Well having looked at the Wyoming code, nothing says in black and white to not use highway pegs.
Quote:

31-5-115. Operation of motorcycles and pedestrian vehicles.

(a) A person operating a motorcycle shall ride only upon the permanent and regular seat attached thereto and shall not carry any other person nor shall any other person ride on a motorcycle unless the motorcycle is designed to carry more than one (1) person, in which event a passenger may ride upon the permanent and regular seat if designed for two (2) persons, or upon another seat firmly attached to the motorcycle at the rear or side of the operator.

(b) A person shall ride upon a motorcycle only while sitting astride the seat, facing forward, with one (1) leg on each side of the motorcycle.
NOTE: One leg on each side of the motorsickle...

(c) No person shall operate a motorcycle while carrying any package, bundle or other article which prevents him from keeping both hands on the handlebars, or obstructs his vision, or interferes with the operation of the motorcycle.

(d) No operator shall carry any person, nor shall any person ride in a position that will interfere with the operation or control of the motorcycle or the view of the operator.
NOTE: This is where an officer may hassle you...

(e) All motorcycles are entitled to full use of a lane and no motor vehicle shall be driven in such a manner as to deprive any motorcycle of the full use of a lane. Two (2) motorcycles may be driven abreast in the same lane by consent of both motorcycle drivers.

(f) The operator of a motorcycle shall not overtake and pass any vehicle in the same lane occupied by the vehicle being overtaken, except another motorcycle. The operator of a motorcycle overtaking another motorcycle in the same lane shall first match the speed of the motorcycle being overtaken.

(g) No person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles.

(h) Subsections (f) and (g) of this section do not apply to police officers in the performance of their official duties.

(j) Motorcycles shall not be operated three (3) or more abreast in a single lane.

(k) No person riding upon a motorcycle shall attach himself or the motorcycle to any other moving vehicle on a roadway. This does not prohibit attaching a motorcycle trailer or motorcycle semitrailer to a motorcycle if the trailer or semitrailer was designed for the attachment.

(m) Any motorcycle carrying a passenger, other than in a sidecar or enclosed cab, shall be equipped with footrests for the passenger.

(n) No person shall operate any motorcycle with handlebars so positioned that the hands of the operator, when upon the grips, are above shoulder height when the operator is sitting astride the vehicle seat with the vehicle in an upright position.

(o) No minor shall operate or ride nor shall the operator permit a minor to ride upon a motorcycle unless he is wearing protective headgear securely fastened on his head, and of a type which complies with standards established by the superintendent. This subsection does not apply to persons riding within an enclosed cab nor to persons operating or riding a moped. This subsection only applies to motorcycles used on public highways, streets and thoroughfares.

(p) Any person operating a motorcycle or pedestrian vehicle shall have the headlamps of the motorcycle or pedestrian vehicle activated at all times, including daylight hours.

(q) Operators of motorcycles operating in an officially authorized parade are exempt from subsections (e) through (o) of this section.

The standard for protective headgear shall meet or exceed the Z90.1-1971 standard of the American National Standards Institute. However, all existing equipment meeting the Z90.1-1966 standard of the American National Standards Institute shall be accepted.

(s) This section applies to motor-driven cycles unless otherwise provided.




The Wyoming Motorcycle Operating Manual does make mention of
Quote:

• Feet — Keep your feet firmly on the footpegs to maintain balance. Don’t drag your feet. If your foot catches on something, you can be injured and it could affect your control of the motorcycle. Keep your feet near the controls(Aha! but this is the handbook NOT the code) so you can get to them fast, if needed. Also, don’t let your toes point downward — they may get caught between the road and the footpegs.



I do read some sections where an officer that is having a bad day may interpret the code in a way to say no highway pegs, but I would argue that point before a judge. Remember cops have arrest power. It is the Judge who will decide things...You'll only pi$$ off the cop if ya argue!
