Samenvatting
It is reasonable to predict that belt use can reduce the probability of injury by 20%; serious injury by 50%; and dead by as much as 75%. Because belt systems are already available in almost all cars, there would be very little added cost associated with such dramatic benefits. The major obstacle is motorists' unwillingness to use safety belts. As has been demonstrated in several countries, one way to overcome this resistance is to pass laws requiring motorists to use safety belts. Although even this has not been completely effective, it has substantially increased the number of motorists who are protected by belts.
