Pre Trip Inspection

[SevenOfNine]

The Pre Trip is extremely important, so try not to take the attitude that you are being forced to learn it for the sake of passing a CDL test.

The importance of the Pre Trip carries far beyond the plastic. Learning to spot potential equipment failures and problems ahead of time may save your life and someone else's - as well as extend the life of the equipment and/or save you a stay and/or a fine at the DOT scalehouse.

Your school may have a different way of teaching you to perform a Pre Trip. The following is intended for reference only.

1. OIL LEVEL - check and mention, in safe operating range

One more important thing to pay attention to is any damage noted on the tractor or trailers, if so get it noted and have a supervisor/dispatcher look at it and have them sign it off on the v.i.r., it could really save your butt, job ,safety record or what-ever.

[Fifth Wheel]

That's good advice when you go to your
new company but not required for school. It is in our carrier prep class for students as well as what they should remember to take with them. I'll grab the list at school and post it.
Kermit writes some pretty good stuff for the students. You'd think she was their
keeper the way she protects them. Hell I saw her run a recruiter right out the front gate cause she caught him telling a student a lie! I laughed till I hurt.
