will 396.11(c) put my truck out of service
No. Across our inspection records, 396.11(c) citations have never resulted in an out-of-service placement. The OOS rate for this violation is 0.0%, meaning trucks cited for failing to repair defects noted on the DVIR before dispatch remain legal to operate. However, the underlying defect itself—if serious—may trigger an OOS citation under a different code. Address the defect promptly to avoid secondary violations.
