will 180.207(b) put my truck out of service
No. Across our inspection records, 180.207(b) citations have resulted in a 0.0% out-of-service rate—none of the 3 all-time citations in our database led to an OOS placement. This is significantly lower than the 31.4% average OOS rate across all FMCSR codes. However, compare this to peer hazmat violations: general loading violations (177.834A-HMC) carry a 99.2% OOS rate and general loading (177.834(a)) has a 97.9% OOS rate. Your citation alone likely won't ground your truck, but the specific violation and inspection context matter.
