That's not one of the universal CDL endorsements, and is a state-specific add-on, or else it's a restriction which is also state specific. Please identify which state you hold a CDL in.
Some different endorsements available for a CDL driver include the ability to carry a passenger, double or triple trailers, hazardous materials and school busses. You can view them at http://www.fmcsa.dot.gov/registration-licensing/cdl/cdl.htm
My Class A with two endorsements was $35.
As for endorsements exclusive to a CDL, you can get hazmat, passenger, and tanker endorsements. You can also get a motorcycle endorsement, which can be placed on any class of licence. The only endorsement you wouldn't be able to get is the endorsement for double and triple trailers.
Yes, it does. If your Class B job requires additional endorsements (such as hazmat, tanker, etc.), you must still have those endorsements on your Class A CDL in order to perform that work.
X is a combination of Hazmat (H) and tanker (N) endorsements.
Only passenger and motorcycle endorsements require a road test of their own.
.04, federally, for any CDL, regardless of endorsements. States can have tighter restrictions, including zero tolerance.
It seems like you're referring to endorsements. "T" is the endorsement to pull double and triple trailers. "X" is a combination of two endorsements - Hazardous materials, and tanker.
The X endorsement is a combination of two endorsements - Hazmat (H) and tanker (K).
