So I just had an argument with my girlfriend and rather than continuing it, decided to simply ask you professionals. So here's the question: when you're in a left turn only lane and the light is green (but no arrow), are you allowed to enter the intersection and wait for traffic to clear before you make your turn? I'm curious specifically about Indiana state laws, but other state laws would be interesting to hear also. I've included the relevant (at least from what I can tell) section of the Indiana Code, but couldn't figure out the answer for myself from it.
Signals exhibiting colored lights; requirements; explanation of colors
Sec. 7. (a) Whenever traffic is controlled by traffic control signals exhibiting different colored lights or colored lighted arrows successively, one (1) at a time or in combination, only the colors green, red, or yellow may be used, except for special pedestrian signals under IC 9-21-18.
(b) The lights indicate and apply to drivers of vehicles and pedestrians as follows:
(1) Green indication means the following:
(A) Vehicular traffic facing a circular green signal may proceed straight through or turn right or left, unless a sign at the place prohibits either turn.
(B) Vehicular traffic, including vehicles turning right or left, shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection or an adjacent sidewalk at the time the signal is exhibited.
(C) Vehicular traffic facing a green arrow signal, shown alone or in combination with another indication, may cautiously enter the intersection only to make the movement indicated by the green arrow or other movement permitted by other indications shown at the same time.
(D) Vehicular traffic shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to other traffic lawfully using the intersection.
(E) Unless otherwise directed by a pedestrian control signal, pedestrians facing a green signal, except when the sole green signal is a turn arrow, may proceed across the roadway within a marked or unmarked crosswalk.
