300 support races were the first to admit paying spectators, as backstretch campers were allowed to stage on track to watch all three races. NASCAR procedure would be only Cup Series races would have grandstands open, while support series races would have selected camping areas (initially outside the circuit overlooking the circuit, but later adjusted at some races to allow selected infield campgrounds) open. On 3 July, Jimmie Johnson reported that he had tested positive for COVID-19 (the first NASCAR driver to do so), requiring him to use Justin Allgaier as a substitute driver for that weekend's Big Machine Hand Sanitizer 400. That turned out to be crucial, as Johnson, who had been scheduled to start sixth, would miss the playoff cut by six points. Johnson was asymptomatic, and was cleared on 8 July after two further tests came back negative. On 15 August, Austin Dillon became the second Cup Series driver to reveal a positive test, and as a result he missed the Daytona Grand Prix. Unlike Johnson, Dillon had already secured a playoff spot by winning the O'Reilly Auto Parts 500 at Texas the month before. On 8 July, NASCAR announced the remaining schedule of races through the end of the regular season in late-August, including twin races at Dover International Speedway and Michigan International Speedway (both held on their regularly scheduled dates, but with a Saturday rescheduled race each) that would both be 500-kilometer races, and the race at Watkins Glen International being replaced by inaugural road course races at Daytona due to New York state travel restrictions. NASCAR stated that more upcoming races may be held with spectators on a case-by-case basis depending on local health orders, with Texas Motor Speedway (50% capacity for Cup only in grandstands, backstretch camping open for all races), New Hampshire Motor Speedway (19,000), and both Daytona races (about 20,000 for Cup only, some infield camping was allowed) planning to do so. Of these races, Kansas, Dover, and Michigan were held behind closed doors. The 2020 NASCAR All-Star Race was held at Bristol Motor Speedway on 15 July instead of in Charlotte so that it could host limited spectators. Twenty-two thousand spectators attended of a potential 30,000, or approximately 20% of the venue's total capacity of 162,000, seats available. It was the largest number of spectators at any U.S. sporting event since the beginning of pandemic restrictions. On 6 August, NASCAR
