The act of moving from a lane that ends to enter into another lane that continues forward is known as merging. This is an extremely critical maneuver and any error at this stage can lead to a merging accident. Most merging accidents in New York are known to occur when drivers change lanes without indicating their intention through a turn signal. Occasionally, a car driver will cross over multiple lanes or merge in such a way that they cut off someone on the lane into which they merge.
