When following another vehicle at night, you should switch to low beam headlights before you get within what distance of it?
Answer: C — 60 metres
When following another vehicle at night, it's important to switch to low beam headlights before you get within a distance of 60 metres. This is because low beams provide better visibility and reduce the risk of blinding the driver ahead of you. Option A (30 meters) and Option B (45 meters) are not far enough to provide the necessary visibility and distance from the other vehicle. Option D (75 meters) is too far and may reduce your own visibility and reaction time.
