Where can I easily find info regarding which state's laws say (outside from the law section on carseats) that a child still needs to be boostered until am adult belt fits properly...so that it's really not out of a booster at age 7, 8 or 9, but really toll the 5 point test is passed. I know a tech pointed me to PA'S section, but how do I find others for when we travel and take around others kids? Need specifically CA, CT, NJ, MA.
