You must use your headlights…?
- Between dusk and dawn and any other time you cannot see clearly for a distance of 150m
- Between 8PM and 6AM
- From 30 minutes after sunset until 30 minutes before sunrise or if visibility is reduced to less than 150 metres ✓
- Between sunset and sunrise
Answer: C. From 30 minutes after sunset until 30 minutes before sunrise or if visibility is reduced to less than 150 metres
You must use your headlights from 30 minutes after sunset until 30 minutes before sunrise, or when visibility is reduced to less than 150 metres.
Why this is the answer
The handbook states the lighting requirement begins 30 minutes after sunset and continues until 30 minutes before sunrise. That timing matches the correct choice. The choice also mentions visibility reduced to less than 150 metres; the supplied passage does not discuss that figure, so the sunset-and-sunrise timing is what the handbook directly confirms.
Why the other answers are wrong
- A. Between dusk and dawn and any other time you cannot see clearly for a distance of 150m — Dusk-to-dawn timing with a 150 m visibility limit is not the rule stated in the passage, which uses the 30-minute after-sunset and before-sunrise window.
- B. Between 8PM and 6AM — A fixed 8 PM to 6 AM schedule is not in the passage; the required period is tied to sunset and sunrise, not those clock times.
- D. Between sunset and sunrise — Sunset-to-sunrise is broader than the handbook rule, which starts 30 minutes after sunset and ends 30 minutes before sunrise.
Remember it
Remember it as half an hour after sunset to half an hour before sunrise, not the whole dark period.
