When should high beams be turned off while driving?

High beams should be turned off when there is oncoming traffic or when you are following another vehicle closely. This is important for safety as high beams can blind or distract other drivers, especially at night. When another vehicle is approaching, their drivers rely on their own vision and having your high beams on can hinder their ability to see safely. Similarly, when you are closely following another vehicle, the glare from your high beams can affect the other driver's ability to see the road ahead, potentially leading to accidents. Therefore, it is a common practice and often a legal requirement to dim your high beams in these situations to promote safe driving for everyone on the road.
