Rand-McNally Motor Carrier Road Atlas, GET ONE!

Amazon.com

This is the second most important book in the industry. In one book it lists the truck restricted routes, low clearance locations, weigh stations, mileage guide, phone numbers and web sites for each state's highway patrol, permit office, DOT, AND maps. While it's $30 at Amazon for the newest version they are often available for $15 toward the end of the current year and at EVERY truck stop. If you don't have one, get it. Almost ANY ticket you get will be much more than $30 and EVERY ticket for taking a truck on a restricted route will be MUCH more than $30.

I would not recommend the big laminated (expensive) version as the gap between the left page and the right page are huge and in some states the most important part of the state is in the middle of their map page. Also, being so big and so heavy, you won't keep it easily available from the driver's seat. You also won't replace it often since it's 2-3 times the price of the paper version. Trying to use the laminated version while driving will eventually wear out the pages you use most and they will fall out. Ask me how I know.

If you don't have and use this book you don't want to know how to stay out of trouble. No, it will not navigate you from 123 Main St, East Toad Slime, Oregon to 15 Maple St, Crying Baby, Arkansas with turn by turn maps. That's what your truck specific GPS is for.
