will 393.76(h) put my truck out of service
No. Across our inspection records, the 0.0% out-of-service rate for 393.76(h) means this citation never results in an OOS placement. All 3 citations on record were issued without removing the vehicle from service. This contrasts sharply with the all-FMCSR average OOS rate of 31.4%, making sleeper berth equipment defects one of the least enforcement-intensive violations in the vehicle maintenance category.
