Road side interviews have been conducted in order to evaluate the use of a sign “Seat belt control” at control posts by the Public Roads Administration. Without the sign, the control posts are still visible, but drivers cannot know what type of control is conducted. It is found that, although the sign does increase the visibility of the control posts, it does not lead to a higher subjective risk of detection for not using seat belts, and it is unlikely that seat belt use will increase. The deterrence effect of the control posts may be reduced because drivers may feel less apprehensive about being fined for other types of traffic law violations.
