Most of T-intersections have a T-INTERSECTION warning sign installed on approaches to the intersection to warn drivers that the road they are traveling on does not continue straight through the intersection. It is one of the intersection road signs that tell you what type of the intersection you are approaching so you can exercise extra caution and prepare to slow down, if necessary.
At an uncontrolled T intersection, the driver on the street which ends must yield the right-of-way to vehicles and pedestrians on the cross street.
Some T-intersections have additional YIELD or STOP signs installed to remind drivers that they have to give way to cross traffic. These are “sign controlled intersections” because the flow of traffic is regulated by road signs.
