We recently posted a picture of three cars stopped at a 3-way intersection and asked our followers which order they should proceed through the intersection. Below, we explain the answer to our question. Additionally, drivers, bicycle riders, electric scooter riders, and pedestrians must also follow right-of-way rules.
A three-way junction or three-way intersection is a type of road intersection with three arms. A Y junction or Y intersection generally has three arms of equal size. A T junction or T intersection also has three arms, but one of the arms is generally a minor road connecting to a larger road. Some T junctions are controlled by traffic lights , but others rely upon drivers to obey right-of-way rules, which vary from place to place. For example, in some jurisdictions, vehicles on the right always have the right-of-way even at T junctions ,  while in other jurisdictions, vehicles travelling on the "through" road of a T junction have the right-of-way, meaning that vehicles approaching the "major" road must allow through traffic to pass before joining the flow of traffic. 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 In Taiwan administered by the Republic of China , when at least two vehicles reach a T intersection without a working traffic light , the vehicle on the side road is to yield to any other vehicle straight on the main road. If two vehicles want to turn left, the vehicle on the left is to yield.
First off, I love your stuff. Very insightful. My question is this: what are the rules of a three-way? Thanks for writing in. To be honest with you, I've never had a three-way. The closest I've ever been to having one was in middle school. I used to break into my neighbors house at night to steal sugar based cereal, because my mom wouldn't let me have it. She said it would eat holes in my brain and that's exactly what I wanted- holes in my brain so I would have room for more information.
