Can you change lanes over a single white line?

[MacClayton]

Single white lines do not permit lane changes. As long as it's a solid line, lane changes are prohibited. The purpose of white solid lines is to separate lanes traveling in the same direction, and they are typically painted before traffic lights at intersections. Below is more information about various road markings: Yellow lines: Yellow lines are used to divide opposing lanes of traffic. A solid yellow line prohibits crossing the line; a dashed yellow line allows for turns or U-turns when there is no oncoming traffic. White lines: White solid lines indicate lanes moving in the same direction and prohibit crossing into another lane traveling the same direction; white dashed lines indicate lanes moving in the same direction and permit crossing into another lane traveling the same direction.
