Should you increase your high beam lights when you spot another vehicle?

Using low-beam lights when you spot another vehicle is essential for safety as it prevents dazzling the driver of the oncoming vehicle. High beams provide greater visibility but can impair the vision of other drivers, particularly when they are close or directly approaching. The primary purpose of this rule is to ensure that you maintain a clear line of sight while allowing others to see safely as well.

When driving, especially at night or in low-visibility conditions, it’s vital to prioritize the safety of all road users. Low beams are designed for situations where there is oncoming traffic or when you are following another vehicle closely, as they illuminate the road without blinding other drivers. This practice helps reduce the risk of accidents caused by temporary blindness due to bright lights, promoting a safer driving environment overall.

Increasing high beams would not only be counterproductive but could also be considered illegal in many jurisdictions as it endangers others on the road. The other options may imply scenarios where high beams might be safe, but they overlook the fundamental principles of nighttime driving etiquette and safety.
