Will 393.209C put my truck out of service?
Yes, most likely. Across our inspection records, 393.209C citations result in an out-of-service order 88.6% of the time. That's far higher than the all-FMCSR average of 31.4%, making this one of the most serious steering defects inspectors cite. Of the 149 all-time citations in our database, 132 trucks were placed out of service immediately. You will not be allowed to operate the vehicle until the steering column is repaired and reinspected.
