Editing Three-way junction (section)

==Right-of-way==
Some three-way junctions are controlled by [[traffic light]]s, while others rely upon drivers to obey [[traffic#Passage Priority (right of way)|right-of-way]] rules, which vary from place to place:<br>
*In some jurisdictions, chiefly in European countries except the U.K. and Ireland, a driver is always obliged to yield right-of-way for every vehicle oncoming from the right at a junction without traffic signals and priority signs (including T junctions).<ref>{{cite web|url=http://www.sgi.sk.ca/individuals/licensing/studyguides/drivershandbook/roadrules/rightway.html|title=SGI - Driver's Handbook - Right of way|last=SGI}}</ref>
*In other jurisdictions (mainly in the U.K., USA,<ref>{{cite web | url=https://www.safemotorist.com/articles/right-of-way/ | title=Right of Way }}</ref> Australia and [[Taiwan]]<ref>Clause 2 of Section 1 of Article 102 of the Road Traffic Security Rules ([[s:zh:道路交通安全規則]])</ref>), a driver turning in a three-way junction must yield for every vehicle approaching the junction (on the way straight ahead) and, if the driver turns right in left-hand traffic/left in right-hand traffic, for every vehicle turning without crossing the oncoming traffic's side of the road (left in left-hand traffic/right in right-hand traffic) ''or'' (if two vehicles both turn right in left-hand traffic) for the right-turning vehicle approaching from the left/(if two vehicles both turn left in right-hand traffic) the left-turning vehicle approaching from the right (and a road going straight ahead at a three-way junction is normally marked as a priority road).

In the United States and some other countries, it is common to have stop signs facing each direction, although according to game-theoretical analysis, drivers have strong incentives to run the stop sign, while randomly removing one stop sign may lead to significant efficiency gains.<ref>{{Cite journal |last=Li |first=Jiasun |journal=George Mason University School of Business |date=2022-09-14 |title=Four-Way Stops |url=https://papers.ssrn.com/abstract=4197885 |language=en |location=Rochester, NY}}</ref>

In the People's Republic of China, going straight on red when approaching a T junction on the main road with the intersecting road on the left was permitted until the [[Road Traffic Safety Law of the People's Republic of China]] took effect on 1 May 2004.
