What does a white line on the right side of the road indicate?

A white line on the right side of the road typically indicates the boundary of the travel lane. This serves to delineate the edge of the roadway and shows where the vehicle should ideally be positioned while driving. It helps drivers understand their location relative to the road and encourages safe driving practices by discouraging vehicles from veering off the road surface.

While emergency parking areas, the end of a travel lane, and recommended speed limits are critical traffic elements, they are represented by different markings or signs. A solid white line, for instance, is utilized to indicate that crossing into another lane is discouraged, further emphasizing safe traffic flow rather than being associated with emergency or speed signage.
