If it is legal to turn right on a red light after first stopping then please do so. Sitting there waiting until all the traffic has gone is a irritating to all the traffic waiting behind you. And if you have a merge lane then you really don't have an excuse to sit there holding up traffic.
Another tip is for drivers coming off a clover leaf in an attempt to merge with vehicles moving at speeds much greater than yours. Be mindful that you will have at least a half a kilometre to get up to speed and make your merge. You are wrong to cut in front of faster moving traffic until you get up to their speed. The last time I saw this driving error almost killed the stupid driver who cut in front of a semi tractor trailer when they had a whole half a kilometre to get up to speed before merging. Take my advice on these driving tips before you kill yourself or someone else.
