The first graph shows the rolling 12 month of U.S. vehicles miles driven.

By this measure (used to remove seasonality) vehicle miles declined sharply, and are set to slowly increase.

The second graph shows the comparison of month to the same month in the previous year as reported by the DOT.

As the DOT noted, miles driven in July 2009 were 2.3% greater than in July 2008.

Year-over-year miles driven started to decline in December 2007, and really fell off a cliff in March 2008. This makes for an easier comparison for July 2009.
