To park legally, how close must a vehicle be to the curb?

In Washington State, the law stipulates that a vehicle must be parked no more than 12 inches away from the curb. This regulation is designed to ensure that vehicles are parked close enough to the curb to avoid obstructing the roadway and to allow for adequate space for other vehicles and pedestrians. Parking too far from the curb can create safety hazards, as it may force other vehicles to maneuver around the parked car, increasing the risk of collisions. Additionally, adhering to this regulation helps maintain the flow of traffic and facilitates easier movement for others using the road, including cyclists and pedestrians.
