emphasis mine.

B. Any motor vehicle in use on a highway shall be equipped with, and required signal shall be given by, a signal lamp or lamps or mechanical signal device when the distance from the center of the top of the steering post to the left outside limit of the body, cab or load of such motor vehicle exceeds twenty-four inches, or when the distance from the center of the top of the steering post to the rear limit of the body or load thereof exceeds fourteen feet. The latter measurement shall apply to any single vehicle, also to any combination of vehicles.

Looks like TX is the same..

Is it an infraction to use a hand signal in NM?
If not, why the stop?

Just wondering.
