how long does endorsements last

They last as long as the license does unless the license says otherwise. Renew them with the license.

 

You will have to take the haz-mat test at every renewal if you get that endorsement.

 

This is true. For HAZMAT you must also do another background check. That means re-fingerprinted, and all the fees.

 

If you have a decent employer they will reimburse the fees as well as the cost of TWIC and a passport .
Employers are required to give additional hazmat training that has to be renewed every 3 years .

 

I dont completely understand the question so i'll give both answers:

There is no background check for tankers and doubles.

Tankers and doubles last as long as the license.

And i have my XT endorsements (tankers, haz, doubles) and i dont know if you already took the tests, but....the only one to worry about is hazmat. thats a little bit hard. but tankers, doubles are all obvious questions.

i had one question on my doubles test..."if you are hookin up a set of triples, should the drain valve on the back trailer be open or closed?"

...DRAIN VALVE. come on. all drains are always closed unless youre DRAINING the tanks....

 

All endorsements have to be taken (tested) each time you renew your license. Tanker, doubles, bus and the air test if your states have that as a separate class (like IL). But they do have to be taken again. You don't think the states will give up that $25 a test do you?Those endorsements aren't there forever like the M for motorcycle is which you don't have to re test for.

The Haz-Mat has to be re-verified with the back ground check and costs a bundle unless they dropped that stupid cost down some! Just be thankful they extended the CDL's for 5 - 7 years instead of the usual 3 years!

Unless this was a trick question then I'll put it this way. When your license expires everything on it expires with it! ROFL!

 

I live in TN and only had to re-take the Hazmat test
