The bill amends several sections of the General Laws in Chapter 31-25, which pertains to size, weight, and load limits for vehicles. Key changes include the introduction of exemptions for road machinery when actively participating in work in an active work zone or crossing a highway within a work zone, as well as specific provisions for farm vehicles and public transit authority vehicles. The maximum length for articulated buses has been increased from forty feet to forty-five feet. New definitions and regulations regarding axle load limits have been established, specifying that single axle weight limits shall not exceed twenty-two thousand four hundred pounds (22,400 lbs.) or the gross axle weight rating as set by the manufacturer.

Additionally, the bill introduces a requirement that vehicles equipped with lift axles must have them down whenever carrying a load, with penalties for violations set at one hundred dollars ($100). It outlines the process for obtaining special permits for vehicles exceeding standard size or weight limits, including an annual blanket permit for non-divisible construction equipment. The blanket construction equipment permit shall supersede the requirements of the divisible load permit and may not exceed one year.

Travel restrictions for oversized vehicles during peak hours and on certain holidays, including Juneteenth, are also specified, along with penalties for operating without the required permits or exceeding permit limits. Overall, the act aims to modernize and clarify the regulations governing vehicle size, weight, and load limits in the state.
