Phoenix Spring Race: Cautions

All eyes are on Phoenix this week, not only for the spring race, but also to glean clues as to what we should expect in terms of cautions and lead changes when we return in November for what is now the championship race.

Phoenix is a relatively consistent track. Today, we’ll look at cautions.

A column chart showing cautions at Phoenix International Raceway
  • The most cautions in a Phoenix spring race is 10 (2015)
  • Three races had nine cautions: 2005, 2010 and 2019 – see the note below about why 2010 was an unusual race.
  • The lowest number of cautions in a Phoenix spring race is 5 (2016)
  • The average number of cautions for a Spring race at Phoenix International Raceway is 7.6. The introduction of stage racing in 2017 hasn’t changed that number.
  • In addition to the two stage cautions, expect between three and seven additional cautions, with four to six additional cautions most likely.

Caution Laps
