Which type of intersection is associated with increased right-angle crashes?

Right-angle crashes, also known as T-bone collisions, occur when the front of one vehicle collides with the side of another. These types of crashes are particularly prevalent in intersections where drivers may not have a clear indication of right-of-way, leading to unilateral movement without adequate checks for oncoming traffic.

At stop-controlled intersections, one vehicle is required to stop while the other may proceed if it is clear. This stop-and-go nature can lead to drivers misjudging their gaps, particularly when they assume that traffic is entirely cleared without considering other vehicles that may not be stopping. When the stopped vehicle proceeds while another vehicle is approaching, a right-angle collision can easily occur as the vehicles intersect at an angle.

In contrast, uncontrolled intersections may still have a risk factor but often involve drivers who must make their own judgments about who has the right-of-way. Roundabouts are designed to improve traffic flow and reduce the likelihood of right-angle collisions by requiring all vehicles to merge and navigate in a way that keeps the flow continuous and minimizes high-speed impacts. Traffic signalized intersections can also reduce the likelihood of right-angle crashes by clearly directing traffic signals that create patternized movement, though they might still result in other types of collisions.

Therefore, the association of
