2 oz of urine is more than enough for a DOT test. DOT requires 45 ml of urine sample. The sample is then split 30/15.
Burnt Toast Reviewed by Burnt Toast on . D.O.T. Test I am a truck driver, and I have to take a DOT physical in a few days. I can pass the physical alright, but its the piss test that is going to hold me up. I know they do a split test. Im going to use sombody elses urine in a 2 oz bottle, then stick it up my boodie to keep it warm. My question is; Will 2oz be enough for a split sample. I thought about using a condom, but im not sure if they will check me for a hernia before they piss test me. Rating: 5
