Description: A T junction (or T intersection) has 3 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.
