If the total weight rating of the combination is over 26,000 lbs., then yes, you will. If the trailer itself is rated at over 10,000 lbs., you will need a Class A CDL. If it is rated at under 10,000 lbs., then you would need a Class B CDL. Note that this only applies to combinations over 26,000 lbs. GVWR - you can pull a 15,000 lb. rated trailer behind a 10,000 lb. rated truck with a regular Class C licence, but, if you pulled that same trailer behind a 15,000 (or more) rated truck, you'd be operating a combination rated over CDL weight, and would require a Class A CDL.
someone needs to tell me yahh or nahhh
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.
On a CDL under endorsements, it's an endorsement for double and triple trailers
Yes
It's an endorsement to pull double or triple trailers.
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
They require a tanker endorsement, and most commodities they haul also require the driver to have a hazmat endorsement.
An "H" endorsement on a Commercial Drivers License "CDL" means that a driver is qualified to transport hazerdous materials.
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 you can. You can pull doubles and triples. You can pull two 48 trailers and two 53 foot trailers. You can pull three 48s, but you cannot pull three 53 foot trailers.
Yes
No
A bobtail can be driven with a Class B CDL, but if you're driving tractor-trailers for a living, you'd have a Class A CDL, anyhow.
