When to turn on high beam lights?

You should turn on your high beam lights when driving in dark, rural areas with little to no street lighting, as they provide better visibility. However, it's important to switch them off when approaching oncoming traffic or when you're within 500 feet of another vehicle to avoid blinding other drivers. Additionally, use low beams in fog, rain, or snow, as high beams can create glare in these conditions. Always be mindful of local laws regarding high beam usage.
