Currently, specially trained drug recognition officers conduct field sobriety tests based largely on visual assessments, rather than testing of bodily fluids. “Right now, there are laws in place to deal with impairment, whether it’s drug impairment or alcohol impairment,” Farnworth said Thursday. There are three roadside tests, which are the same for identifying both alcohol and drug impairment, he said Friday. Maxwell said he believes drug recognition officers will be more effective than any technology in detecting impairment. Even if a saliva test is introduced, Maxwell said he believes drug recognition officers will continue to play a strong role.
