Can you change lanes on a single white line?

[Jean]

You cannot change lanes on a single white line. As long as it is a solid line, lane changing is not allowed. The purpose of the white solid line is to separate lanes in the same direction, usually marked in front of traffic lights at intersections. Here is more information about various road markings: 1. Yellow lines: Yellow lines are used to divide opposing lanes. Among them, a solid yellow line prohibits crossing the line; a dashed yellow line allows turning or making a U-turn when there are no oncoming vehicles. 2. White lines: A solid white line indicates lanes moving in the same direction, and you cannot cross into another lane moving in the same direction; a dashed white line indicates lanes moving in the same direction, allowing you to cross into another lane moving in the same direction.
