This document describes an analysis of Arizona IM:240 data collected from the state I/M lanes during the second half of 1995 and the first half of 1996. It includes full 239 second initial test results from more than 16,000 cars and light-trucks. Retests on failing vehicles using the full 239 second test are also available. The analysis focused on vehicles which were initially tested during the 1995 calendar year to increase the number of failing vehicles which could finish the I/M process in 1996. This produced a total useable sample of about 7,650 vehicles.
