Thank you for using JustAnswer. I am researching your issue and will respond shortly.
Was this a drug test administered through your employer, or probationary officer, etc...?
DOT drug and alcohol testing regulations for CDL drivers require certain types of tests, all of which are conducted while a driver is on duty not driving. A driver who fails a DOT drug or alcohol test is medically unqualified to drive any CMV, but a failed test does not actually affect their CDL.
Now if you were arrested and then given a drug test (administered by the state) then this could go against you and could cause you to have your CDL suspended.
So only if you are actually driving under the influence of the drugs could they suspend your license for the drug use...
Thank you for your answer
