If i have to make a left with right of way and thrre’s a car on the side street also turning left and there is no other traffic, why not let him go?
Either i slow down, wave him out, he pulls out in front of me, then i can make a leisurely left onto the side street.
Or, i have to more cautiously turn and avoid his vehicle, then he can pull out after me. It makes less sense that way, especially if road conditions are less than ideal, or lanes are narrow and visibility for him is poor. Which it usually is in sw pa.
Stop except if turning left. Stop except if turning right. Stop when going straight, etc., etc., etc. Sometimes they appear totally random and make no sense at all.
My neighborhood is full of stop signs on straight streets to let in side traffic from seldom used streets. We like it that way because it is residential and we don't appreciate people speeding through where there are kids, old people walking dogs and the like. So it makes sense.
But you get out in the country here where houses are a half mile apart or more, and they are still doing this kind of stuff. I swear it is nothing more that a way to raise revenue on people unfamiliar with the idiosyncrasies of local road design.
