Samenvatting
A research has been done to the use and non-use of seat belts. After the law of January 1, 1971, by which seat-belts have to be in new cars, there was an increase from 22 to 37 %, but only 14 % of them was using those seat belts. When every driver and passenger should use their belts there can be a decrease of 350 fatalities per year.
