Can you take Cdla test with dually and trailer?

Alright yall keep messing the gvwr and gcwr up. Gvwr is the gross vehicle weight rating. Or the total weight the vehicle can weigh, including tongue weight, payload, weight of passengers. Etc. Same on trailer. It's the weight the trailer can hold, plus the weight of the trailer. The gcwr is the total weight the truck can have completely. Includes payload, people, weight of truck AND weight of trailer and payload. Basically the total weight it can have if you plopped the entire thing on a scale with anything hooked up to it. This is why most trailer axle ratings are LESS than their gvwr because its assumed you load the trailer correctly and put ~20% on the tongue for a gooseneck.

in order to take your cdl with a truck UNDER 26000 gvwr it must have a gcwr over 26k and a trailer attached with it's own gvwr of more than 10000 lbs (most goosenecks). For example a properly equipped f350 dually has a gvwr of 14000 lbs but a gcwr of 40000 lbs.

Side note. The gcwr is more important than the tow rating for this reason. If the tow rating is 32000 lbs but you load the truck up with a bunch of people and stuff and fuel and it weighs 10000 lbs the actual tow capacity is limited by the gcwr, NOT the towing capacity

Hope that's clear as mud.

 

I really don’t understand what is so complicated about a Class A having a GCWR of over 26000 (26001 or more) with a trailer GVWR of over 10000 (10001 or more). With a “dually” and a trailer as the OP was inquiring about, the L restriction would apply with no air brakes, as well as the O restriction which I haven’t seen anyone mention.

 

But how do you get the truck and trailer to the facility to take the test?

Frustrated in TX

 

What’s the point of having a CDL-A if you have air brake restriction or a manual restriction?


Mind as well take the test on a old manual Day cab with a 20 foot flatbed trailer. Get it over with, its basically the same set up as a dually with a trailer just a bit taller.

 

Gross combined weight rating
GCWR
Over 26001 lbs That’s all that is required.

The key is combination vehicle.
You can get tested for a CDL with a dually and trailer.
It will be restricted. No air brakes. It may also get an automatic restriction it the truck has an automatic transmission.

Know several people in multiple states that have obtained a CDL this way. From what information they have supplied, the actual test was almost exactly the same, just no air system tests.

 

Also don't forget that one must use a 5th wheel trailer and not a gooseneck.
If a gooseneck is used there will be a restriction like the air brake, but for 5th wheel.

 

Hey! I am about to take this with my 3/4 ton and 4 horse LQ trailer. How different was the inspection from the CDL manual for semis?

 

I have an air brake truck pulling 40ft gooseneck that has electric brakes, will the air brake truck keep me from getting air brake restrictions?

 

It might get a 'no full airbrake' depending on your state. Look up license restrictions on your state's DMV website.
