Section 32-5A-80

Driving on right side of roadway; exceptions.

THIS SECTION WAS AMENDED BY ACT 2021-520 IN THE 2021 REGULAR SESSION, EFFECTIVE AUGUST 1, 2021. THIS IS NOT IN THE CURRENT CODE SUPPLEMENT.

(a) Upon all roadways of sufficient width, a vehicle shall be driven upon the right half of the roadway, except under any of the following conditions:

(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 doing so 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.

(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). 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.

(d)(1) Upon any interstate highway, except as provided in subdivision (2), a vehicle may not remain in the leftmost lane for more than 1.5 miles without completely passing another vehicle.

(2) A vehicle may travel in the leftmost lane under any of the following conditions:

a. When traffic conditions or congestion make it necessary to operate a vehicle in the leftmost lane.

b. When inclement weather, obstructions, or hazards make it necessary to operate a vehicle in the leftmost lane.

c. When compliance with a law, rule, ordinance, or traffic control device makes it necessary to operate a vehicle in the leftmost lane.

d. When exiting a roadway to the left.

e. When paying a toll or user fee at a toll collection facility.

f. If the vehicle is an authorized emergency vehicle operated in the course of duty.

g. If the vehicle is operated or used in the course of highway maintenance or construction or is traveling through a construction zone.

(3) The Department of Transportation shall cause to be installed appropriate signs giving notice of this subsection. The department shall place the signs within the first two miles of the beginning of any interstate highway in the state and, where practical, every 50 miles thereafter, and at any intersection of interstate highways. At its discretion, the department may adjust placement of a sign to a location beyond an on-ramp if it falls within close proximity to a specified 50-mile increment and may adjust placement to avoid conflicts with existing signage already in place along the interstate corridor.
