An occurrence in cities that get snow where roads that may have once been nicely divided into 3 lanes turn into two very distinct lanes due to the tracks which are repeatedly driven in. Such snowlanes adhere to no actual laws, rhyme or reason but merely the easiest and most common paths to drive. At any given time you may find that the snowlane you are driving in appears to be directly in the middle of two lanes and the dividing line is right in the middle of your lane. This is acceptable and there's really nothing you can do until the snow plows clear it, or if its forged in ice, the spring comes.
"What the fuck, the white line is right in the middle of this snowlane"
"Ya in the spring there's actually three lanes on this road but I guess it got turned into two snowlanes"
