The Postal Service is in the process of acquiring new delivery vehicles, including electric vehicles, to replace its aging delivery fleet. While some will be commercial, off-the-shelf vehicles, most will be Next Generation Delivery Vehicles (NGDVs), which are purpose built to the Postal Service’s specifications. The OIG has published several reports about the Postal Service’s purchase process and preparations. In 2014, we found the Postal Service had not fully implemented its strategy for replacing delivery vehicles because of funding constraints. We recommended USPS continue to pursue its short-term plan of buying some new vehicles each year, while it worked to finalize its long-term plan.
