====Solid White Lines====
It is not illegal to cross a solid white line in the state of Wisconsin, unless posted [https://docs.legis.wisconsin.gov/statutes/statutes/346/II/13/3 Wisconsin Statute 346.13(3)]. Solid white lines such as road edge lines, lane divider lines, or on/off ramp lane lines. Even though it is not illegal, it is good safe driving practice to not cross these lines. When mapping on/off ramps, ensure that the junction is placed before the the solid white line begins, or after it ends.
