SB 1182 Missouri Senate · 2026 Regular Session

Authorizes the Missouri Department of Transportation to provide vehicle weight exemptions for certain vehicles

This bill allows Missouri counties to grant temporary weight exemptions for specific trucks transporting solid waste between cities and approved disposal facilities, or hauling construction materials to active economic sites. It permits vehicles to exceed standard axle weight limits (22,400 lbs per axle, 44,800 lbs for tandem axles) within county jurisdictions, while maintaining federal interstate weight limits and standard vehicle size restrictions. The exemptions directly affect waste haulers, construction companies, and counties managing local road infrastructure. The policy change simplifies logistics for these operations without altering federal weight regulations.

MODERATE

The bill was reclassified from an introduced version to a Senate Committee Substitute, indicating it has undergone review and revision. The primary substantive change is the expansion of weight limit exemptions: the original text only allowed exemptions for trucks transporting solid waste, while the new version adds a second provision allowing similar weight exemptions for trucks transporting materials or equipment to construction sites. Additionally, the new version includes specific distance limits (16 miles one-way) and requires trips to be multimodal within a single county.

Scope change

The bill's scope was expanded from exclusively covering solid waste transport to also include construction material transport, though both categories remain subject to stricter distance and routing requirements than the original text implied.

SCOPE

Added a new provision allowing weight limit exemptions for trucks transporting materials or equipment to construction sites, in addition to the existing exemption for solid waste transport.

REQUIREMENT

Introduced new distance restrictions limiting one-way trips to 16 miles and round trips to 32 miles for vehicles seeking these exemptions.

Added a requirement that exempted trips must be multimodal and occur within a single county.

ENFORCEMENT

Clarified that exemptions are granted by the Missouri Department of Transportation if the vehicle qualifies, regardless of whether the load weight can be reduced.
