Final answer:
At an intersection, you must obey all traffic signals and signs, and give right of way according to traffic rules. In extraordinary circumstances, such as a medical emergency, there may be a moral argument to break a traffic rule to ensure greater overall benefit.
Step-by-step explanation:
When you come to an intersection and try to make a move, the general rule to follow before you pull out is to obey all traffic signals and signs, and give right of way according to established traffic rules. This includes stopping at red lights, yielding to pedestrians, and allowing crossing traffic to proceed when they have the right of way. However, there can be exceptional circumstances where breaking a traffic rule could be considered, such as in an emergency situation. For instance, in the hypothetical scenario presented, if there is a pregnant woman about to give birth in the vehicle, and there are no other cars around at 4 AM, one might argue that proceeding through a red light could be justified to quickly get to the hospital. This is a rule utilitarian (RU) perspective, which suggests that the moral action is the one that results in the greatest utility or good. It's important to note that in real life, such actions can still be illegal and typically emergency services should be called in such situations.
