The following junction types typically permit U-turns but are not designed specifically for that purpose. Normal at-grade intersections on divided highways often allow traffic traveling on the divided highway to perform a U-turn, often when there is a green light for traffic turning onto the side road, crossing the opposing lanes (left turns in countries where traffic drives on the right ...
A diagram of a Texas U-turn, also known as a Texas turnaround (this one with the local road over the limited-access highway) A Texas U-turn, or Texas turnaround, boomerang, or loop around, [citation needed] is a lane allowing cars traveling on one side of a one-way frontage road to U-turn onto the opposite frontage road (typically crossing over or under a freeway or expressway).

Making a U-turn at a road segment signed No U-turn or painted double solid yellow or white lines or no-overtaking lines. Making a U-turn at a road segment prohibiting left turn. Not surrounding a roundabout to make a U-turn in such an intersection.
RIRO is an important tool of access management, itself an important component of transportation planning.A study applying access management guidelines to the redesign of Missouri Route 763 in Columbia, Missouri [4] illustrates how RIRO, combined with signalized intersections designed to permit U-turns, can accommodate high volumes of traffic with low delay and high safety.
A directional interchange is a grade separated junction between two roads where all turns that require crossing over or under the opposite road's lanes of travel to complete the turn utilize ramps that make a direct or semi-direct connection.
Severe turbulence forced a flight that took off from Stockholm and was destined for Miami to make a U-turn over Greenland Thursday, according to the airline. The Scandinavian Airlines flight...
A three-way intersection is a junction between three road segments (arms): a T junction when two arms form one road, or a Y junction, the latter also known as a fork if approached from the stem of the Y. Fork in the road Y-junction. A four-way intersection, or crossroads, usually involves a crossing over of two streets or roads.
In other contexts, the intersection is called a median U‑turn crossover or median U‑turn, or restricted crossing U-turn (RCUT). [ 1 ] [ 3 ] [ 4 ] The design is also sometimes referred to as a boulevard left , [ 5 ] a boulevard turnaround , [ 6 ] an indirect left turn , [ 2 ] [ 7 ] a Michigan loon , [ 8 ] a J‑turn , [ 9 ] P‑turn or a ...
