What's all that blue stuff? After days of rain, Charlotte Motor Speedway was bathed in sunshine. And that means it's race day.
Saturday's storm caused by Hurricane Matthew's backwash left only mud and puddles. But for racing, the biggest impact was a green racetrack. So, NASCAR ordered a competition caution after 25 laps in Sunday's Bank of America 500.
Green flag was scheduled to fall at 12:05 p.m. ET, when Kevin Harvick leads the field into the first of 334 laps.
All cars cleared inspection before driver introductions, although Matt Kenseth needed adjustments to get through the process.
