NASCAR has penalized four Craftsman Truck Series teams for safety infractions at Darlington Raceway and Kansas Speedway.

Each of the teams was penalized for the same infraction related to use of the driver’s side window net, a critical piece related to driver safety. Window nets cannot be used two years after the date of manufacture.

Penalized for Darlington infractions were the G2G Racing teams of drivers Brennan Poole and Dawson Cram. The Young’s Motorsports teams of drivers Spencer Boyd and Nick Leitz were penalized for Kansas Speedway infractions.

The crew chiefs for each team — Daniel Killius (Cram), Timothy Silva (Poole), Bradley Means (Boyd) and Joseph Lax (Leitz) — were fined $5,000 each. The teams were penalized 25 points each.
