Final answer:
True, headlights must be lighted from sunset to sunrise to ensure visibility and safety since twilight illumination is not sufficient. The claim of being blinded by the full moon causing a car accident is questionable and police might be skeptical about its validity.
Step-by-step explanation:
Headlights must be lighted from sunset to sunrise—this statement is generally true. Driving laws usually require that vehicle headlights be turned on during this period to ensure visibility. As light scatters in the atmosphere, twilight provides some illumination even after the sun is below the horizon, but this is not sufficient for safe driving. Headlights contribute to safety by increasing a driver's visibility and alerting others of their presence.
In the event of the car accident occurring around midnight with a full moon, the claim of being blinded by the moon is questionable. While the full moon is bright and could potentially be distracting, it typically would not produce the intensity needed to blind someone as headlights or the sun would. Therefore, police might be skeptical about the driver's claim unless additional evidence supports this assertion.
