will 393.116(c) put my truck out of service
Yes. Across our 13 million inspection records, every single citation for 393.116(c) resulted in an out-of-service order—a 100.0% OOS rate. This is far stricter than the national average of 31.4% across all FMCSR codes. When an inspector finds an intermodal container not properly secured to your chassis, your truck is not moving until it's fixed.
