Best in cap inspection I’ve ever watched! Really going to watch this over and over to prep myself before I go to school💯

Looks harder than what it seems. I have to pass it and practice makes perfect right . Great job!

Thank you so much Mr. Butler, it has been hard for me to pass my pretrip inspection test, I am as old as the wind, words come and go without staying in my head, but, you make this very simple and easy to remember step by step, so, I will go and take the test this time and hopefully the DLI will approve me this time.

Thank you so much for this video!!! I am watching it over and over again! ty ty

Thanks for your explanation is very clear and understanding .God Bless you my Teacher.

Great explanation 🙌

great lesson! well organized and clearly flowing in order, and text explanations added , Thanks a lot!!

Thank you. I needed that refresher. Very clear and understood all the way through.

Mr. Instructor, your lesson is spot on! I'm so happy I found your YT channel! - How about "Steering wheel has less than 2 inches of play on a 20 inch wheel" /

Thanks, started truck driving school two weeks ago, love how you explained the in cab and brake inspection! Simple to the point! Some instructors want to over elaborate on the in cab and brake inspection!

This guy was very straight forward no extra bs, appreciate the video, very well done and very helpful

I start my new truck driving school in 2 weeks hope I do good.i watch videos like this trying to get ahead so i will pass,thank u for urs,god bless!

I really like this nice job. Will help a lot. Thanks

Very good air break test good instruction

very good instruction. Thank your Sir.

Great instructor

Watching b4 test tomorrow

Thanks for the video!!! Awesome!

thank you for the instruction

Gotta also check steering wheel play : less than 2'' on 20'' wheel. Also, probable should check compressor cut in......overall great job.

Thank you! So helpful 🙏🏾

Nicely done 💪🏾

Nice hat! 49ers all the way, Trey Area

Love that hat

Very helpful 👏👏👍

Not sure if you had the truck on, sounded like it was on during the air leak test. First time I went to take the test I failed because I had the truck on during the air leak test.

Is 10 degrees of steering wheel play still a check point?

So turn the truck off and bring it to on but dont start it right ?

I felt it was a good incab inspection my only question is the truck your using automatic or manual 🤔

I’m assuming he wheel chock the drive wheels before he started the in cab and air brake test.

Question?? Whenever you doing your Air brakes text, Do you keep your foot on the clutch? Or you dont have to?

Some things have changed which don’t need to be mentioned anymore since July & august 2023 pre trip Incab , Air breaks even outside too

Coal truckers in Kentucky don’t do any of this stuff some don’t even fill out the paperwork

You forgot about the break pedal and the gas pedal that's there's no loose part PMS not CBB and no more than 2 inches of play

The school that I signed up in gave me a reviewer for my pre-trip, in cab and air brakes. Should I need to memorize the whole script written on the paper and follow it words by words in exact order in my test day in front of the dmv examiner, or can I make my own script and with enough detailed explanation? The other thing surprise me I havent even start my training yet, but I am scheduled to the dmv within a month for the road test.

The only way to check whether the trailer breaks are working or not is roll the vehicle up to 5 miles per hour, then apply the hand break (aka trailer breaks) without applying the service brakes/ foot breaks, and the vehicle should stop.

Could this be used for California as well?

For the first 3 brake test. Leaks, low air warning and spring breaks. Why is your truck on ??? Book clearly read “ truck must be off “.

didnt check fire Ex is up to code and securely mounted

Thank you my instructors are ass there never here and when they are they end up disappearing for a hour or 2

for a safe start aren't you suppose to state that the primary air gauge is below 80psi and is good to do a safe start.

You said when you were performing the one minute break test , you put your gear on drive and then when you finish your test you took off your foot of the brake pedal 😧

Would of been handy if the in-cab inspection was a separate video. Air brake and most other aspects of inspections vary between countries.

DIDnt say anything about ABS lights and how to identify that they work.

When you start your truck there is already enough air pressure so how can you say I’m waiting for air pressure lol you have to let the air leave if you want to speak about the the the cab things

You might have a bulge on your windshield, check that again 😂

So no door and window opening and closing

Why check the phucking seals on door and winsheild? Not like that is on the test.

Great explanation although you FAILED!! You didn't chick wheels initially and why did you place gear in drive when doing the pump down test?

How come you didn't mention the height and the weight of the truck? I thought that was part of the incab inspection? I got point take off for not saying that, I guess it's different!

🙏🏿🙌🏿💯💯

low air alarm should be between 80-60 psi and buttons pop between 40-20 psi. And you don't give a diesel GAS, you give it fuel. fuel pedal, not gas pedal. Too bad he didn't have a manual transmission.

Omg

He’s definitely going to get a lot of people to fail. He didn’t even mention losing 3 psi

Horrible in cab. Jumping all over the place. Not organized

Sound is annoying

Did he really do the service brake test with NO HANDS on the wheel LOL!!! You are certainly still supposed to LIGHTLY hold onto the wheel absolutely positively 100%. Also, don't call the FUEL gas, it's not GASOLINE. It's diesel FUEL! It's not a "gas pedal"....

This was a mess

U didn’t even say ur seat belt was securely mounted on the truck just to start there u say things that don’t need to and the ones u need to u don’t say them
