Bruce Brandon (defendant) worked as a pipefitter for A.R.B., Inc. (A.R.B.) (defendant). Brandon was working on a site to which there was no public transportation, requiring him to drive. Because the employees were required to drive to the site, A.R.B. paid them a daily travel allowance to compensate for using their personal cars. One day, Brandon offered to drive a coworker, Richardson, home after work. On the way home, Brandon got into a car accident with Caldwell (plaintiff), causing Caldwell injuries. Caldwell brought suit against A.R.B. and Brandon. A.R.B. filed a motion for summary judgment, arguing that Brandon was not acting within the scope of his employment at the time of the accident. The trial court granted the motion. Caldwell appealed.
