Atkinson is an English-language surname. The name is derived from a patronymic form of the Middle English Atkin.
These are much more conservative than state laws, in general (for instance, everyone should be in a booster seat from about age 4 to at least age 8) but remain less conservative than some of the european standards (for instance, the European Child Safety Alliance recommends that children remain in rear-facing carseats until 3 years of age).
The current version of the law requires that all children under 4 years of age are restrained in an approved child passenger restraint system, and children between 4 and 8 years of age are restrained in a booster seat. Beginning in August, the new law expands this by specifically requiring children under age 2 to ride rear-facing. There two types of car seats that can be used rear-facing: convertible car seats and infant-only car seats.
