This standard covers the safety requirements for all tricycles intended for use by children 8 years and under. While the addition of a push handle does not by itself change the classification of a product from a tricycle to a stroller (or other juvenile product), there exist in the marketplace some hybrid products (i.e., tricycle/stroller combinations that have canopies, reclining seats, and/or restraint systems, etc.) that are intended and marketed to fulfill both functions.
