A Danish nation-wide seat belt survey in 2003 shows an av-erage wearing rate of 84% for car drivers, 64% for adults in the rear, and 62% for drivers of vans below 3500 kilos. Compared to a similar survey in 2001, wearing rates are unchanged for drivers of cars and vans, whereas the wear-ing rate for adult back seat passengers above the age of 15 years has increased from 53% to 64%. On motorways and highways, wearing rates are about 89% among car drivers, 67% among van drivers, and about 67% among back seat adults. On urban roads about 80% of the car drivers, about 67% of back seat adults, and about 55% of the van drivers use their seat belt. Specifically on urban roads, the 2003 survey reveals a sig-nificant increase in wearing rates among adults in the rear. Similar, but minor increases, are seen among drivers of cars and van, but these changes are counterbalanced by a downward trend on motorways and highways resulting in an unchanged average. The results point at a continuous need to increase the use of seat belts among drivers of cars and vans, and adults in the rear.
