Final answer:
In Ohio, the law dictates you cannot make a right turn on red if no turn on red is posted. In emergencies, while people may feel the need to break traffic laws, it is not legally permissible to do so without risking violation of the law.
Step-by-step explanation:
In Ohio, you may always make a right turn on red except when a sign is posted indicating that no turn on red is allowed. In the specific situation provided, we're considering an emergency where a pregnant woman in the vehicle is about to deliver a baby. While generally, traffic laws must be adhered to for safety, the described scenario would likely be considered an exception by many, as the urgency to get the woman to the hospital could be considered paramount. However, this doesn't change the law regarding red lights. If you are driving and find yourself in a real emergency, the safest course of action is to call emergency services. Otherwise, even in urgent situations, it is not legally acceptable to make decisions that contradict traffic laws, such as turning right on a red when not permitted or proceeding through a red light without proper clearance.
