Right turn on red question

[LittleRedToyota]

hey yinz...

i've got a question about PA's right turn on red law...specifically, my question is "what defines a right turn?"

(here is the statute if anyone is interested: http://members.aol.com/StatutesP1/75PA3112.html but it does not seem to define "right turn".)

there are two intersections near my house...one of which i go through everyday on my way home from work...where i'm not really quite sure if i am making what would legally qualify as a "right turn" (and, so, am not sure if i can legally "turn right" on red at the intersection).

here is the situation with one of the intersections...

there is one road, center avenue, that is the "main road". it curves. there is another road (with a different name, but i don't remember it offhand, let's just call it "other road") that is, geometrically speaking, a "straight" tangent off of the curve of center avenue.

(note that other road begins/ends at center avenue, so this is a three-way intersection, not a typical 4-way intersection. this is somewhat akin to a Y intersection except the left side of the Y goes straight, but is a different road. so the base and right uppper half of the Y is center avenue. the left upperhalf of the Y is other road, but it is in a straight line with the lower part of the Y rather than bending off to the left. there is a stoplight at the intersection.)

so, as you are heading down center avenue, you more or less "turn" right to stay on center avenue. if you go geometrically "straight", you end up on other road (after crossing oncoming center avenue traffic). so, for all intents and purposes, going onto other road is a left turn...even though you don't actually turn your steering wheel at all to go that way--as it is geometrically a straight line.

going in that direction, if the light is red on center avenue, can you continue on center avenue after stopping at the red light? on one hand, you are physically turning right, but, on the other hand, you are conceptually "staying straight" on center avenue. you do *not* cross any lanes of traffic though. (really, this should just be an always-on green arrow since you are not allowed to turn left onto center avenue from other road anyway, but for some stupid reason it is not.)

my real question, though (as i do this every day), is about coming from other street onto center avenue. if you are on other street approaching center avenue and stop at the red light...

you are technically turning right from other street onto center avenue, but you don't actually physically turn...rather you go straight. so, my question is, can i "turn right" (physically go straight) on red from other street onto center avenue? note that you do not cross any lanes of traffic in doing so...it really is just like a normal right turn except that you don't actually turn right from a geometric standpoint.

hope that explanation wasn't too confusing...these types of intersections exist all over, so i'm sure you have gone through them.
