A confused citizen in Jamaica Plain seeks guidance from his municipal elders about that 48-hour period after the end of a snow emergency:
Does a parking spot placeholder negate a No Parking sign?
Chair... awe, this is too easy.
Is the person who marked a spot in a no parking zone killing himself.
The original questioner returns:
The parking spot placeholder in front of a No Parking sign from last night has now been replaced by a vehicle.
"no parking in the middle of the street".
which is where the space saver is.
