First off you need to really relax try and stay as calm as possible this of course comes with experience though the more confident you become the more at ease you'll feel. The key here is your instructor should know if you are ready or not, and whether to go ahead and book a practical test with the DMV. Pay attention to what ever they say as their the experienced ones by all means ask questions if you don't understand something. One place I used to work at had a slogan it said " Its better to ask a silly question then to make a stupid mistake", most important hang in there sometimes people quit when their so close to actually achieving something.
Bad training experience. Dangerous?

To those who believe 'coasting' is bad (and I guess even illegal?), I was just reading up on automated manual transmissions. My interest in the topic was fuel economy, not fear of using a manual. Here's some boilerplate describing a Daimler/Detroit automated manual transmission:
<<The ECOAST mode automatically disengages the transmission when traveling downhill. As a result, engine RPMs will drop, momentum will be maintained, and fuel economy will go up.>>
Sounds like this is 'coasting.' If so, it means it's illegal, and bad, if a human does it, but perfectly acceptable if a computer operating the same manual transmission does it.Gearjammin' Penguin Thanks this. -
It's the 34 cents BS you will avoid. -
I will NEVER operate a automatic without a manual gear function and NEVER operate a auto that thinks it need input from satellites or god knows what else to do something different than what I want it to do.
If I had a foot, I would drop kick that over teched POS over the moon.
There have been way way too many times where constant power to the drives either maintaining speed, pulling or jacobs braking made all the difference in safety. Yes I played nuetral over drive down grade for laughs once or twice. Gravity speed tops at 145ish my math isnt that good against the stop watch between yardsticks that fast down a 5 mile 6% in nuetral. -
I HATE ecoast. I do not feel safe most times when it kicks in.
I HATE how the AMT transmissions downshift to a stop. I have to use my brakes more and it increases the time/distance to come to a safe stop.
Going back to the mirrors - I have told some of my students not to adjust the convex mirror. They want to adjust it in so they can see more of the trailer as opppsed to what they should be seeing - the road next to them. I have also made my guys adjust the west coast mirror out . I only do this after they have trouble staying in their lane or getting straight in a hole as these are indications that the mirrors are not set correctly.x1Heavy and Sirscrapntruckalot Thank this. -
Let us now where your location is? State & nearest city.

Now, should the instructor teach the student the correct way to downshift and engine brake in order to slow down and/or come to a stop? Absolutely. By all means. But is the appropriate time and place while the rookie student is barreling down the barrel of a busy intersection or someone's rear bumper? No.
As to a jackknife scenario, just thinking logically about it, and thinking about the physics involved, downshifting and engine braking would put more braking power on the tractor wheels (engine PLUS brakes) than the trailer would have on its wheels (brakes alone), so it seems to me that if anything, engine braking plus normal brakes actually has more potential to jackknife the trailer vs. just straight applying the brakes to everything. I'M NOT SAYING YOU SHOULDN'T USE ENGINE BRAKING. You should. But if you are saying that just straight applying the brakes has more jackknife potential than brakes plus engine, I'd like to understand how that is the case.
Oh, as to mirrors and your students wanting to adjust them to see all trailer, I wanted to adjust them to see LESS of the trailer and more of the road and situation around me. My instructor forced me to keep them where all I could see was trailer, blue sky, etc.Last edited: Feb 1, 2019

Do you want to know so you can warn others away from this place? We can talk privately, I guess? And I love the asian theme, BTW. If that is you in the pic, you did wellGood job!

I have had many circumstances like you describe where I have told my guy to grab a gear after he dumped it unto neutral. There was plenty of time - if he did as instructed. As an instructor, if I am telling you to do something, it is the safe or easy way to do it. It is a skill you need to learn , he thought you had time to at least make an attempt, so make the attempt. When I got my cdl my instructors did plenty that I didn't like. I figured out WHY they wantedme to do it that way AFTER complying with their instructions.
There are 6 brakes on a tractor, 4 on the trailer, thus when hitting the brakes hard, the tractor will slow faster than the trailer . An experienced driver can feel the trailer pushing in hard brake scenarios.
I can tell you what my experiences have been over the last 8 years of training and you can glean some valuable information. However right now it is not sounding like you are trying to learn from people on here, but looking to vent or for sympathy. I wish you the best, but I'm done.
