In subsection (a), the words "may prescribe or enforce . . . only if the standard is identical" are substituted for "no . . . shall have any authority to establish or enforce with respect to . . . which is not identical" to eliminate unnecessary words. The words "a standard prescribed under section 32502 of this title" are substituted for "Federal bumper standard" for clarity.

The words "a bumper standard about an aspect of performance . . . not covered by a standard prescribed under section 32502 of this title" are substituted for "Until a Federal bumper standard takes effect with respect to an aspect of performance" and "any bumper standard which is applicable to the same aspect of performance of such vehicle or item of equipment" to eliminate unnecessary words. The words "if the State bumper standard" are added for clarity.

In subsection (c), the words "that imposes additional or higher standards of performance than" are substituted for "which is not identical to . . . if such requirement imposes an additional or higher standard of performance" for clarity and to eliminate unnecessary words.
