Yes, Californians are allowed to use snow socks as a traction device in California. Although you cannot compare the quality of snow socks to that of chains, Californians have permission to use snow socks. However, this permission is limited because they can only use it if snow chains are unavailable. The reason is that snow socks are fabrics that can tear easily. Unlike snow socks, chains have heavy steel that makes them durable. So in California, you cannot use snow socks if chains are available.
