those pup duble trailers are the same kind i ran out to lodi oh with a sleeper cab tractor-so that photo shows a singal axel mack day cab-so this most likely means thats a LTL RUN,meaning that a highly sought out job by r and l drivers because you get great pay and are home almost every day or night,you run like to the end of nj and do a swap out with anthor r and l driver,the dangerous thing is you get high pay at r and l because you run some of the most dangerous hazmat loads that can be hauled on a tractor trailer,the plac cards in the photo i can not see any hazmat marked on the rear trailer,its hard to tell,any ways tath driver could have killed alott of drivers on the highway,and if it was hazmat even worse,they should think about keeping the more exp drivers happy,and and a keeping a steady job with them--i would also like to say the wallingford ct terminal does have a great DISPATCHER--WHO KNOWS HIS STUFF,AND HOW TO keep drivers happy and productive,as well as the guy who takes you on the road test and 2 day training runs i think his names JIM-who drives the chevy colorado pick up ,hes cool as well.
