Sound off: Are stop signs in grocery store parking lots legally enforceable?
Officer Jim Welsh of the Lawrence Police Department’s Traffic Safety Unit provided this information:
The stop signs that are often in front of the buildings directly are not enforceable because they are on private property. Examples would be the stop signs in front of Hy-Vee or in front of Michaels/World Market.
The stop signs posted at the edges of the parking lot are technically enforceable, although we would not write it as a stop sign violation. The violation would be failure to yield the right of way when entering a roadway. This violation is enforceable if a stop sign is posted or not. In other words: You have to stop when leaving private property, whether it is posted or not.
