Hidden in Plain Sight
During a recent inspection at the Desert Hills Commercial Vehicle Enforcement Facility, CHP officers stopped this loaded tractor-trailer and discovered one of the two fifth wheel pivot bracket pins was missing.
The pivot pins retain the fifth wheel head on the tractor, ultimately connecting the trailer to the tractor. With one pin missing, the fifth wheel assembly is no longer properly secured, creating the potential for a catastrophic failure resulting in trailer separation.
Because of the severity of the defect, the vehicle was immediately placed Out of Service and remained out of service until repairs were completed per 49 Code of Federal Regulations, section 393.70(b)(1)(i) - CVSA Out of Service Criteria.
This is a reminder why thorough pre-trip inspections matter. Many of the most dangerous defects aren't obvious until someone takes the time to look closely.
For comparison, a video of the opposite side was included to show what it should look like...
Would you have noticed the missing pin before the camera zoomed in? 👀
