In the presented situation, can you stop the vehicle on the shoulder before the sign?

Why?

The B-36 no stopping sign has a T-25c plate with a downward arrow, marking the end of the restriction. Before this sign, the restriction still applies, including on the right-hand shoulder. You therefore cannot stop there voluntarily.
