Great app for highway users!

We are fulltime RVers and often while riding down the road we wonder "Whats in that truck". Before buying theHazMat Reference we had to hope we had Internet connectivity, start up the browser, search on the placard number and find the appropriate information. Now we just type the placard number into the app and we immediately know what were sharing the road with. Highly recommended even if only to satisfy your curiosity.
