Philadelphia Drivers License Practice Test

Using high beams is appropriate on open roads with no traffic because these situations can often be dark and lacking sufficient illumination. When driving in such areas, high beams provide better visibility, enhancing your ability to see further down the road and spot potential hazards that might not be visible with low beams. In contrast, in well-lit city areas, high beams can cause glare for other drivers and are unnecessary since streetlights provide ample lighting. Following another vehicle with high beams can also create discomfort and distraction for the driver in front. Additionally, using high beams in poor weather conditions, such as rain or fog, can reflect light off the precipitation, causing visibility to decrease rather than increase. Thus, using high beams in these conditions is not advisable.
