Overtaking Vehicle on right shoulder
Hey all. I have a legal question about a traffic law within the state of Pennsylvania, in regard to overtaking a left-turning vehicle at a stoplight intersection, using a paved shoulder wide enough to safely execute the pass. This is assuming it is a two-lane road. Here is the legalese:
Title 75, Section 3304 indicates that a driver "may overtake and pass upon the right of another vehicle only under one of the following conditions: (1) When the vehicle overtaken is making or about to make a left turn, except that such movement shall not be made by driving off the berm or shoulder of the highway."
My interpretation of this is that you CAN use the shoulder, but if you were to drive OFF the shoulder (say, into grass or dirt, or anything unpaved) it would be an illegal maneuver. If you weren't allowed to use the shoulder at all for such maneuvering, why wouldn't the verbiage be changed from "off" to "on"? If it was changed to "on," that would immediately rule out using the shoulder at all. But then, if the word was "on," there would be no point in this law, as the would always be an illegal maneuver.
Ultimately, if this was an illegal maneuver, can someone provide an example of a legal execution of this situation? Otherwise, what is the point of this particular law in the first place? I am finding the verbiage to be ambiguous, and poorly worded.
Thanks for any insight! And for some background, I was not pulled over for this. Just curious, as I do this on frequent occasion at some traffic lights where I live due to two-lane roads with no protected left turn.
