RCW 46.61.400

Basic rule and maximum limits.

(1) No person shall drive a vehicle on a highway at a speed greater than is reasonable and prudent under the conditions and having regard to the actual and potential hazards then existing. In every event speed shall be so controlled as may be necessary to avoid colliding with any person, vehicle or other conveyance on or entering the highway in compliance with legal requirements and the duty of all persons to use due care.

(2) Except when a special hazard exists that requires lower speed for compliance with subsection (1) of this section, the limits specified in this section or established as hereinafter authorized shall be maximum lawful speeds, and no person shall drive a vehicle on a highway at a speed in excess of such maximum limits.

(a) Twenty-five miles per hour on city and town streets;

(b) Fifty miles per hour on county roads;

The maximum speed limits set forth in this section may be altered as authorized in RCW 46.61.405, 46.61.410, and 46.61.415.

(3) The driver of every vehicle shall, consistent with the requirements of subsection (1) of this section, drive at an appropriate reduced speed when approaching and crossing an intersection or railway grade crossing, when approaching and going around a curve, when approaching a hill crest, when traveling upon any narrow or winding roadway, and when special hazard exists with respect to pedestrians or other traffic or by reason of weather or highway conditions.

Speed traps defined, certain types permitted — Measured courses, speed measuring devices, timing from aircraft.

(1) No evidence as to the speed of any vehicle operated upon a public highway by any person arrested for violation of any of the laws of this state regarding speed or of any orders, rules, or regulations of any city or town or other political subdivision relating thereto shall be admitted in evidence in any court at a subsequent trial of such person in case such evidence relates to or is based upon the maintenance or use of a speed trap except as provided in subsection (2) of this section. A “speed trap,” within the meaning of this section, is a particular section of or distance on any public highway, the length of which has been or is measured off or otherwise designated or determined, and the limits of which are within the vision of any officer or officers who calculate the speed of a vehicle passing through such speed trap by using the lapsed time during which such vehicle travels between the entrance and exit of such speed trap.

(2) Evidence shall be admissible against any person arrested or issued a notice of a traffic infraction for violation of any of the laws of this state or of any orders, rules, or regulations of any city or town or other political subdivision regarding speed if the same is determined by a particular section of or distance on a public highway, the length of which has been accurately measured off or otherwise designated or determined and either: (a) The limits of which are controlled by a mechanical, electrical, or other device capable of measuring or recording the speed of a vehicle passing within such limits; or (b) a timing device is operated from an aircraft, which timing device when used to measure the elapsed time of a vehicle passing over such a particular section of or distance upon a public highway indicates the speed of a vehicle.

(3) The exceptions of subsection (2) of this section are limited to devices or observations with a maximum error of not to exceed five percent using the lapsed time during which such vehicle travels between such limits, and such limits shall not be closer than one-fourth mile.

RCW 46.61.525

Negligent driving — Second degree.

(1)(a) A person is guilty of negligent driving in the second degree if, under circumstances not constituting negligent driving in the first degree, he or she operates a motor vehicle in a manner that is both negligent and endangers or is likely to endanger any person or property.

(b) It is an affirmative defense to negligent driving in the second degree that must be proved by the defendant by a preponderance of the evidence, that the driver was operating the motor vehicle on private property with the consent of the owner in a manner consistent with the owner’s consent.

(c) Negligent driving in the second degree is a traffic infraction and is subject to a penalty of two hundred fifty dollars.

(2) For the purposes of this section, “negligent” means the failure to exercise ordinary care, and is the doing of some act that a reasonably careful person would not do under the same or similar circumstances or the failure to do something that a reasonably careful person would do under the same or similar circumstances.

(3) Any act prohibited by this section that also constitutes a crime under any other law of this state may be the basis of prosecution under such other law notwithstanding that it may also be the basis for prosecution under this section.

Minimum speed regulation — Passing slow moving vehicle.

(1) No person shall drive a motor vehicle at such a slow speed as to impede the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or in compliance with law: PROVIDED, That a person following a vehicle driving at less than the legal maximum speed and desiring to pass such vehicle may exceed the speed limit, subject to the provisions of RCW 46.61.120 on highways having only one lane of traffic in each direction, at only such a speed and for only such a distance as is necessary to complete the pass with a reasonable margin of safety.

(2) Whenever the secretary of transportation or local authorities within their respective jurisdictions determine on the basis of an engineering and traffic investigation that slow speeds on any part of a highway unreasonably impede the normal movement of traffic, the secretary or such local authority may determine and declare a minimum speed limit thereat which shall be effective when appropriate signs giving notice thereof are erected. No person shall drive a vehicle slower than such minimum speed limit except when necessary for safe operation or in compliance with law.

RCW 46.61.180

(2) Upon a roadway which is divided into three lanes and provides for two-way movement of traffic, a vehicle shall not be driven in the center lane except when overtaking and passing another vehicle traveling in the same direction when such center lane is clear of traffic within a safe distance, or in preparation for making a left turn or where such center lane is at the time allocated exclusively to traffic moving in the same direction that the vehicle is proceeding and such allocation is designated by official traffic-control devices.

(3) Official traffic-control devices may be erected directing slow moving or other specified traffic to use a designated lane or designating those lanes to be used by traffic moving in a particular direction regardless of the center of the roadway and drivers of vehicles shall obey the directions of every such device.

(4) Official traffic-control devices may be installed prohibiting the changing of lanes on sections of roadway and drivers of vehicles shall obey the directions of every such device.
