§47-11-301.


    (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;
    4.  Upon a roadway restricted to one-way traffic; or
    5.  Upon a roadway having four or more lanes for moving traffic
and providing for two-way movement of 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 when
available for traffic, or as close as practicable to the right-hand
curb or edge of the roadway and may be temporarily driven upon the
right-hand shoulder for the purpose of permitting other vehicles to
pass.  This subsection shall not apply 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 paragraph 2 of subsection (a) 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
alley, private road or driveway.
