Cnemidophorus sexlineatus can be found in prairies, dune edges, oak savannas, riverbanks, abandoned fields, vacant lots, and road cuts. Road cuts normally provide plentiful basking sites during summer and are less likely to freeze during winter. These lizards avoid shady forests but will inhabit open woodland. Six-lined racerunners have a relatively short activity season, since they can lie dormant for as many as nine months in a year. Generally, however, their activity season is four to five months. Adults tend to be the most active in June and July while juveniles are more active from August onward.
