Training Guide Mistake

I think that question in particular is common sense. The question isn't trying to ask you specifically how many feet it is to stop a truck but it's probably trying to see if you understand the difference between feet and yards.

A truck going 55mph is going to take a heck of a lot longer than 35 or 100 ft to stop but isn't going to take 450 yards or over 4 football fields that's ridiculous.

So there's only really one answer that makes sense. :)

Exactly, but the correct answer was 450. Nowhere did it say anything about 450 feet. I am just pointing out that when you click the thing that says click here for the answer. On some it doesnt give the answer.

the stopping distance at 55mph is more than 300 feet and increases at higher speed.

I'm not sure what you are saying?

So what is it you are saying is wrong? The parking brake on truck is the yellow diamond. The trailer supply is red octagon....the stopping distance at 55mph is more than 300 feet and increases at higher speed.

I think he's saying that the link that's supposed to take you to the section of the manual with the answer, doesn't.

Well, the correct answer was the top anawer according to this website. That is why i thought they messed up and put trailer instead of tractor. I just have another confusing question about and. Asking where the malfunction light was. The 3 of the 4 answers I could chose from were technically correct according to the manual. The answers were left side, front, back and right side. According to the manual it's on the left side at the front or back, but it was flagged as wrong when I picked left side and correct answer was supposed to be front. I understand it takes a lot to get this website running and keep it running. I am by no means trying to be an ass or anything. I am just trying to help correct some of the mistakes for people who may need to use it for their CDL. I truly appreciate all the work the admins of the site have put into it. It has helped me a lot so far.

If I am not mistaken. Shouldn't this ve Tractor Protection Valve and not trailer protection valve?

I think the answer is the emergency spring brake valve (red knob), but I agree that it's not clear from the section in the manual.

Oh, ok, if "trailer protection valve" was the correct answer, then you're right, it's a mistake, it should be tractor.

On this one I wasnt sure of the answer. So i clicked on the find the answer link. Then after reading the part of the manual that was supposed to have the answer. I figured it was a typo on the question and it meant added stomping distance since 32 feet was an option and it was also in the part of the manual that supposedly had the answer in it.

I'm not sure what you are saying?

I think you're right. As someone said above, the federal government put out a 'model' cdl manual, and so most state manuals are almost identical. But states can make changes, and for some reason they seem to like to change the stopping distance calculation. I live in Maine and our manual is different in that section. I don't know, maybe it was a correction that only some states adopted. Anyway, here's that paragraph from the Indiana manual:

Perception Distance + Reaction Distance + Brake Lag Distance + Braking Distance = Total Stopping Distance The air brake lag distance at 55 mph on dry pavement adds about 32 feet. So at 55 mph for an average driver under good traction and brake conditions, the total stopping distance is over 450 feet. See Figure 5.6.

If I am not mistaken. Shouldn't this ve Tractor Protection Valve and not trailer protection valve?

The red knob is the emergency spring brake valve in that particular question.

Country this is great to start putting this in your mind to remember but when you go to school they will teach you on that states specific test. As long as you study you will pass it in roughly 3 days.

After someone said stopping distance . At vary. I looked at my state book that I downloaded as pdf file. Luckily my book has same stopping distance. It's word for word on what's on here about 32 feet and 450 and all that.

One other question i have though. So far I have made it to around page 56. I just finished coupling and ubcouplibg and the next section is doubles and triples. I have already study everything before that. So i should know what i need to for ait breaks, combination vehicle and general knowledge right? Or will log book question be on general knowledge? I am just trying not to flood my mind with unnecessary stuff at the moment until after I get my cdl permit. Then i can always go take test for endorsements right? Or do i have to do it all at same time?
