Just see what the manual has to offer. The bigest pitfall in taking Transportation Depth is not knowing all the manuals and what are they used for. There is a post somewhere in Transportation where "csb" has posted what each reference book can be used for in the exam. I think that is an excellent resource, especially for those who don't use these books on a regular basis.
Here's the link to the topic I referred above. http://engineerboards.com/index.php?s=&amp...t&p=6662106
