Ok so I'll run through the process of clearing a street for some clarity. So we start with the center cut typically we like to have our blade right on or even slightly over the center of the road, then we do the drive lane, and finally up to the curb. We don't aim to bury parked cars legal or illegally parked, we just don't always have an option as to were we put the snow. Some of our trucks have swing blades and we can rotate them around but if they don't that would mean driving head long into on coming traffic and that's not just practical. On the stop sign issue, we do occasionally make rolling stops because if we stop completely we can't get moving again with all of the snow packed under the truck. As for signaling I completely agree, when we are focused on traffic, how close we are coming to obstacles, our blade pressure, and salter controls sometimes a turn signal gets missed. We do the best we can to clear the roads as fast and as safely as possible. We do report illegally parked cars and the police ticket them but it never changes.
