ALTHOUGH BEVERAGE ALCOHOL APPEARS TO GIVE SUBJECTIVE STIMULANT ACTION TO A PERSON, ITS REAL EFFECT IS A DEPRESSANT ACTION ON MOST OF THE FUNCTIONS OF BODY AND MIND. THE ALCOHOL EFFECT WHICH INTERFERES WITH DRIVING ABILITY IS FOURFOLD: (1) A POORER GRADE OF ATTENTION TO EXTERNAL SIGNALS AND ENVIRONMENT; (2) SLOWER RESPONSES OF EYES, HANDS AND FEET; (3) LESS DEPENDABLE, THAT IS MORE VARIABLE, MUSCULAR RESPONSES; (4) INCREASED SELF ASSURANCE WHICH PROMPTS TO THE ASSUMPTION OF RIGHT-OF-WAY AND WILLINGNESS TO TAKE A CHANCE. ALTHOUGH ALCOHOL IS DIRECTLY MENTIONED IN ONLY 7 TO 10 PER CENT OF FATAL HIGHWAY TRAFFIC ACCIDENTS, IT IS THE BELIEF OF INFORMED TRAFFIC OFFICIALS THAT ONE-THIRD OF SUCH ACCIDENTS ARE AT LEAST PARTLY CHARGEABLE TO USE OF ALCOHOL BY THE DRIVER. OFFICIALS NEED A METHOD TO DEFINITELY DETERMINE WHETHER A DRIVER IS INTOXICATED AS A BASIS FOR COURT ACTION. DETERMINATION OF PERCENTAGE OF ALCOHOL IN THE BLOOD OR URINE BY BIOCHEMICAL MEANS IS A FEASIBLE UNDERTAKING. /AUTHOR/
