What does 'yield speed but not lane' mean?

[DeGrant]

Yielding speed but not lane refers to maintaining your own lane and minimizing lane changes, even if the vehicle behind honks to urge you to yield the lane. In such cases, it's preferable to reduce speed and let the rear vehicle change lanes to overtake. Yielding speed means appropriately slowing down when a vehicle intends to merge into your lane, allowing the rear vehicle to overtake quickly. Yielding the lane, on the other hand, involves changing to another lane to make way for the merging vehicle during driving. Originally, the concept of 'yielding speed but not lane' was primarily about highway driving. However, in real-life situations, this principle isn't always 100% applicable on highways. In fact, when you can ensure your own vehicle's safety, it might be better to consider both yielding speed and the lane to avoid potential accidents.
