Public scales on I-5 at Santa Nella
Three CAT Scales verified on TravelCenters of America, Petro, and Love’s own location pages at the Santa Nella I-5 / Hwy 33 cluster: TA #0163 Santa Nella (12310 State Highway 33), Petro #0346 Santa Nella (28991 West Gonzaga), and Love’s #441 Santa Nella (29025 West Plaza Dr / I-5 Exit 407). Love’s #441 also appears on the longer Grapevine / I-5 mid-CA corridor page. No ScaleRegistry dedicated walk-up house at Santa Nella itself (Merced Highway 59 Scales is inland on Central Valley). CDFA Merced grid did not load (WAF blocked). Mid-north Redding / Anderson still only has one own-page CAT (TA Redding #0057) — deferred.
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 at Santa Nella
ScaleRegistry’s California public-weighing list still points to inland Central Valley houses (Selma / Merced / Lancaster) — no Santa Nella dedicated house verified on this compile. Highway 59 Scales in Merced is on the Central Valley page. We are not inventing a civilian ticket shop from third-party trucker directories.

California Commercial Vehicle Enforcement Facilities (CHP weigh stations) are for commercial enforcement — not a place to buy a civilian weighmaster ticket for a U-Haul, RV, horse trailer, or PPM load. See Caltrans’ weigh-station primer and follow posted signs; do not treat this directory as a bypass guide.
