Public scales on Hwy 99 / Stockton approaches

Four CAT Scales verified on Pilot Flying J and Love’s own location pages for the CA-99 / Stockton approaches: Flying J #618 and Love’s #223 at Ripon (CA-99 Exit 237 / 237B), plus ONE9 #1361 and Love’s #538 at Lodi (I-5 Exit 485 — the north-of-Stockton interchange that feeds Hwy 99 traffic). No ScaleRegistry dedicated walk-up house in Stockton / Manteca / Ripon. CDFA San Joaquin / Stanislaus grids did not load on this compile (WAF blocked). Modesto Truck Plaza / Vanco Stockton appear on third-party CAT directories only — omitted until an operator page confirms CAT for this directory.

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 this corridor

ScaleRegistry’s California public-weighing list still points to Selma and Merced for the broader Central Valley — no Stockton / Manteca / Ripon / Modesto dedicated house. Use the Central Valley page for Selma and Merced. We are not inventing a civilian ticket shop from third-party trucker directories.

Do not go here for a ticket

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.

What we still need to verify

Full CDFA San Joaquin and Stanislaus public-scale grids (blocked on this compile). Any dedicated walk-up weighmaster house in Stockton / Manteca / Modesto with an operator page. Modesto Truck Plaza (Hwy 99 Exit 223) and Vanco Truck & Auto Plaza (Stockton / I-5 Exit 471) appear on third-party CAT directories — omitted until an operator page or CAT’s own locator confirmation is used as our primary source for this directory. Love’s #736 Madera and Pilot #365 Madera now ship on the Madera / Hwy 99 page. ONE9 #1424 Westley has no CAT amenity on Pilot’s page. Lat/lng for Love’s Ripon and Love’s Lodi. Livestock policy everywhere.
