Hwy 46 between Paso Robles and the east Hwy 46-41 split. This is a double fine zone and you must drive with your headlights on. The 35 mile long area is very busy with patrol cars. I was driving 55 (the posted limit) and was passed by 6 cars. All 6 were tagged within 10 miles of passing me. They hide everywhere. Bad place is east bound, about 1.5 from the Paso Robles Dump. You are comming down a grade to a bridge. From the 46-41 split to I-5 on both highways is also has a high amount of patrols, however not a double fine zone.
