How long are fleets keeping their equipment? This section looks at average fleet size, current age of vehicles, and replacement age of these vehicles. Additionally, it provides a snapshot of total fleet size for all state, county, municipal, and federal fleets, as reported to the federal government.

The most current data available about state and locally-owned fleets from the Federal Highway Administration shows that fleet numbers for these entities stayed relatively stable from the prior year, showing only a 1.4% increase in total motor vehicles.

Statistics about the federal fleet reveal that for the first time in five years, the federal government in 2011 decreased its fleet size, by 0.35%. The United States Postal Service by far has the oldest federally owned fleet on the road, with an average age of 16.3 years, more than double the age of vehicles owned by other federal agencies. E-85 flex-fuel vehicles are the most common types of vehicles purchased in 2011, consisting of 45% of total acquisitions. In comparison, regular gasoline vehicles make up only 38% of total acquisitions.
