No verified dedicated public scale house in the Tri-Cities tonight
We have not found a walk-up public scale house in Franklin or Benton County with an operator page we can cite, and ScaleRegistry’s public-weighing page lists none here. We are not inventing one from industrial scale vendors, grain elevators, recyclers, landfill or transfer-station gate scales, or third-party trucker directories. Both stops below are CAT Scales at Love’s Travel Stops, verified on Love’s own location pages.
CAT Scales in Pasco and Prosser
We list only stops verified on the operator’s own location page. Both Love’s #811 and Love’s #681 list CAT Scales in their amenities and list the store as open 24 hours — that is store hours, not a published CAT-staffing schedule. 2,000 lb floor. No corner weights. Weigh the whole rig, then drop the trailer and weigh the tow vehicle for the trailer number. Do not unload horses at a truck stop. Washington weighmaster rules differ from California — confirm ticket needs with your TO or licensing office. Use CAT’s locator for other stops.
Love’s own #811 page lists the store as Open 24-Hours and CAT Scales among amenities. That is the store’s hours, not a published CAT-staffing schedule. Confirm the scale is working before a middle-of-the-night trip.
Love’s own Pasco page lists CAT Scales among amenities; exit is Kartchner St on US-395 (Love’s publishes a street exit, not a mile number). Franklin County WA; Tri-Cities (Pasco, Kennewick, Richland). CAT 2,000 lb floor; no corner weights. Washington weighmaster rules differ from California — confirm ticket needs with your TO or licensing office. Do not unload horses in the lot. Confirm on CAT’s locator. Not a DOT station.
Love’s own #681 page lists the store as Open 24-hours (Truck Care 6 a.m. – 11 p.m.) and CAT Scales among amenities. Store hours are not a published CAT-staffing schedule. Confirm the scale is working before a middle-of-the-night trip.
Love’s own Prosser page (I-82 Exit 80 at Gap Rd) lists CAT Scales among amenities. Benton County WA; Yakima Valley, about 34 miles straight-line west of the Pasco stop. CAT 2,000 lb floor; no corner weights. Washington weighmaster rules differ from California — confirm ticket needs with your TO or licensing office. Do not unload horses in the lot. Confirm on CAT’s locator. Not a DOT station.
Washington State Patrol weigh stations on I-82 and US-395 are for commercial vehicles — not a place to buy a civilian weighmaster ticket for a U-Haul, RV, boat, horse trailer, or PPM load. Follow posted signs; do not treat this directory as a bypass guide.
What we still need to verify
Any dedicated public scale house in Pasco, Kennewick, Richland, Benton City or Prosser with an operator page that sells walk-up weighmaster certificates. CAT-scale staffing hours at both Love’s stops (only store hours are published). TA Grandview (I-82 Exit 73) does not list a CAT Scale on TA’s own page, so it is not listed. Livestock policy everywhere.
