 It is also straightforward to see how a legal rule might provide information that alters the agent’s beliefs about the likely outcome of various courses of action. Consider, for example, a driver on a mountain road who encounters a sign that indicates an impending curve on which the speed limit has been lowered to 15 miles per hour. In light of this sign, the agent should adjust her beliefs about the highest safe speed at which she can negotiate the road. Regulations of health and safety may operate in a similar way.
