Vermont § 1031 - Driving to right

§ 1031. Driving to right

• (a) Upon all roadways of sufficient width, a vehicle shall be driven upon the right half
  of the roadway, except as follows: (1) when overtaking and passing another vehicle proceeding in the same direction under
  the rules governing such movement; (2) when an obstruction exists making it necessary to drive to the left of the center
  of the highway, provided any person so doing shall yield the right of way to all vehicles
  traveling in the proper direction upon the unobstructed portion of the highway within
  such distance as to constitute an immediate hazard; (3) upon a roadway divided into three marked lanes for traffic under the rules applicable
  thereon; or (4) upon a roadway restricted to one-way traffic. (b) Upon all roadways, any vehicle proceeding at less than the normal speed of traffic
  at the time and place and under the conditions then existing shall be driven in the
  right-hand lane then available for traffic, or as close as practicable to the right-hand
  curb or edge of the roadway, except when overtaking and passing another vehicle proceeding
  in the same direction or when preparing for a left turn at an intersection or into
  a private road or driveway. (c) Upon any roadway having four or more lanes for moving traffic and providing for two-way
  movement of traffic, no vehicle shall be driven to the left of the center line of
  the roadway, except when authorized by official traffic-control devices designating
  certain lanes to the left side of the center of the roadway for use by traffic not
  otherwise permitted to use such lanes, or except as permitted under subdivision (a)(2)
  of this section. However, this subsection shall not be construed as prohibiting the
  crossing of the center line in making a left turn into or from an intersecting highway,
  an alley, private road, or driveway when authorized. (Added 1971, No. 258 (Adj. Sess.), § 3, eff. March 1, 1973.)
