Washington State Car Seat Laws

  • Children up to their 8th birthday, unless they are 4'9" tall (which ever comes first), must ride in a child restraint. (For example a child car seat, booster seat, vest, or other restraint that is federally approved for use in the car.)
  • The restraint system must be used correctly according to the car seat AND vehicle manufacturer's instructions.

Best Practices For Car Seats
  • have a child ride rear facing until the maximum allowed in your convertible car seat. The new recommondation by the American Academy of Pediatrics is 2 years of age. (read more here https://aapnews.aappublications.org/cgi/content/citation/30/4/12)
  • have a child ride in a harness as long as possible. Many car seats have harnesses that go to 65 lbs now. Including all the convertible car seats that Crbaby Comforts rents for this reason.
  • have a child ride in a booster until the 4'9" magic number no matter what the age of the child is.
  • Children under 13 years old be transported in the back seat where it is practical to do so.
  • Children 8-years of age or at least 4'9" who wear a seat belt MUST use it correctly (never under the arm or behind the back) or continue to use a booster.
  • Vehicles equipped with lap-only seat belts are exempt from the requirement to use a booster seat
