I know I need it. I have a dually with a GVWR of 14,000 and a fifth wheel with a GVWR of 16750. That will put me at 30750 well over the 26000 limit of a class C license. So I know I need a class A, I am just confused about the appropriate written tests to take before I am eligible for the driving test. The DPS office said I only needed the special requirements test and not the combination vehicle test. After looking at other posts on here I am pretty sure I do as other have said they had to. I have also seen some post saying I am required to take the air brake test from section 5. I was able to schedule another written test for tomorrow and will knock out the combination vehicle test hopefully and then hopefully make it through the driving test. Thanks to this site I have read through a bunch of post and saw I have to take the IMPACT training as well. Just hope they're a no more surprises for tomorrow. I am also a little confused on what will be required of me for the pre trip inspection. A lot of people here are saying the examiner looks over your truck and trailer rather than what I was expecting where I would have to explain everything to them.I guess I will find out tomorrow.
