What is the term for the back up of traffic caused by an incident or blocked lanes?

Explanation:
When vehicles are held up by an incident or blocked lane, they line up upstream of the blockage. That line of waiting vehicles is called a queue. The queue grows as more cars arrive than can pass through the bottleneck, and it shrinks again once the incident is cleared and flow returns to normal. Other options describe the situation in vague terms or aren’t the standard traffic engineering term for a line of waiting vehicles, so they don’t fit as precisely as “queue.”
