Using a kei vehicle in California
While Californiadoesn't allow kei vehicles on public roads, you can still use one:
- Off-road on private property — farms, ranches, estates, and large properties
- Gated communities and private roads— where public road laws don't apply
- Commercial/industrial sites — warehouses, campgrounds, resorts
Some California owners register their kei vehicle in another state. Research the legal implications carefully — this is a gray area that some states are beginning to crack down on.
