UPDATE: New law will require temporary license plates in California starting in 2019.
When you buy a brand new car, a used car, or re-register your old car in Arizona, you can go online and print a 30-day temporary tag while your official license plate is being made. On a recent visit to California, I noticed a lot of brand-new vehicles driving around without license plates. These cars had a plastic plate and frame with the name of the dealership, but nothing else.
This got me wondering: does California not require temporary tags on motor vehicles?
