Critical Self Knowledge

Drug tests check for drugs.  Alcohol tests check for alcohol. But impairment may have many causes.  Most cannot  be determined with multiple tests. Marijuana, for instance, remains in your system for at least three weeks and for virtually all of that time has no impairing effect.  A test for its presence is not useful.  Impairment due to fatigue, illness, or concussion are not detectable with a drug test.  DRUID tests for impairment, regardless of cause.  It offers, in real time, performance scores relative to the ability to safely operate a vehicle.  It is calibrated against the Standard Field Sobriety Test.  It ensures individual, workplace and public safety.
