Doubles/Triples Endorsement

Load to route is still the best way for LTL.

 

My company phased out doubles because their analysis indicated the extra tires, maintenance on doors, airlines, etc did not justify their use.

 

Yep more moving parts and easier to flop. The extended weight trucks are going to 8 axle 53 semis instead of the 40/20. However in certain jobs the combinations are still used. Like LTL or gravel trucks,ect.

 

The doubles/triples practice tests on the front page of this site are pretty thorough. Most of the questions were almost identical if not word for word when I took the rest.

Which reminds me, I'll be due to renew my hazmat soon. Time to start taking advantage of the free resources offered.

 

Study, study, study. As I remember, the doubles/triples questions that were "HARD" revolved around dollies and air-line connections.

Learn dollies.

I did this by going to a local SYSCO about 2 miles from my school and asking to be "schooled" by an experienced driver. He was nice as could be and thrilled to answer my questions.

Practically, NO ONE is going to hire you right out of school to drive doubles/triples. *I* certainly wouldn't. Nice to have on your CDL, but not a big deal as anyone hiring you is going to "SCHOOL" the HECK out of you before they stick you with one. Also, they drive EASY. Back trailer follows the first one. Basically ZERO offset. BACKING a double...well, just DON'T. Not more than 10 feet. You shouldn't even NEED to.

 

You can thread a set/train (3) in town easily. If you get ummm stuck break them up.
