Is parking on a yellow line considered illegal parking?

I was driving along upper Thomson road and when I approached the traffic junction, I stopped at the 2nd lane to the right to turn to SLE (PIE). Upon the the green arrow right turn, I drove my car and suddenly noticed that there are two flash light which made me think that I may had been at the wrong lane and not supposed to turn right. In my more than 10 years of driving in singapore, I was a law abiding drivers who had never broke any traffic rules. I concluded that it may be my wrong judgement that I did not notice the lane marked and had thought that the two right lane are for turning right. There was no vehicle on my side side and either going straight or turning at that time at about 10.30pm. May I know how can I report this matter to the traffic police for my unintentional turn which I thought was allowable until I notice two flash light as there were no vehicles going straight at that time. Thank you very much
