California learners navigate Silicon Valley express lanes, LA HOV corridors, and Tahoe snow in one state. The DMV’s 2025 manual refresh highlights clean-air rules, Vision Zero enforcement, and online testing logistics. Structure study sessions across three tracks: urban commuting (metered ramps, bus rapid transit lanes, protected intersections), coastal/freeway travel (carpool sticker rules, toll express lanes, fog on Highway 1), and mountains/deserts (chain controls on I-80, heat-related breakdowns in the desert, wildfire evacuation). App explanations cite California Vehicle Code so you see the legal foundation behind each answer. Finish sessions by comparing teen curfews with handheld device penalties—hybrid questions like these are common on the 46/36-question exam.
