This paper attempts to use CVM to measure the willingness to pay (WTP) for drunk driving and risk a ban. We assume ”adventure” might raise satisfaction. This is the reason why people drive while drunk, he/she must be willing to pay (the penalty) when arrested. The trade-off between satisfaction and penalty depends on the intensity of personal subjective perception of enforcement of drunk driving. The stronger the enforcement perception, the lower the possibility people are willing to pay the fine of this risky behavior. Rational people's behavior for drunk driving is affected by his/her enforcement perception and accident risk perception. We use these two perceptions to evaluate risk. The results of our observed research indicate that the WTP amount for the risk of a ban is from 15 to 16.6 thousand NT dollars.
