Is it illegal to drive with high beams on the highway?

[KeeganLynn]

Driving with high beams on the highway is not illegal. Relevant details are as follows: 1. Avoid using high beams in urban areas: Generally, it's best not to use high beams when driving in the city because urban areas usually have good lighting conditions. The high angle of high beams can easily dazzle oncoming drivers and pedestrians, affecting their vision and posing safety risks. It is also considered impolite driving behavior. 2. Other areas: On highways or in rural areas without streetlights, using high beams can help expand the field of vision. However, when encountering oncoming vehicles, it is advisable to switch to low beams for safety and courtesy. When driving at low speeds, the engine's power generation is insufficient, and the battery is in a state of negative charge. Using high beams in such conditions can affect the battery's lifespan. Additionally, using high beams during low-speed nighttime driving increases fuel consumption, which is obviously uneconomical given the high fuel prices.
