will 392.2-RKD put my truck out of service
No. Across our 13 million+ inspection records, 392.2-RKD has never resulted in an out-of-service placement. The OOS rate is 0.0%, meaning every citation on record allowed the vehicle to continue operating.
That said, reckless driving is a serious violation with a CSA severity weight of 10—the highest category. Even without immediate OOS consequences, it will damage your safety profile and trigger carrier or insurance review.
