Pennsylvania lawmakers passed SB481, which raises weight limits for trucks hauling bulk liquid milk to or from dairy farms and milk plants. The bill has cleared the Legislature and is headed to the governor.
Why it matters
Pennsylvania dairy haulers have been at a disadvantage because neighboring Ohio and New York allow heavier milk loads, according to Rep. Ed Neilson. The change is intended to make the state's dairy industry more competitive across the region.
SB481 sets maximum loads of 95,000 pounds for five-axle, 107,000 pounds for six-axle and 117,000 pounds for seven-axle milk trucks, with each non-steering axle limited to 21,000 pounds. Packaged milk does not qualify for the higher limits.
The players
Ed Neilson
Ed Neilson is a Pennsylvania state representative who argued that state dairy haulers are disadvantaged by neighboring states' heavier milk load allowances.
The details
The bill allows the heavier loads for bulk liquid milk traveling to or from dairy farms and milk plants, and they could run seven days a week at any hour unless weather is poor. Separately, House Bill 6428 in Michigan would raise the limit for qualifying farm loads from 80,000 to 90,000 pounds and is under review in the House Transportation Committee.

Roadmap
Pennsylvania's move follows a regional pattern in which neighboring states already permit heavier milk loads, putting the state's dairy haulers at a competitive disadvantage. Michigan's proposed HB6428 reflects a similar push to raise weight limits for farm products across state lines.
Dairy haulers in Pennsylvania could carry substantially more milk per trip if the governor signs SB481, potentially lowering hauling costs for dairy operations. Drivers and carriers would need to observe the new axle-based limits and the restriction that packaged milk does not qualify.
The takeaway
Heavier-load rules for agricultural hauling are spreading across state lines, so dairy producers and carriers should track whether the governor signs SB481 and how axle-based limits are enforced.
