6-10 I 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 increasingpopularity of light trucks aspersonalpassenger vehicles may have had an influence on the average age of truck.

I Using current registration data and a scrappage model by Greenspan and Cohen, [ 1996 paper: http://www.bog.frb.fed.us/pubs/feds/l996~199640~19964Opap.pd~, ORNL calculated new automobile scrappage rates. The expected median lifetime for a 1990 model year automobile is 14 years. These data are fitted model values which assume constant economic conditions.
