The average age of automobiles was lower than the average age of trucks until 1995. Since then, the average automobile age continues to grow, while the average truck age has held about the same. The increasing popularity of light trucks as personal passenger vehicles may have had an influence on the average age of trucks.

3–12 The average age of trucks (classes 1-8) has historically been higher than the average age of automobiles. In 1995, however, this trend reversed, with average automobile age higher than average truck age for the first time. The recent boom in the sales of minivans, sport-utility vehicles, and pickups, which are classified as trucks, is influencing the average age of trucks. So many new light trucks are being added into the truck population, that the average age of trucks has been declining since 1993, while the average age of automobiles continues an upward trend.
