Penski I think I spelled it correctly, does not use psp but rather your mvr

Ah, so close, it's Penske, and seemingly a good company. Employees give it a "3.8" out of a "5". Been around a long time, so I doubt they would do anything shady like that. This has been discussed before here, hope this helps.
Dispute PSP report

 

I am curious about this, from the FMCSA website, data comes from inspection and crash history, I do not see where carriers can add information to a PSP report at will. Can you provide some insight on how a carriers can input their own data?

From the FMCSA website:

A PSP record contains a driver's most recent 5 years of crash data and the most recent 3 years of roadside inspection data from the FMCSA MCMIS database. MCMIS is a federal government database, which is different from the state data sources used to generate Motor Vehicle Records (MVRs).

A PSP record displays the motor carrier for which the driver was operating for at the time of the crash or inspection. It also shows the location and date that a crash or inspection occurred. Additional safety details about crashes such as injuries, fatalities, and towaways are included in a PSP record. Likewise, inspections show details like whether a vehicle was placed out of service.

Following a request for data review, a PSP record may be updated to reflect a determination that a crash was not preventable, or to note that a driver was convicted of a different charge.

The PSP record does not contain a score.

The record displays a snapshot in time, based on the most recent MCMIS data load into the PSP system. A new snapshot is uploaded approximately once per month. ​

 

From my experience with them. Penske has trash elogs. Because once I was in one of their rentals. Elog was on my phone. Disconnected from the truck by stepping 5ft away.

When I was at Southern Pines Trucking. Maintenance went through Penske. Took forever for anything to get done. Actually one location didn't have the tool to connect to a 2023 579 Pete to diagnose a issue

 

Well, I don't know about the elog issue, but maintenance problems pretty much affects all outfits. A dire shortage of mechanics, overwhelmed by todays BS in trucks, and I don't think Penske specific. Besides, a 2023 Pete with an issue? It would be sitting on the dealers driveway with 10 flat tires,,,
