Multiple NASCAR Cup Series teams faced penalties this week stemming from pre-race inspections at both Darlington and Las Vegas. At Darlington Raceway, three teams, including notable entries from Hendrick Motorsports, failed inspections twice, resulting in the ejection of their car chiefs. Chase Elliott, in particular, was hit with a double punishment, losing a crew member in addition to team penalties. Similar issues arose in Las Vegas, where four teams were penalized after failing pre-race inspections, leading to the ejection of four additional car chiefs. This series of inspections has highlighted ongoing compliance challenges within the NASCAR ranks.
