Failed Drug Test, Never Done Drugs.

Don't want truckers to start this as an excuse, but I have read that having a UTI can result in great number of false-positives.

But here is the thing. When you go and take a drug test, they use a "dipstick method", which can be flawed - but in your favor. Which is why (if you test positive) they have you give another sample that they use a much more expensive and accurate test on. If you show positive on that 2nd test - you have drugs in your system.

The fact of the matter is, when discussing the accuracy of the drug testing and the fail rates, the numbers are wildly in the favor of the drivers, since the rate of failure is mostly on the "false-negative" side.

A Positive drug screen is accurate over 94-98% of the time. (and the subject is cleared by the 2nd test). A Negative drug screen shows an accuracy of only 83%.

So basically, if you're not using, you're literally fine. If you are using, you still have a .170 chance of getting away with it. (Which is the current batting avg of MLB All Star Chris Davis)

Yes I am married to one, at this moment she was not a user When we married. And her using is actually what's causing the divorce. As far as friends go oh, the only time I've ever had friends in my life was when I was driving truck, and when I was in the army. According to people I know I'm too anal retentive about the rules to be any fun at all. And I plan on putting distance between me and anyone that uses including my wife. Just got to figure out what I'm going to do with my son.

Roy B, your associations with users seem to be very close and tight. You're even married to one. Personally, I would take a different lesson away from all this than the one you took, but that's just me, and my handle describes me pretty well. I'm glad you're not using, but you sure could put a little more distance between yourself and those that do. You say you've started divorce proceedings - perhaps move somewhere else and start all over with a new set of friends would be wise also.

We all hope the best for you, but we also know a failed drug test is just about impossible to overcome in this career.

So my take away from this is:

Roy B did have drugs in his system, which is why he tested positive.

Only about 2-4% of the time does a false positive happen. So in theory, 2 to 4 people out of 100 could have a false positive.

However, if you do have false positive, they do a second test to confirm.

If don't have drugs in your system, but you test positive twice in row (only 2-4% chance), you are extremely unlucky.


Transportation Worker Identification Credential

Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.

Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.
