Final answer:
Low beams should be used both at night in the city and in foggy or misty weather to avoid blinding other drivers. It is improbable for the moon to blind a driver temporarily, so police may not believe such a claim. High beams are appropriate in very dark areas without other cars present.
Step-by-step explanation:
In which of the following situations should you use your low beams? The correct answer is both I. At night in the city, and II. In foggy or misty weather. You should use low beams in the city at night to prevent blinding other drivers with your headlights. Similarly, in foggy or misty conditions, it is advisable to use low beams because high beams will reflect off the fog or mist and can impair your visibility further rather than helping you see better.
Regarding the question about the car accident at midnight during a full moon, it is highly unlikely that the moon could be bright enough to blind someone momentarily, as the moon's light is not as intense as artificial sources such as headlights. Therefore, the police would likely be skeptical of the driver's claim of being blinded by the moon.
As for the use of high beams, high beams can be valuable in dark areas without streetlights, where visibility is significantly reduced. However, you should lower your high beams to low beams when another car is approaching to avoid blinding the other driver.
