Well the CHP still has fixed wings registered to them. Ex N137HP https://registry.faa.gov/AircraftInquiry/Search/NNumberResult?nNumberTxt=137HP https://registry.faa.gov/AircraftInquiry/Search/NNumberResul... You can track them on ADSBExchange: https://globe.adsbexchange.com/?icao=a095ef https://globe.adsbexchange.com/?icao=a095ef And they were in the air yesterday with flight paths along major freeways in the SF Bay Area: https://imgur.com/a/u5hbfAK https://imgur.com/a/u5hbfAK Does that mean conclusively they are doing speed checks? No, but they have the capability. Does the CHP have a lot of these planes? Not that I can find records of, probably few and far between for a state as populous as California... but the treat is real.
