For the 2013 season, Herring ran six races for JGR, posting two sixth-place finishes and had only one DNF due to a crash at Bristol Motor Speedway. After not running any races in 2014, he qualified as a stand-in for JGR twice in 2015, but did not run a single race. At the same time, Herring became a Toyota Racing Development test driver, often testing experimental setups for NASCAR Cup Series cars.
