Dimming your high beams is important for maintaining safety on the road, particularly when you encounter oncoming traffic or are closely following another vehicle. High beams can create significant glare for other drivers, which can impair their vision and increase the risk of accidents. By dimming your high beams in these situations, you are showing consideration for other road users and ensuring a safer driving environment for everyone.

Driving in fog, while it may seem logical to turn on high beams for visibility, is actually counterproductive as the light can reflect off the fog and reduce visibility. In the absence of traffic, high beams can be used without concern for others. Using high beams during daylight hours is generally unnecessary and doesn't provide any benefits, as most drivers can see well enough without them. Thus, the correct practice is to dim high beams in the presence of oncoming traffic or when closely following another vehicle to prevent glare and enhance overall road safety.
