Is there a time limit on reasonable suspicion drug testing?
There is a common misconception that post-accident and reasonable suspicion testing have the same timeframes and time limits; however, they do not. Whereas all post-accident drug testing is to be conducted within 32 hours of the accident, there is no similar time frame or time limit on when to conduct a reasonable suspicion drug test. When a trained supervisor makes a determination that a reasonable suspicion exists, the drug test must be performed as soon as possible; but there is no time limit on when to cease attempts to test. It is always a good idea to document reasons for extended delays in testing.
