, "You can NOT Enter a Police Vehicle");
        }
    }
    return 1;
}

But, what's the problem?
