A quick testing overview
Different situations. Different testing requirements.
FMCSA rules cover pre-employment drug testing, random testing, qualifying post-accident testing, reasonable-suspicion testing, return-to-duty testing, and follow-up testing. The applicable conditions and procedures depend on the testing reason.
A random testing program is not a fixed “every six months” test schedule for every driver. Random selections are unannounced and follow the applicable program requirements.
General reference: FMCSA testing types and requirements. A program purchase does not by itself satisfy every employer responsibility.
