The sign that indicates a road sharply intersecting another road at a 90-degree angle is known as a T intersection. A T intersection typically occurs where one road ends and meets another, creating a distinct “T” shape. This configuration is important for drivers to recognize since it often requires them to yield to the road that is continuing straight, thus enhancing safety at the junction. A Y intersection, while also a type of junction, does not represent a 90-degree angle as the roads are typically diverging rather than meeting at a sharp right turn. Low clearance signs relate to height restrictions for vehicles and are not relevant to intersections. Cross-road signs indicate the presence of another road crossing the roadway you are traveling on, but this can involve intersections at various angles, not specifically at a 90-degree angle like a T intersection does.
