When are you allowed to use your high beams?

Using high beams is appropriate on dark roads with no oncoming traffic because they provide better visibility beyond what standard low beams can offer. High beams illuminate a wider area and allow drivers to see further down the road, which is especially useful when there are no streetlights or other vehicles around. However, it is crucial to switch to low beams when there is oncoming traffic or when following another vehicle closely, as high beams can cause glare and impair other drivers' vision. This practice maximizes safety for all road users.
