In the Fall of 2020, NHTSA announced its plan to publish an Interim Final Rule (IFR) to set a new regulation allowing entities to request exemptions to operate nonconforming vehicles, on public roads for purposes of research, investigations, demonstrations, training, competitive racing events, show, or display, but not sale or lease. The IFR also would have pursued new submission and reporting requirements for vehicles to be exempted under the new regulation, mirroring those applicable to exempted imported vehicles. NHTSA is now developing a NPRM.
