Continuous-flow intersection

, Utah showing the layout and normal traffic flow in the southwest portion of the intersection. A continuous flow intersection (or CFI), also called a crossover displaced left-turn (XDL or DLT), is an alternative design for an at-grade road junction. Vehicles attempting to turn across the opposing direction of traffic (left in countries with right-hand traffic; right in those with left-hand traffic) cross before they enter the intersection. No left turn signal in the intersection is then necessary. Instead, vehicles traveling in both directions can proceed, including through vehicles and those turning right or left, when a generic traffic signal or stop sign permits. Its design also is promoted as part of the Federal Highway Administration's Every Day Counts initiative which started in 2011.
