Public scales in the Antelope Valley (Palmdale / Lancaster)
Two dedicated / walk-up-style houses already on the Los Angeles County list (ScaleRegistry’s 80′ Lancaster public scales and Sierra Gas & Scale), plus one newly verified CAT Scale on Pilot Flying J’s own Palmdale / Pearblossom Hwy location page: Pilot #1267. Hi-Grade Materials (Lancaster) stays call-first. CDFA Los Angeles (c=19) still loads for the county page; we did not invent hours or fees. I-15 High Desert CAT stops (Hesperia / Barstow) stay on the I-15 / High Desert page.
Filters hide cards, not industrial rows. CAT will not weigh under 2,000 lb — use a dedicated house for cars and empty utility trailers.

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.
