These two factors are directly related to accident rates and cause many traffic accidents, especially among the younger population. Both alcohol and speed reduce our field of vision, which is known as the tunnel effect (only the centre of the road is perceived clearly, losing peripheral vision). (Photo 1) Traffic signs are also perceived less clearly, distances are misjudged, and our capacity for anticipation and reaction decreases (increasing the reaction distance).
