Preventable are a corporate way to punish those who scrape and break something that could have been avoided.
Lets say you racked up ... three preventables in 6 months. You are dismissed from employment for cause, DAC, Hireright etc are plastered with the damning details against you by your employer and all future employers refuse to hire you because you have too many accidents. You are then out of the industry for a minimum of three years. IF not also blacklisted.
You will still have a CDL and all that but since you are no longer ACTIVELY WORKING, you will need to go straight to your DMV and sign a Tier Two Document sworn to keep your CDL at a lower level and not working. That way it does not get downgraded when your DOT medical expires among other things.
Its a behind the scenes way of the industry, as in trucking companies to keep out the riff raff who constantly break stuff. Big and small. Whoops I hit it boss, Broke a mirror. PREVENTABLE. Whoops I was 10 minutes late now walmart wants a week before I come back with load. PREVENTABLE. WHOOPS I went 70 mph down Fancy GAP... PREVENTABLE.
Then fired. Gone. Finished. Wonder what happened? Thats what.
Never mind the political sound and fury over truckers being shortage. Its outdated practices that eliminate mostly newer truckers because companies no longer tolerate a certain cost incurred while they dent and scratch stuff learning how to be GOOD drivers that can back onto a wine case without shattering the glasses inside.
I had a famous preventable that cost me two years of 'splaining to future employers. A thousand dollars worth of curved curbing was destroyed in the Sayre NY VA Clinic then under construction. I put he spread axle with a load of tamko shingles for them into that lot and the curb was run over and destroyed. Thats a preventable. And a big one.
The good news is that the replacement curbing is still there as is the clinic to this day.
Never mind the 15000 dollars in inventory I destroyed once in Milldale during 2000 when wife and I got trapped on their property trying to get out. That was no big deal in comparison.
