NASCAR issued only one penalty following the race weekend at Sonoma where a loose lug nut was discovered on Austin Hill’s No. 21 car after the Xfinity Series race.
Andy Street, the crew chief for the No. 21 Xfinity Series car was handed a $5,000 penalty for having a lug nut or lug nuts improperly placed after the DoorDash 250 on Saturday at Sonoma Raceway.
A lug nut that was not secure during the post-race inspection resulted in NASCAR issuing a penalty to the No. 21 Richard Childress Racing Xfinity Series team. Crew chief Andy Street received a $5,000 fine from the governing body as a result.
This was the only infraction from either the Xfinity Series or Cup Series races at Sonoma.
NASCAR referenced Sections 8.8.10.4a of the Rule Book as part of the penalty imposed to Richard Childress Racing on Monday, which addresses tyres and wheels and mentions improperly placed lug nuts.
Austin Hill, who is now second in the series standings, finished the DoorDash 250 in eighth place while driving the No. 21 Chevrolet.
Nashville Superspeedway will host the next Xfinity Series race on June 24. (3:30 p.m. ET, USA Network, PRN, SiriusXM NASCAR Radio, NBC Sports App).
