I am renewing my Hazmat endorsment and recently posted a message asking for
links to Online CDL testing sites. Thanks to one of the newsgroup audience
they returned a link to http://www.cristcdl.com/otc/ . This is an excellent
resource for individuals who are getting or renewing there CDL.
I found questions there and in our State CDL manual that have helped me in
my studys. I am including them here for any of you who might need them.
Please try not to just memorize the following questions but use them as an
aid to your study.
Also, I am looking for some winter employment. I work in Alaska in
Information Technology and would like to drive the winter months (September
thru April) down south. I have a class A CDL Hazmat and have drove a lot.
Anyone have any ideas
Cheers,
