So I currently have my cdl since 2018 and have experience. I'm currently working in the warehouse at my job and they are looking for dedicated sleeper team drivers at another warehouse for the company i'm working for. I'm interested in taking the position, but I need to get my double/triple endorsement. I know the test is 20 questions. My main question is for the testing is it all strictly the doubles section for the cdl manual, or 50/50 of the doubles and general knowledge section?
