Ever see a big rig hauling two or even three trailers and wonder how
someone handles something that massive? Or maybe you’ve seen it and thought, “I
want to be the one driving that.”
You’d think the to-do list to get the endorsement would be as long as a
triple trailer — but if you already have your CDL, it’s a pretty simple
process.
(Don’t have your CDL yet? Check out this post to get started.)
- A valid CDL
- The required forms and fees for
testing at the DMV
- (Check with your state DMV for
specifics.)
- To pass the written test at the
DMV
As you can see, adding the Doubles/Triples Endorsement is simple — but
maybe you want more guidance than just flipping through the DOT manual.
That’s where we come in.
We’ve taken all the DOT and FMCSA regulations and built a comprehensive
Doubles/Triples Endorsement Study Guide. It includes video training modules
that walk you through everything you need to pass the written test — plus two
downloadable practice tests with answer keys.
Our Study Guide is available here for just $14.99!
Like all our courses, the Doubles/Triples Endorsement Study Guide is
self-paced and designed by industry experts and professional educators — so
what you learn sticks with you long after you finish.
