The experiment investigating the effect of a warning pennant in bicycles showed that vehicle drivers give way more to bicycles fitted with pennants than to those without such a device. On highways with no oncoming traffic, the bicycle was generally passed from far enough however, so that a bicycle with a warning pennant was passed from a longer distance. Actual risks are created on highways when there is oncoming traffic. In these situations, the warning pennant improved the safety of bicylce riders. A bicycle without a warning pennant was often passed very closely while drivers moved to the lane of the oncoming vehicle when passing a bicycle with a warning pennant. Experiments at various speed limit zones showed that the higher the speed of the vehicle the longer the distance at which the bicycle is passed. The distance is longer for bicylcles with a pennant than for bicycles without such a device. The warning pennant was found to have no significant effect on driver behavior in towns - its effect on the safety of bicycle of bicycle traffic was largest in the dark in the case of heavy vehicles passing the bicycle. According to the results of the interview of vehicle drivers, bicycle riders generally abide well with traffic regulations. The worst faults are made at intersections. The safety of bicycle traffic could best be improved by education and training and by construction of separate bicycle routes. Vehicle drivers were almost unanimous about the safety-improving effect of bicycle warning pennants.
