As 2022 rolls in, we can reflect back on what the previous year had to offer. Let's take a look at some of the collision industry information you've been most interested in from this past year. These are the most popular articles from 2021.

The most popular article titled Pre- and Post-Repair System Scanning Statements was published in January of 2019 and made our top 20 list this year and previous years. This article is a compiled list of I-CAR's Repairability Technical Support (RTS) articles that highlight OEMs that have a pre- and post-repair system scanning position statement, and how to find them. In addition, there is information on the Automotive Service Association (ASA) and Equipment and Tool Institute (ETI) position statements as well.
