In comes solutions such as DRUID. Druid tests impairment by measuring ones response time, balance, and hundreds of neurophysiological indicators which helps to determine how impaired a person is objectively. The entire test only takes about 3-minutes to complete and plays like a video game. You have to complete 4-simple actions which then tallies up a score and tells you how impaired you are.  That’s it! The question is, “Does it work?”
