Additionally, the specific driving impairments associated with BALS of 0.08% or higher were analyzed. Finally, the abilities of different coordination and reaction time tests were evaluated to determine if such tests were able to differentiate between BALS >= 0.08% and BALs <0.04%. All tests were evaluated objectively and subjectively. To summarize results, subjects were accurate at recognizing legal intoxication, but a third of the legally intoxicated subjects were still willing to drive. When BAL was >= 0.08%, individuals objectively performed more poorly on various parameters of the driving simulation, coordination, and reaction time tests. At these same BALs, subjects rated all of these tests to be more difficult, and their performance to be less accurate and more impaired. Experience on the simulator did not influence subjects/ willingness to drive.]]> Sat, 28 Aug 1993 00:00:00 GMT https://trid.trb.org/View/367547
