will 172.201A3 put my truck out of service
No. Across our inspection records, the 0.0% out-of-service rate for 172.201A3 citations shows that inspectors do not place trucks out of service for this violation. This stands in sharp contrast to the all-FMCSR average of 31.4% OOS rate, and dramatically lower than related hazmat violations like general loading/unloading defects (99.2% OOS rate) or placarding violations (75.1% OOS rate). You will be cited and assessed CSA points, but your truck will remain roadworthy.
