NASCAR fined three crew chiefs in the Cup Series and four crew chiefs in the Xfinity Series for safety violations in last weekend’s playoff races at Las Vegas Motor Speedway. Each team had one lug nut not safe and secure in post-race inspection, a violation of Sections 10.9.10.4 in the NASCAR Rule Book.
