the 2 most popular items for truck drivers are 1-the urine luck additive. this is 2 vials that you put directly into urine sample. this product only works if it has 90 minutes in your sample, but since they have to send your sample off to the lab, it will have plenty of time in there. This only works though if you are a heavy user (4 or more times a week). 2-quick fix (synthetic urine). This you will need to have some time to heat it up though, and you need to make sure that is within the temperature range.

with either of these products, you should be golden! go to urineluck.com, they are both made by spectrum labs.

Good Luck!
