Lincoln, NE – Attorney General Hilgers filed an antitrust lawsuit against some of the nation’s largest heavy-duty truck manufacturers for an alleged plot to stifle the availability of internal-combustion semi-trucks in favor of electric ones. Rather than push back or simply compete in the marketplace, heavy-duty truck manufacturers colluded to sign an agreement called the “Clean Truck Partnership.” The agreement commits the signatory manufacturers not to oppose additional state-level electric-truck mandates and to restrict output of diesel-powered semi-trucks in lockstep, even if a court rules that the regulations are unlawful. The antitrust lawsuit alleges that truck manufacturers have illegally conspired to anticompetitively reduce the output of internal-combustion trucks to protect their own economic interests.
