NASCAR driver Bubba Wallace was booed during a recent race, and some in the crowd reportedly cheered when he crashed his car.

Wallace, NASCAR’s only full-time black driver, was met with some hostility during Wednesday’s qualifier in Bristol, Tennessee. The race was the first with a sizable number of fans since NASCAR’s decision to ban the Confederate flag from events. Jenna Fryer of the Associated Press wrote on Twitter that the No. 43 driver was booed by fans.
