How often courts cite this section
Court decisions citing this, by year.Markers show enactment, consequential amendments, and circuit splits over this section — watch for a citation surge after a change or a disagreement. The dip in the last several years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the most recent years, so recent citations are undercounted.

The words “as required under this chapter and regulations prescribed by the Secretary of Transportation under this chapter” are substituted for “in accordance with the provisions of sections 22 to 29 and 31 to 34 of this title” for clarity and consistency. In clause (3), the words “prescribed by the Secretary under this chapter” are substituted for “prescribed in the rules and regulations hereinafter provided for” for clarity and because of the restatement.
