Side topic, and most don't, at least according to the manual you're supposed to read prior to taking your driving test. Hardly anyone comes to a complete stop with the nose of the vehicle behind the line, or behind the stop sign. Most drivers pull up alongside the stop sign, which technically would be running it. Many more don't come to a complete stop after technically running the stop sign, pulling a 'California stop, or a rolling-stop, where the vehicle slows, but is still in motion prior to and through the stop sign. Most people do not read signs, LR, from stop signs, yield signs, Workers Present signs, or even speed limit signs. I understand why they have to be there, for legal reasons, but most people ignore them. Same would go for any pharmecutical sign which was not an advert for a sale of a particular brand of medication. Adverts are methodically examined, warning/disclaimer signs are methodically ignored.
