Final answer:
An operator must signal for at least 100 feet before turning. In emergencies, such as when a pregnant woman is in labor, rule-utilitarian ethics can justify breaking certain traffic laws for greater utility.
Step-by-step explanation:
According to the Transportation Code, an operator intending to turn a vehicle right or left shall signal continuously for not less than the last 100 feet of movement of the vehicle before the turn. This rule ensures that other drivers and pedestrians are warned of your intention to turn, thus reducing the potential for accidents. However, in an emergency situation, such as when a pregnant woman is in the backseat about to deliver, and the vehicle is on the way to a hospital at 4 AM with no other traffic around, a rule-utilitarian (RU) might argue that the morally correct action is to prioritize the woman's immediate medical need and proceed through the red light to get to the hospital more quickly, providing that it is safe to do so.
