The NHRA resumed its season Saturday in front of an expected crowd of 3,000 to 4,000 at Lucas Oil Raceway in Indianapolis.
Fans were not allowed at Friday's practice session but returned in a limited capacity for qualifying. NHRA president Glen Cromwell said ticket sales were capped to less than 15% of normal capacity.
Fans also are expected to attend Sunday's finals.
Most fans wore face coverings -- complying with county guidelines -- and observed social distancing in the stands, pits and at concession areas.
John Force Racing did not attend the first of two consecutive weeks of activity in Indianapolis.
