Under what conditions should you use your high beams?

Using high beams is appropriate on dark, unlit roads when there is no oncoming traffic because they provide increased visibility, allowing for better perception of potential hazards and obstacles that may not be easily seen with standard low beams. These high beams illuminate the road much further ahead, which can be crucial in rural or poorly lit areas where streetlights are absent.

In contrast, using high beams in busier city environments can cause glare and distract other drivers due to the reflective surfaces of buildings and vehicles. Heavy rain can also lead to reduced visibility, and using high beams may reflect off the rain droplets, making it harder to see. During the day, standard low beams are usually sufficient, as high beams can be too bright and unnecessary in well-lit conditions.
