When following another vehicle at night, when must you use low beam headlights?

Using low beam headlights when following another vehicle at night is essential for safety and visibility. The correct response of within 60 metres is based on the need to avoid blinding the driver of the vehicle ahead. High beam headlights can create glare that impairs the vision of other drivers, particularly in conditions where visibility is already limited, such as at night.

By using low beam headlights at this distance, you ensure that you are providing adequate illumination for your own visibility while also respecting the safety of the driver in front of you. This practice reduces the risk of accidents and enhances overall road safety during nighttime driving conditions. Additionally, other distances mentioned, such as 100 metres or 30 metres, do not align with the recommended practices for safe driving in these scenarios. The option suggesting that the use of low beams depends on foggy conditions does not correctly address the specific rule regarding following distances at night, as low beams are always preferable to prevent glare, regardless of weather conditions.
