What is the rule about using high beam headlights?

Using high beam headlights is appropriate in dark conditions when there is no oncoming traffic because they illuminate the road far ahead and provide better visibility to the driver. This can enhance safety by allowing the driver to see potential hazards, pedestrians, or animals that may be on or near the roadway.

High beams are designed to project light further than low beams, which can be particularly beneficial in rural areas or on isolated roads where street lighting is minimal. However, it is essential to turn off high beams when approaching other vehicles or when driving in well-lit areas, as they can cause glare that impacts other drivers’ visibility.

In contrast, using high beams at all times is not advisable because they can blind oncoming drivers and lead to dangerous situations. Similarly, using them in adverse weather conditions like rain or fog is typically discouraged, as the light can reflect off precipitation, reducing visibility. Using high beams during the day is also not encouraged, as most daytime driving conditions do not require such powerful illumination and can create unnecessary glare for other road users.
