On November 1, 2000, Congress passed the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act, Public Law 106-414 (114 Stat. 1800). Under that Act, the Secretary of Transportation was required to develop a child restraint safety rating that was practicable and understandable (Section 14 g) in order to help consumers make an informed decision in the purchase of a child restraint. In addition, Section 14(b)(9) of the TREAD Act required consideration for placing child restraint systems (CRS) in the rear seats of vehicles being crash tested under the New Car Assessment Program (NCAP).
