Public scales in St. George / Cedar City (I-15)
Three CAT Scales verified on the operators’ own location pages along I-15 through southwestern Utah, south to north: Pilot #775 Saint George (Exit 4), Love’s #335 Cedar City (Exit 62), and TA Express Parowan #0186 (Exit 78). Useful for U-Haul and PPM moves between Las Vegas and Salt Lake City, RVs and toy haulers headed for Zion, Cedar Breaks or Brian Head, and horse trailers on I-15. Heading southwest toward Las Vegas, the next verified CAT cluster is on Las Vegas / I-15 (Flying J Mesquite #1171 still omits CAT on its own amenities list, so it is not listed here).

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 between Mesquite and Parowan
Utah and Nevada do not publish a CDFA-style public-scale grid we can cite for this corridor, and ScaleRegistry’s public-weighing page lists no walk-up house in Washington or Iron County UT. We are not inventing one from industrial scale vendors, 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.
CAT Scales on I-15 through St. George, Cedar City and Parowan
We list only stops verified on the operator’s own location page. Pilot #775 lists CAT Scale in its own amenities and answers yes to “has a CAT scale”; Love’s #335 lists CAT Scales among amenities; TA Express Parowan #0186 lists CAT Scale on TA Petro’s own page. 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. Utah weighmaster rules differ from California — confirm ticket needs with your TO or DMV equivalent. Use CAT’s locator for other stops.
Pilot Flying J’s own Pilot #775 page says Open 24 Hours and lists 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.
Pilot’s own Saint George page (I-15 Exit 4) lists CAT Scale among amenities and answers yes to “Does this location have a CAT scale?”. Washington County UT; south end of the St. George / Cedar City I-15 corridor, about 40 miles northeast of Mesquite NV. Useful for Zion / St. George U-Haul and RV weigh-ins. CAT 2,000 lb floor; no corner weights. Utah 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.
Love’s own #335 page lists the store and Truck Care 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 Cedar City page (I-15 Exit 62) lists CAT Scales among amenities. Iron County UT; about 50 miles northeast of St. George on I-15. Handy for Cedar Breaks / Brian Head and the mid-corridor weigh between St. George and Parowan. CAT 2,000 lb floor; no corner weights. Utah 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.
TA Petro’s own TA Express Parowan #0186 page says Shell gas or diesel 24/7 and lists CAT Scale among amenities. That is not the same as a published CAT-staffing schedule. Confirm the scale is working before a middle-of-the-night trip.
TA’s own Parowan location page (I-15 Exit 78) lists CAT Scale among amenities (and RV Dump). Iron County UT; about 20 miles northeast of Cedar City — northern end of this corridor page before Beaver. CAT 2,000 lb floor; no corner weights. Utah 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.
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 St. George, Cedar City or Washington/Iron County with an operator page that sells walk-up weighmaster certificates. Flying J Dealer #1171 Mesquite (I-15 Exit 118) and Flying J Dealer #509 Beaver (I-15 Exit 112) still omit CAT Scale from their visible amenities lists — held back (same FAQ-yes / amenities-omit pattern as Wells/Wendover). No Love’s own-page CAT confirmed at Littlefield / Beaver Dam AZ or Hurricane UT. Livestock policy everywhere. Store-listed 24h vs published CAT staffing.
