Stop for sure means "no forward motion" and I lack the skill some of you have to really do that without putting a foot down. But I can slow to a crawl, ready to stop if needed, then keep moving if there is no traffic. I do it often in my closest town and often at 4-way stops in the next closest town when there is no traffic. Riding/driving in unfamliar towns, I obey the law. I also obey the "stop completely" edict when I enter a highway or street from a mall, rest stop, or whatever. In short, this is a law I only break when I am sure there is no chance of an accident.
About a year ago I violated one of those stop signs in the car. You HAD to roll past the stop sign and line to see if there was a vehicle approaching you under the overpass where I was making a left turn. Legally, I should have made the full stop at the line, then crept forward to see if it was safe to make my turn or I needed to stop again. The hidden cop let me off with a warning, which I found surprising - a mis-placed stop line means numerous violaters and revenue. (Here, I always adhere to the letter of the law, and twice more have found cops in place.)
Very close to my home there is a stop sign which virtually everybody treats as a "yield" sign, and rightly so. Good view up the road for approaching traffic on this T-junction. Only a little farther from my home is a "yield" sign with a very short view of traffic. This is another T-junction. I treat it like a small town stop sign.
Just wondered how you treat stop signs in familiar and unfamiliar territory.
