Information
The dataset contains DMV-registered medium- and heavy-duty vehicles licensed for operation on California roads. However, it does not necessarily include vehicles that operate off of California roads. For example, some medium- and heavy-duty ZEVs may operate only within a port facility and not be registered, while other vehicles of the same make and model may be licensed with the DMV for operation on roads because they occasionally do so. In addition, the data does not include direct electric trolleybuses, which draw power directly from overhead wires. This dashboard is a continually evolving effort solely using DMV registration data, so there may also be some data gaps with actual ZEVs operating in the state (e.g., pilot projects, extremely low-volume conversions, off-road operations, etc.).
