The purpose of this legislation is to exempt a specific type of vehicle, known as stinger-steered combinations, from a federal requirement that mandates the use of warning flags on loads that extend beyond the vehicle's normal dimensions. This exemption applies when these vehicles are transporting assembled highway vehicles, such as cars or trucks. The key provision of the law states that starting from the date it is enacted, stinger-steered combinations will no longer be required to display warning flags on their loads.
