I've been a class B driver for 10 years now and I've been trying desperately to find a company in my area that would train me for my class A. Last year I finally caught a break and got hired on with caltrans (that agency you all know and love)
I got my class A permit back in January and I've been driving whenever I can. When you think you are ready they will send you to a one week program in Sacramento that will make sure you're ready for your pre trip, skills test and driving test.
Well today I took my test and I passed!! I finally accomplished my goal of getting my class A!!
