Final answer:
In physics, the only situation where you can make a left turn against a red light is in a rotating frame of reference, such as when you are making a right turn in a car.
Step-by-step explanation:
In physics, the only situation where you can make a left turn against a red light is if you are in a rotating frame of reference, such as when you are driving a car and making a right turn.
When you make a right turn in a car, you feel a fictitious force pushing you to the left, but in the Earth's frame of reference, you are actually moving in a straight line.
This fictitious force is due to the car being used as a frame of reference.
