N.M. Stat. § 66-7-315
No-passing zones.
A. The state transportation commission and local authorities may determine those
portions of any highway under their respective jurisdictions where overtaking and
passing or driving on the left of the roadway would be especially hazardous and may, by
appropriate signs or markings on the roadway, indicate the beginning and end of such
zones. When the signs or markings are in place and clearly visible to an ordinarily
observant person, every driver of a vehicle shall obey the directions of the signs or
markings.
B. Where signs or markings are in place to define a no-passing zone as set forth in
Subsection A of this section, no driver shall at any time drive on the left side of the
roadway within the no-passing zone or on the left side of any pavement striping
designed to mark the no-passing zone throughout its length.
C. This section does not apply under the conditions described in Paragraph (2) of
Subsection A of Section 66-7-308 NMSA 1978 or to the driver of a vehicle turning left
into or from an alley, private road or driveway.
