When can we use high beams?

The correct answer is: When there are no streetlights on the road and no oncoming vehicles. In New Zealand, as in many other countries, high beams are primarily used to enhance driver visibility during nighttime or low-light conditions, especially on open roads without streetlights and where there are no oncoming vehicles. Using high beams helps drivers see further ahead, such as spotting animals or other obstacles that may cross the road. However, using high beams when there are oncoming vehicles or pedestrians can cause glare and potentially create safety hazards. Therefore, it is inappropriate to use high beams in these situations.
