1. Low air
2. Flat tire, or my
3. Brakes are in need of adjustment
“That will conclude my air brake test and my in-cab inspection.”
This is fantastic! As a previous driver and now safety Director, I’m saving this.
Thank you!
really cool instructor. " proper mounted and secured" not broken loose or missing 😊
Alex is a great instructor
Very informative video, Jose. Thanks for sharing
Best explanation viedo ever
Auto fail..lol..thanks for the help..lol
Ok he needs to slow down a little hard to understand
To much crap to check.
Depending on the state it depends on what you check. Oregon has the easiest test whereas Washington and California have among the hardest tests. I believe North Carolina is the hardest. By hard I just mean the amount of stuff you have to say. A lot of states allow the school to test you whereas in Washington state, the DMV has testers that you must go through.
