41-6a-701. Duty to operate vehicle on right side of roadway -- Exceptions.
(1) On all roadways of sufficient width, a person operating a vehicle shall operate the vehicle on the right half of the roadway, except:
(a) when overtaking and passing another vehicle proceeding in the same direction under the rules governing that movement;
(b) when an obstruction requires operating the vehicle to the left of the center of the roadway subject to the provisions of Subsection (2);
(c) on a roadway divided into three marked lanes for traffic under the applicable rules; or
(d) on a roadway designed and signposted for one-way traffic.
(2) A person operating a vehicle shall yield the right-of-way to a vehicle:
(a) traveling in the proper direction on a roadway; and
(b) that is within a distance constituting an immediate hazard.

i am thinking that the vehicle i passed was an obstruction, pursuant to 1b, due to the fact that they were on their cell phone and driving erratically. the man on his cell phone was not constituting an immediate hazard (except to me, and breaking the law) and they were an obstruction, IMO.
