stroyed during transportation, the car-
rier shall replace all the missing or
damaged identification numbers as
soon as practicable. However, in such a
case, the numbers may be entered by
hand on the appropriate placard, or-
ange panel or white square-on-point
display configuration providing the
correct identification numbers are en-
tered legibly using an indelible mark-
ing material. When entered by hand,
the identification numbers must be lo-
cated in the white display area speci-
fied in § 172.332. This section does not
preclude required compliance with the
placarding requirements of subpart F
