What is a Queue?
A queue is the line of vehicles that is slowed or stopped due to a construction zone or road hazard.
In early 2020, INDOT launched the Protect the Queue Program. The purpose of this program is to Protect the Queue by making motorists approaching the work zones aware that they need to BE PREPARED TO STOP. Queues present an increased risk to motorists and workers because of the speed differential between approaching traffic and traffic that is traveling through or stopped within the work zone. Queues increase the risk of secondary crashes – crashes that occur within the queue (backup) that resulted from an original incident. These are often more hazardous than the original incident. INDOT is committed to reducing the risk of secondary crashes by Protecting the Queue through advanced queue awareness and alerting motorists to BE PREPARED TO STOP.
How INDOT Will Protect the Queue
On select contracts, INDOT will provide queue trucks about a 1/2 mile upstream of a queue to alert motorists to BE PREPARED TO STOP. Warning lights will emphasize the BE PREAPRED TO STOP message when queue trucks are actively providing advanced queue awareness. A second queue truck will be used to accommodate queue growth. This is discussed in detail in the Training Video and Special Provision provided below.
