The report describes an inter-Nordic investigation of accident rate on paved roads with different pavement surface conditions. The investigation was based on data from measurements in 1982-86 of rut depth and unevenness supplemented with traffic and road data, weather statistics and information on traffic accidents with injuries. Accident in junctions were excluded from the analysis. The results indicate a lower accident rate for roads with more worn pavement surfaces - more uneven and with deeper ruts - than for those with only little wear. However, during days with more precipitation than 10 millimeters, the roads with worn pavements showed a higher accident rate. Rut depth and unevenness were originally measured for other purposes. The limited amount of data made it difficult to eliminate probable co-variation between pavement surface condition and road parameters like road geometry, speed limit etc.
