Federal Motor Vehicle Safety Standards: Occupant Crash Protection

This final rule amends the Federal motor vehicle safety standard (FMVSS) on occupant crash protection to remove the sunset of a requirement that a vehicle's lap belt must be lockable, without the use of special tools, to tightly secure a child restraint system (CRS). We refer to this as the "lockability" requirement. Under the current standard, the lockability requirement ceases to apply to seating positions that are equipped with a child restraint anchorage system (commonly referred to as a "LATCH" system) on vehicles manufactured on or after September 1, 2012. Because data indicate that motorists are still using lockable belts to install CRSs even in seating positions with LATCH, there is a continuing need for the lockability requirement even in seating positions with LATCH. Thus, this final rule ensures that the lockability requirement continues in effect for all seating positions past September 1, 2012.
