Understanding Segragation tables for Hazmat test - or any table?

Hello. I'm studying to take the Hazmat and I'm a little confused about the compatibility table. Actually I find the entire topic of navigating all the federal code references difficult because there's so many and in different revisions.

Maybe I'm concerning myself with information I don't need for the test at this stage? The study book I got from the DMV is not explaining things very well. Like for example what is this strange symbol --> §?
Also, I understand this far that hazmat classes have numbers 1 though 9 and then there are sub divisions, but then then the book displays a compatibility table under the segregation table which has letters. (see attachment) What are these letters for? I thought classes were displayed as numbers and divisions? I'm not finding anything in the book that's even talks about these letters in the compatibility charts. How do carriers even know how to read this stuff? I would like to learn. And the DMV 2013 Study book is not really helping.

Advanced Thanks

 

My soul is still back in Illinois where I've lived my entire life. looking at how strict CA has been on registration, healthcare, ect I really miss Illinois. I miss the easy flat land driving.
Anyway, thanks for the info on the General Statute. I was googling this strange looking thing § and nothing was coming up. Thanks chicknwing.

Hello pattyj.
Well, the procedures and general rules in the hazmat section of the book are not that difficult. But if you don't understand navigating the charts (how to verify what can legally be transported with what) you can read it over and over but you're not going to retain what you don't understand in the first place. I'm thinking some of this stuff you learn on the job. On the other hand they might test on it. The state obviously wants people to know about it because it's mentioned in the book, yet they don't give good examples so people can learn it. I mean, I still don't know what these A, B, C.. ect classes mean. At the beginning of the Hazmat chapter it said there are classes, 1, 2, 3... through 9. Now all the sudden it's talking about classes being named as letters with no explanation what the letters pertain to. I wouldn't even know how to check if something was legal or not. It's funny, the state won't take the time to produce a book that makes sense, but they have no problems giving out tickets when people don't understand. I'm starting to think governments want us to be ignorant so they can make money on fines.

EDIT
I didn't see your post when I typed this TomOfTx. Thanks for responding by the way.
Ok, so they're Class 1 explosives. Makes sense. That chart is more helpful. Why couldn't the DMV put that in the study book.
I still think all these charts are confusing. Where to look for different things and then there's more then one chart for many of the same chemicals while other charts sometimes don't list all the chemicals. It's makes it difficult to know where to go to find all the information. I just hope I'm not tested on these charts, and that I'll learn these tables on the job. I don't know.

 

Maybe a silly question but, if I were to walk into a CHP, California Highway Patrol office on the road, do you think they could explain any questions I have?
I mean how informed typically are state police on this stuff?
