I don't even think this ticket involves points....
§ 3111. Obedience to traffic-control devices.
(a) General rule.--Unless otherwise directed by a uniformed
police officer or any appropriately attired person authorized to
direct, control or regulate traffic, the driver of any vehicle
shall obey the instructions of any applicable official traffic-
control device placed or held in accordance with the provisions
of this title, subject to the privileges granted the driver of
an emergency vehicle in this title.
(b) Proper position and legibility of device.--No provision
of this title for which official traffic-control devices are
required shall be enforced against an alleged violator if at the
time and place of the alleged violation an official device is
not in proper position and sufficiently legible to be seen by an
ordinarily observant person. Whenever a particular section does
not state that official traffic-control devices are required,
the section shall be effective even though no devices are
erected or in place.
(c) Presumption of authorized placement.--Whenever official
traffic-control devices are placed or held in position
approximately conforming to the requirements of this title, the
devices shall be presumed to have been so placed by the official
act or direction of lawful authority, unless the contrary shall
be established by competent evidence.
(d) Presumption of proper devices.--Any official traffic-
control device placed or held pursuant to the provisions of this
title and purporting to conform to the lawful requirements
pertaining to such devices shall be presumed to comply with the
requirements of this title, unless the contrary shall be
established by competent evidence.

The officer cut him a big break, I think. This ticket doesn't carry any points as far as I can tell. It's lower than a speeding ticket.
