Public scales in McCammon / Idaho Falls (I-15)
Two CAT Scales verified on Flying J’s own location pages along I-15 in eastern Idaho: Flying J #641 McCammon (I-15 Exit 47, at US-30 south of Pocatello) and Flying J #1043 Idaho Falls (I-15 Exit 113). Useful for U-Haul and PPM moves into Pocatello or Idaho Falls, RVs headed to Yellowstone or Island Park, and horse trailers on the Snake River Plain. Heading south into Utah, the previous verified cluster is on Brigham / Ogden / I-15 (Brigham City Exit 363). TA Express Dubois #0940 (I-15 Exit 137) does not list a CAT Scale on its own page — not included.
This page lists 2 places to weigh near McCammon & Idaho Falls, ID: 2 CAT or truck-stop scales. They are in McCammon and Idaho Falls. 2 are listed as likely to print a certified weight ticket, the kind PPM movers and RV owners checking weight ratings usually need. CAT platforms have a 2,000 lb minimum and do not give corner weights.
Filters hide cards, not industrial rows. CAT will not weigh under 2,000 lb — use a dedicated house for cars and empty utility trailers.
No verified dedicated public scale house on eastern Idaho I-15 tonight
Idaho does not publish a CDFA-style public-scale grid we can cite for this corridor, and ScaleRegistry’s public-weighing page lists no walk-up house in Bannock or Bonneville County ID. We are not inventing one from industrial scale vendors, grain elevators, recyclers, landfill gate scales, or third-party trucker directories. Every stop below is a CAT Scale at a truck stop, verified on the operator’s own page.

We list only stops verified on the operator’s own location page. Both Flying J pages list CAT Scale in amenities and answer yes to “has a CAT scale.” 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. Idaho weighmaster rules differ from California — confirm ticket needs with your TO or DMV equivalent. Use CAT’s locator for other stops.
Flying J’s own #641 page lists the store as Open 24 Hours and CAT Scale 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.
Flying J’s own McCammon page (I-15 Exit 47, at US-30) lists CAT Scale among amenities and answers yes to “has a CAT scale.” Bannock County ID, south of Pocatello where US-30 splits off toward Lava Hot Springs and Soda Springs. Useful for PPM / U-Haul and RV weigh-ins coming up from Utah on I-15. CAT 2,000 lb floor; no corner weights. Idaho weighmaster rules differ from California — confirm ticket needs with your TO or DMV equivalent. Do not unload horses in the lot. Confirm on CAT’s locator. Not a DOT station.

Flying J’s own Idaho Falls page (I-15 Exit 113) lists CAT Scale among amenities and answers yes to “has a CAT scale.” Bonneville County ID; north end of this corridor toward Rexburg, Yellowstone and the Montana line. Useful for PPM / U-Haul moves into Idaho Falls and RVs heading to Yellowstone or Island Park. CAT 2,000 lb floor; no corner weights.

Idaho port-of-entry and highway weigh / commercial-enforcement sites on I-15 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 Pocatello, Blackfoot, Idaho Falls or Bannock/Bingham/Bonneville County with an operator page that sells walk-up weighmaster certificates. A Pocatello-proper or Blackfoot CAT stop on an operator’s own page (none found tonight). Love’s Idaho own-page locations could not be loaded tonight. Livestock policy everywhere. Store-listed 24h vs published CAT staffing.
