Final answer:
High-beam lighting can be useful in most situations, but not when there is oncoming traffic or when following another vehicle closely.
Step-by-step explanation:
High-beam lighting can be useful in all situations, except when there is oncoming traffic. High beams produce a stronger and brighter light that can illuminate a longer distance, allowing drivers to see further ahead. However, using high beams in the presence of oncoming traffic can cause glare and make it difficult for other drivers to see, potentially leading to accidents.
When using high beams, it is important to switch to low beams when approaching other vehicles or driving behind someone, as this prevents blinding other drivers and ensures everyone's safety on the road.
In summary, high-beam lighting is helpful in most situations, such as driving on dark rural roads with no other traffic, but it should be avoided when there is oncoming traffic or when following another vehicle closely.
