Will 392.15 put my truck out of service?
Yes, almost certainly. Across our inspection records, 392.15 citations result in an out-of-service order 98.7% of the time—1,476 out of 1,496 all-time citations led to immediate placement OOS. This is dramatically higher than the all-FMCSR average OOS rate of 31.4%. When an inspector finds that you're in the Drug and Alcohol Clearinghouse as unable to perform safety-sensitive functions, that violation is treated as an immediate compliance issue, and your vehicle will be removed from service until the underlying clearinghouse matter is resolved.
