During what conditions is it advisable to use lower beams instead of high beams?

• A. In foggy weather
• B. At night on an open road
• C. When driving in the city
• D. When following other vehicles

Answer: (A)

Using lower beams in foggy weather is advisable because high beams can create significant glare when they reflect off the moisture in the fog, rain, or snow. This reduced visibility can make it challenging to see the road ahead and impair your ability to drive safely. Additionally, low beams provide enough illumination for seeing the road directly in front of you without causing the light to scatter, which can be particularly disorienting for both the driver and others on the road. While it might be acceptable to use high beams on an open road at night for enhanced visibility when there are no oncoming vehicles, the best practice in foggy conditions is to switch to low beams to improve clarity and safety. In the city or when following other vehicles, low beams are typically preferred as they minimize glare for other drivers and help to maintain safe driving conditions.
