To amend title 23, United States Code, to establish an axle weight tolerance for certain commercial motor vehicles transporting dry bulk goods, and for other purposes.

HR 3318 would allow commercial trucks transporting specific dry bulk goods (like grain or cement in purpose-built trailers) to exceed standard axle weight limits by up to 10%, while still adhering to the overall vehicle weight cap. This change directly affects trucking companies and shippers moving homogeneous nonliquid cargo in specialized trailers. The key provision amends federal law to establish this 110% axle weight tolerance for dry bulk transport, overriding previous axle-specific weight rules except for the maximum gross vehicle weight. It does not alter overall weight restrictions or apply to other types of cargo.
