Driving CDL in California
California is one of the toughest states to drive CDL in the country, and one of the most lucrative for the right setup. CARB clean-truck enforcement is the most aggressive in the US, so newer equipment is effectively required for fleet work — if you're owner-op, plan the truck purchase around it. Drayage out of LA / Long Beach and warehouse-rotation work in the Inland Empire pay near the top of the national scale, but cost of living is brutal. The mountain passes (Cajon, Grapevine, Donner) add real winter complexity that most other Southwest lanes don't. Drivers with serious mountain experience earn it back.
