Driving while intoxicated is a serious problem in the US. What policymakers disagree about is how best to discourage drunk driving. This column argues that the perceived risk for detection has a deterrent effect on drunk driving. Harsher sanctions do not convey the desired effect if the perceived risk for detection is low. The best policy thus should increase the probability of detection or manipulate peoples’ beliefs for such a risk.
