Final answer:
The law in Washington state requires vehicles to be within 6 inches of the curb when parallel parking.
Step-by-step explanation:
The correct answer is A) Within 6 inches.
In Washington state, the law stipulates that when parallel parking, vehicles must be within 6 inches of the curb. This distance ensures that there is enough space for other vehicles to pass safely, reduces the risk of damage to the parked car, and facilitates efficient traffic flow.
By parking within 6 inches of the curb, drivers can also avoid obstructing pedestrians on the sidewalk and maintain visibility for approaching vehicles. It's crucial to follow parking regulations to ensure the safety and convenience of all road users.
