stock IsVehicleEmpty(vehicleid)
{
    new rst = 0;
    for(new i; i < GetMaxPlayers(); i++)
    {
        if(GetPlayerVehicleID(i) == vehicleid) rst = 1;
        if(GetVehicleTrailer(GetPlayerVehicleID(i)) == vehicleid) rst = 1;
    }
    if(rst == 1) return 0;
    return 1;
}

and what's this? "HMOD_CHECK;"

edit: uh wait.. I guess your version would work same good..
however I would add a "IsPlayerConnected" above^^
