Will 393.60(b) put my truck out of service?
No. Across our 13 million inspection records, windshield tinting violations result in an out-of-service order only 1.2% of the time. Out of 670 all-time citations for this code, just 8 trucks were placed out of service. Compare that to the national average OOS rate of 31.4% across all FMCSR codes—this violation is far less likely to sideline your truck. You can typically continue operating while you arrange a fix.
