Solid white lines are used to mark an intersection that a driver must stop at before entering whilst obeying all right-of-way laws. Dashed white lines are used to mark an intersection at which a driver must give way. Dashed white lines are also commonly used to indicate turns in intersections and to indicate intersections where a diamond turn is possible (intersections in which two cars traveling in opposite directions turn to the same direction-of-travel as each other without coming into contact).
