Abstract
Advisory speed limits are meant to be used discontinuities in situations are recognised by the road user; they at the same time do not give a clear suggestion as to the speed which should be sustained. At the moment advisory speed limits are almost only applied in narrow bends. This seems to be effective. Suggestions as to wider application of advisory speed limits should be treated with some reserve. Ineffective applications will lead to the devaluation of the measure and to more accidents at places where advisory speed limits have a real influence on the speed pattern.
