Public scales near Sacramento (I-5 approaches)

Four CAT Scales verified on Pilot Flying J and Love’s own location pages on the I-5 corridor that serves Sacramento: Dunnigan and Williams to the north, Lodi and Lathrop to the south. ScaleRegistry lists no Sacramento dedicated house. CDFA county grids for this corridor did not load (WAF blocked). Pilot Dealer #879 on El Centro Rd in Sacramento lists showers and truck parking but not CAT Scale on Pilot’s amenity list, so it is omitted.

4 verified listings · 1 Yolo · 1 Colusa · 2 San Joaquin · 0 dedicated houses · 4 CAT stops · CDFA grids not loaded

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 in this corridor

ScaleRegistry’s public-weighing page still lists Colton, Lancaster, Merced, and Selma for California — no Sacramento / West Sacramento / Stockton dedicated house. CDFA Sacramento, Yolo, Colusa, and San Joaquin county grids did not load on this compile (WAF blocked). We are not inventing a walk-up house from third-party trucker directories or industrial scale vendors.

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 Sacramento, Yolo, Colusa, and San Joaquin public-scale grids (blocked on this compile). Any dedicated walk-up weighmaster house in metro Sacramento with an operator page. West Sacramento CAT #3390 appears on third-party trucker pages — omitted until CAT’s own locator or a Pilot/Love’s page confirms it for this directory. Other Pilot / Flying J / Love’s / TA CAT stops on I-5 / I-80 whose own pages list CAT. Hwy 99 Ripon / ONE9 Lodi / Love’s Lodi moved to Hwy 99 / Stockton. Livestock policy everywhere. Lat/lng for Love’s Williams.
