When driving with high beam headlights and a car is approaching, when must you dim them?

• A. At 100 metres
• B. At 150 metres
• C. At 200 metres
• D. At 250 metres

Answer: (B)

When driving with high beam headlights, it is essential to dim them when a car is approaching from the opposite direction to avoid blinding the other driver. The standard rule is to dim your high beams when an oncoming vehicle is within 150 metres. This distance is significant enough to ensure that the approaching driver is not affected by the bright lights, which can temporarily impair their vision. Adjusting your headlights at this distance promotes safety for both drivers and helps prevent accidents due to reduced visibility caused by glare.
