When driving at night with your high beams on, how close are you allowed to get to another car before you dim your headlights?
- 200 metres
- 150 metres ✓
- 100 metres
- 250 metres
Answer: B. 150 metres
At night, dim your high beams once you are within 150 metres of another vehicle.
Why this is the answer
The handbook requires low beams once you are 150 metres or closer to another vehicle, whether you are meeting it or following it. That distance is the cutoff, so you should switch by the time you are 150 metres away. The same section also suggests dimming early if you have trouble judging distance. The other distances do not match the high-beam dimming rule.
Why the other answers are wrong
- A. 200 metres — The handbook does not give 200 metres as the dimming point; it states that you must dim within 150 metres of another vehicle.
- C. 100 metres — The 100-metre figure describes how far high beams light the road, not the distance at which you must dim them.
- D. 250 metres — The handbook does not set the dimming point at 250 metres; it says to dim within 150 metres of another vehicle.
Remember it
When another vehicle is ahead or approaching at night, think "150 and dim" — meeting or following, low beams go on.
