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.
Except as provided in sections 202(a)(5), 203(a)(3), and 205(a) of this title, the Secretary is authorized to prescribe and promulgate all needful rules and regulations for the carrying out of the provisions of this title. The Secretary may make such recommendations to the Congress and State transportation departments as he deems necessary for preserving and protecting the highways and insuring the safety of traffic thereon.
