OVERTAKING IN THE DARK AND IN THE DAYLIGHT

DRIVERS' ABILITY TO MAKE SAFE OVERTAKINGS IN DAYLIGHT AND IN THE DARK WAS STUDIED IN A TEST. A CONSIDERABLE NUMBER OF DRIVERS MADE A JUDGMENT WHICH IN THEORY WOULD HAVE RESULTED IN A COLLISION WITH THE ONCOMING VEHICLE (60 PERCENT IN THE DARK, 74 PERCENT IN DAYLIGHT). REASONS FOR ERRONEOUS JUDGMENTS WERE FOUND TO BE MAINLY THE SPEEDS USED (ANALYSIS OF VARIANCE), AGE OF TEST PERSONS, DRIVING EXPERIENCE (IN DAYLIGHT) AND THE POWER OF THE ENGINE. WHEN THE SPEED OF THE ONCOMING VEHICLE WAS HIGHER THAN THAT OF THE VEHICLE AHEAD THE NUMBER OF ERRONEOUS JUDGMENTS WAS LARGEST. DRIVERS WITH POWERFUL VEHICLES MADE A SMALLER NUMBER OF ERRONEOUS JUDGMENTS THAN PERSONS WITH LESS POWERFUL VEHICLES. IN THE TEST IN THE DARK IT WAS FOUND THAT OLDER DRIVERS MADE A LARGER NUMBER OF ERRONEOUS JUDGMENTS THAN YOUNGER DRIVERS. IN DAYLIGHT THE RESULT WAS OPPOSITE.
