echelon plowing
n.— «The decision reverses a previous policy of DOT Region 7 that was initiated along with a new plowing technique this winter. That technique, called echelon plowing, stalls traffic behind sets of plows moving in tandem to clear all lanes of a roadway at once. It has been used on Interstate 81, where drivers have complained of long waits behind the slow-moving vehicles.» —“Plows will yield to emergency vehicles” by Joanna Richards Watertown Daily Times (New York) Feb. 6, 2009.
