This is incorrect. Red light means stop, for right turning vehicles.
You probably konfius it with "no green arrow also can turn".

For right turn, red means cannot turn at all lah. Refer to the link you gave. I reproduce for your convenience. Sendiri post link, sendiri tak baca

No wonder Malaysian drivers find it dangerous. Red pun can turn right? Since when?

Red light means cannot turn right. Don't listen to those ignorant people here who create own rules.
Discretionary right turn means the round green light is on (traffic going straight can move) but green right arrow is not on yet. If no oncoming car or adjacent got no pedestrians, you can turn right.

The advantage of this system is it allows traffic from both directions to move, only those turning right must practise discretionary turn or wait for green arrow.

When green arrow is not on and the round red light is on, both traffic going straight and turning right must stop.
In example below, you can only turn right when green arrow is on, because the round red is on. When the green arrow is off (no red arrow here) and red light is on, you must not turn.

Just added two years ago? Wrong again. Again, red means stop. Your own link already proved you wrong.

You grew up in Sin and yet you don't know the traffic rules? Not surprising if you don't have a licence or you don't drive.

If you have other proof of "red can turn right", or the so-called change 2 years ago, please share. Else, we'll just stop here.

Exactly.

No worries, glad we sorted this out.

Descretionary left turns are not that many in Singapore. There is always a clear sign that says "turn left on red" or something like that. Meaning you cannot suka suka do descretionary left turn if there is no sign that says so, therefore it's less confusing. Macam U turn - one can only do U turn when you see the U turn sign.
