This bill establishes an immediate exemption for stinger-steered combinations that are transporting assembled highway vehicles from a federal requirement to include warning flags on projecting loads. Specifically, it states that section 393.87 of title 49, Code of Federal Regulations, which mandates such flags, will no longer apply to these specialized automobile transporters. Furthermore, the legislation directs the Secretary of Transportation to revise this regulation to formally incorporate the exemption. This revision is mandated to be carried out as soon as practicable and notably, without engaging in the standard notice and comment or any other formal rulemaking process, thereby expediting its implementation.
