Massachusetts vs New York

Massachusetts has a reputation as a strict state, but on car seats New York is the more protective of the two. The reason is rear-facing. New York requires a child under 2 to ride rear-facing. Massachusetts sets no rear-facing age at all: its law requires a child under 8 to be in a child restraint unless they are taller than 57 inches, but it never names a rear-facing requirement. So a parent who turns a 14-month-old forward is breaking the law in New York but not in Massachusetts. On the booster rule the two states match, which is why rear-facing is the deciding factor.

Both states require a child to stay in a car seat or booster until age 8 or 4 feet 9 inches (about 57 inches), and both release a child to a seat belt at that point. So for the booster question, Massachusetts and New York give the same answer. Pediatricians recommend keeping a child in a booster until the seat belt fits properly, usually around 4 feet 9 inches, in both states.

The two real differences both favor New York. First, New York requires rear-facing under 2 and Massachusetts does not set a rear-facing age. Second, Massachusetts exempts vehicles for hire such as taxis from its child restraint requirement, while New York's rule applies more broadly with no general taxi exemption. So in New York a child generally needs the correct restraint even in a taxi, while Massachusetts carves that out. Neither state requires children to ride in the back seat, though both recommend it for children under 13.

The fines are close: New York's civil fine is $25 to $100 for a violation involving a child under 8, and Massachusetts sets a $25 fine. New York can waive a first offense if you buy an appropriate restraint. The booster rule and the fine are effectively a wash, so the comparison comes down to rear-facing and the taxi exemption, both of which make New York stricter. If your child is under 2, meeting New York's rear-facing rule will satisfy Massachusetts too.
