I work for the park dept and found this site while studying for my class A. There is lots of useful infomation. So hello.

So, don't be bashful about asking any question you might have in the Questions from New Drivers forum: http://www.thetruckersreport.com/truckingindustryforum/questions-from-new-drivers/
