An interchange with a series of entrance and exit ramps resembling the leaves of a four-leaf clover.

A junction where traffic flow is controlled by signs or by default 'right-of-way' rules instead of signals.

A junction where drivers are rerouted to make a left turn or sometimes a U-turn from a right-hand lane.

A junction where roads form a 'Y' shape and merge or diverge at an acute angle.

A complex junction that separates traffic by levels with bridges and/or tunnels to allow traffic to pass without intersection.

A configuration where each direction of a main road is separated by a barrier and has its own set of signal phases.

A junction where two roads cross each other at a grade.

An innovative intersection design that allows left-turning traffic to cross opposite traffic before the main intersection.

A crossroad managed by traffic lights which regulate the flow of traffic.

An intersection that adds a new road within a quadrant to avoid turning traffic conflicts at the main intersection.

A junction typically associated with highways where local roads cross a highway with on and off ramps.

A junction that requires vehicles on the minor road to turn right and then perform a U-turn to go in the opposite direction.

A circular intersection with an island in the center, where traffic moves in one direction around the island.

A roundabout with spiral markings that guide drivers into lanes early and reduce conflicting traffic paths.

A junction where three roads come together and one road ends.

An alternative design where left-turning vehicles cross opposing traffic before the main intersection.

A type of intersection where side street traffic is required to turn right and then perform a U-turn for other movements.

A junction where through movements from side streets are prohibited, and drivers must use a median U-turn instead.

Resembles a cloverleaf interchange but with fewer loops, often utilizing ramps instead.

Features a bridge or tunnel allowing through traffic on the main road to bypass the intersection while turns are handled at grade.

An intersection that connects two roundabouts in close proximity, sometimes referred to as a 'dogbone' intersection.

A highway interchange where a single traffic signal controls all turning movements.

An interchange that spans over three vertically separated levels, allowing for free-flow movement in multiple directions.

A unique turn method where turning vehicles move to the far side of the intersection to make the turn.

A staggered intersection that splits roadway into discrete segments with controlled entry and exit points, to allow smooth traffic flow.

A highway interchange that temporarily shifts traffic to the opposite side of the road to facilitate left-turning movements.

Redirects turning traffic to a parallel roadway prior to rejoining the main road, improving flow and safety.

A T-intersection that allows a right-turn from a minor road without stopping, as the major road through lane doesn't have to stop.

A junction where the side roads do not align directly opposite each other, creating two separate T-intersections.
