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 stretch

ScaleRegistry’s California public-weighing list still points to Selma and Merced for the broader Central Valley — not a Grapevine or Patterson walk-up house. Use the Central Valley page for those dedicated houses. 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) — including Grapevine-area enforcement sites — 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 Kern, Merced, and Stanislaus public-scale grids (blocked on this compile). Lat/lng for Love’s Santa Nella and Love’s Patterson. Other I-5 CAT stops whose own pages list CAT (Madera, Firebaugh-area, etc.). Hwy 99 Ripon / ONE9 Lodi / Love’s Lodi are on Hwy 99 / Stockton. West Sacramento CAT #3390 still third-party only. Livestock policy everywhere.
