New Hampshire Drivers Practice Test

Using high beams in the presence of oncoming traffic or when following another vehicle closely is not advisable because high beams can cause glare that significantly impairs the vision of other drivers. High beams are designed to illuminate the road further ahead and are most effective in low-traffic situations where there are no other light sources. When oncoming vehicles approach, their drivers would be blinded by the bright lights, which can lead to dangerous driving situations and increased risk of accidents. Similarly, if you are closely following another vehicle, using high beams can reflect off the back of that vehicle, again causing glare that may be distracting or impairing. Additionally, using high beams in fog, populated areas, or well-lit streets is generally discouraged because the light can scatter off the fog or be unnecessary when streetlights are sufficient. Thus, recognizing the right conditions to use low versus high beams is crucial for safe driving.
