T intersections are the most basic of intersections where one road meets another at right angles (or close to a right angle). They are less complex than crossroads. T intersections work well in low and medium volumes of traffic but can be difficult to emerge from when turning right if traffic is heavy. When a T-intersection gets busy, or there are a number of accidents, it might have traffic lights installed to control when vehicles can go. Otherwise the intersection might be uncontrolled (no lines), a give way (a white line) or a stop (yellow line).
When a stop sign is placed at a T-intersection it is usually because visibility of the road is restricted as you approach it.
