One Response to Wisconsin

  • I am trying to clear up some confusion on the booster seat requirements… My son is 9-years old and is UNDER 4’9″. Does he need to be in a booster seat? We live in Wisconsin, but will be traveling in Washington, Oregon and California next month. I am having trouble clarifying if he needs a booster seat because he is over 8-years old, but under the 4’9″. I am not sure if the requirement is an ‘either-or’ requirement or an ‘and’ requirement. Thank you for your help!! Sueann Baerwald
