Delivering more than 40% of the world's mail and reaching every business and residential address in America six days a week requires the dependable, ubiquitous vehicle fleet of the U.S. Postal Service. The world's largest civilian fleet delivers more than 167 billion pieces of mail to more than 150 million addresses, along 230,000 routes, logging 4 million miles a day, with 215,000 postal vehicles, of which more than 44,000 are alternative fuel-capable.
