Do to recent communications with local law enforcement agencies regarding bicycle safety and bicycle traffic laws, I have decided to post some information that I have found.This information was gathered from the Velorution's "The Bike Info Freeware Site". This is here to give you a general decription as to what cyclists need to know about the rules of the road.
"Bicycle" means every device propelled solely by human power upon which a person or persons may ride, having two tandem wheels either of which is sixteen or more inches in diameter, or three wheels, any one of which is more than twenty inches in diameter.
"Hours of darkness" means the hours from one-half hour after sunset to one-half hour before sunrise, and any other time when persons or objects may not be clearly discernible at a distance of five hundred feet.
"Highway" means the entire width between the boundary lines of every way publicly maintained when any part thereof is open to the use of the public for purposes of vehicular travel.
"Roadway" means that portion of a highway improved, designed, or ordinarily used for vehicular travel, exclusive of the sidewalk or shoulder even though such sidewalk or shoulder is used by persons riding bicycles. In the event a highway includes two or more separated roadways, the term "roadway" shall refer to any such roadway separately but shall not refer to all such roadways collectively.
"Vehicle" includes every device capable of being moved upon a public highway and in, upon, or by which any persons or property is or may be transported or drawn upon a public highway, including bicycles. The term does not include devices other than bicycles moved by human or animal power or used exclusively upon stationary rails or tracks. Mopeds shall not be considered vehicles or motor vehicles for the purposes of chapter 46.70 RCW. Bicycles shall not be considered vehicles for the purposes of chapter 46.12, 46.16, or 46.70 RCW.
The Department of Transportation may by order, and local authorities may by ordinance or resolution, with respect to any limited access highway under their respective jurisdictions prohibit the use of any such highway by funeral processions, or by parades, pedestrians, bicycles or other non-motorized traffic, or by any person operating a motor-driven cycle. Bicyclists may use the right shoulder of limited access highways except where prohibited. The Department of Transportation may by order, and local authorities may by ordinance or resolution, with respect to any limited-access highway under their respective jurisdictions prohibit the use of the shoulders of any such highway by bicycles within urban areas or upon other sections of the highway where such use is deemed to be unsafe. The Department of Transportation or the local authority adopting any such prohibitory regulation shall erect and maintain official traffic control devices on the limited access roadway on which such regulations are applicable, and when so erected no person may disobey the restrictions stated on such devices.
The parent of any child and the guardian of any ward shall not authorize or knowingly permit any such child or ward to violate any of the provisions of this chapter.
RCW 46.61.755 Traffic laws apply to persons riding bicycles.
(1) It is a traffic infraction for any person to do any act forbidden or fail to perform any act required in RCW 46.61.750 through 46.61.780.

Every person riding a bicycle upon a roadway shall be granted all of the rights and shall be subject to all of the duties applicable to the driver of a vehicle by this chapter, except as to special regulations in RCW 46.61.750 through 46.61.780 and except as to those provisions of this chapter which by their nature can have no application.
All hand signals required of persons operating bicycles shall be given in the following manner: (1) Left turn. Left hand and arm extended horizontally beyond the side of the bicycle; (2) Right turn. Left hand and arm extended upward beyond the side of the bicycle, or right hand and arm extended horizontally to the right side of the bicycle; (3) Stop or decrease speed.

A person operating a bicycle upon a roadway or highway other than a limited-access highway, which roadway or highway carries traffic in one direction only and has two or more marked traffic lanes, may ride as near to the left side of the left through lane as is safe. A person operating a bicycle upon a roadway may use the shoulder of the roadway or any specially designated bicycle lane if such exists.
