What does PMS stand for in a CDL context?

In the context of CDL and vehicle inspections, PMS stands for Properly Mounted and Secured. This term is essential during pre-trip inspections because it emphasizes the importance of ensuring that all components of the vehicle—such as the engine, transmission, exhaust system, and any other parts—are correctly attached and stable.

When a vehicle is properly mounted and secured, it significantly reduces the risk of mechanical failure or accidents caused by loose parts during transportation, enhancing safety on the road. This concept is a vital aspect of the responsibilities of a commercial driver, as it ensures that the vehicle is in a safe and reliable condition for operation.

The understanding of PMS is critical for students preparing for their CDL, as it lays the groundwork for conducting thorough and effective vehicle inspections before embarking on any journey.
