> If we are going to be pedantic about this, and you pretty much have to be given the topic, a parking violation is not considered a traffic violation. Obviously a private parking lot isn't some completely lawless place, but many (most?) traffic laws don't apply there.
So you can drive like 50 mph or do donuts, violate crosswalks with pedestrians in them, etc? Does your jurisdiction have no laws on reckless driving, exhibition of motor, etc?
Sure the stop sign might not be the legal height required by your roadway authority but see if that stops a cop from citing you if you blow through it without observing traffic (aka drive recklessly).
Hell, I know people who have received seat belt tickets while operating a motor vehicle in a parking lot.
