It takes a lot of vehicles to move 154 billion pieces of mail each year. And a lot of fuel to power those vehicles.
While the Postal Service’s Postal Vehicle Services (PVS) fleet is a small part of the entire fleet — about 4,300 vehicles made up of cargo vans, tractors, and smaller tractor-trailers known as spotter vehicles — it is a crucial part. PVS vehicles move mail between processing facilities, inner-city delivery offices, and local businesses and mailers. Their usual travel distance is about a 50-mile radius.
