GLARE EFFECTS OF HIGH BEAM ON MOTORCYCLES IN DAYLIGHT

BLENDINGSEFFEKTER AV FIJERNLYS PA MOTORSYKLER I DAGSLYS

In collisions at intersections between cars and motorcycles the car drivers are usually at fault. A possible explanation for this is that the car drivers do not 'see' motorcycles, either because the shape and color of motorcycles makes them blend with the background and hard to see or the car drivers have a strong set to just notice other cars making them overlook motorcycles even though they are clearly visible. As a measure to improve the motorcycles' visibility it has been suggested that motorcycles may use the high beam during day time. An argument against this suggestion has been that the high beam may cause glare effects that may dangerously degrade the visual ability of other drivers. This study investigated the effects of a motorcycle headlight (light off, low beam on, high beam on) used in day light conditions on visual acuity and contrast sensitivity.
