In this study, collision and braking behavior and braking distance of the enforcement device were investigated for characteristic evaluation. The basic theory for the braking distance was derived using the impulse momentum equation and the law of the conservation of energy. By this basic theory, effective arm angle range of enforcement device was clarified. And also, the collision test was carried out by simple model of the enforcement device and the vehicle. The behavior of the enforcement device was examined by the simple model with 3 kinds of different arm angles. The braking distance by the experiment was well agreement with theoretical result. It is possible to optimize and improve the enforcement device by these evaluations of collision behavior.
