right lane must turn right means when you're in the right lane you're supposed to turn right and not go straight. if it's a red light you can turn right with caution unless there is a sign that you're not allowed to turn right when the light is red, pag may red arrow light or sign na you're not supposed to turn on red light then you can only turn right when the traffic light becomes green. again if you're on the right lane and there is a sign that says right lane must turn right you're supposed to turn right when the light becomes green and not go straight. pero dito sa atin all traffic signs are just a suggestion.
dami ko nakikita na nasa right lane na may sign "right lane must turn right" tapos di naman pala kakanan. pag binusinahan mo sila pa galit. eh di nila alam dapat pag nan don ka kumanan ka. kaya nag tataka ako kung bakit kelangan pa ng drivers license sa atin eh kung sino sino lang naman nakaka kuha, basic traffic rules and traffic signs di alam.
