Thanks for the input guys. As to getting the CDL A without a school I know where you are coming from. The good news, for me anyway, is that I already have a job.....all I need is the license. Insurance and everything else is squared away. I do imagine it would be difficult to get a job at a trucking company without coming from a school.
kc0iv - Your suggestion is excellant. I took the Highway Watch on-line course. I had my membership number before I took the written exam. It is an interesting course and has made me more aware while I am driving.
Douglas - by dimensions I mean the layout of the skills course at the DMV. It looks like the lanes are a certain length, the pull up line is a specific distance from the end of the lane and so on. Also, how wide and long is the parallel parking space.
Again, thanks guys for your input. I really appreciate it.
