made several mistakes
1. changed lane uncessarily before left turn
2. forgot changing to the most right lane after left turn
3. officer said I didn't do shoulder check for several lane change. I answered him I did.
1. I told the officer I hate parrelell parking. He only asked me to pull over to the road side do an 'emergency pull over' . No three point turn, no parrelell.
2. traffic on the high way was heavy. I didn;t need to worry about speed limit. I drove at 50 KM/Hr
