In the 2016 season, the Truck Series experimented with a rule similar to those used in longer-distance Super Late Model events such as the Snowball Derby that limited how long a race can go before a competition caution for pit stops or adjustments in an effort to reduce green-flag pit stops, which younger and more inexperienced drivers were not familiar in doing. The limit was 20 minutes of green flag racing (in theory 75 laps at Bristol, or 60 laps at Martinsville), without beneficiaries being awarded. Upon each restart, the clock restarted from 20:00, and each caution for an incident reset the clock back to 20:00. As is the case in the short track rules, no competition caution would be used in the final 20 laps, except for tracks where lap times are 50 seconds or greater (Pocono or Mosport), where the limit was ten laps, or Eldora because of its format. In 2017, it was replaced with the stage system adopted by all other NASCAR national series that season.
