DOTTED LINES
A DOTTED LINE is a special marking used to extend other lines. [MUTCD Section 3B.08] It may be an extension of a lane line or centerline through an intersection, or it may be a curved DOTTED line through an intersection to help guide turning vehicles as they move through their turn. A DOTTED line may extend an edgeline, especially where the road widens out for an added lane for deceleration or turning.

A DOTTED line also indicates that a lane will become an "EXIT ONLY" lane and will not continue past the next exit ramp. [MUTCD Section 3B.05]
