Reduced conflict intersections decrease fatalities and injuries caused by which type of crash?

1. T-bone

2. Head-on

3. Rear-end

4. Side-swipe

The correct answer is: T-bone

Reduced conflict intersections are designed to minimize the chances of direct collisions that often result in serious injuries or fatalities. These intersections typically aim to decrease the angle at which vehicles cross paths, which is particularly effective in reducing T-bone crashes. T-bone accidents occur when one vehicle strikes the side of another, often resulting in severe impacts because of the vulnerability of the passengers on the side of the vehicle being hit. By implementing designs such as roundabouts or one-lane entries that control turning movements, the frequency of T-bone collisions is significantly lowered as the points of potential conflict between vehicles are reduced. The other types of crashes—head-on, rear-end, and side-swipe—are less directly impacted by the intersection designs specifically aimed at reducing conflict points prevalent in T-bone collisions. For instance, head-on collisions often happen on straight stretches of roadway or when vehicles travel in opposite directions without proper barriers. Rear-end crashes usually arise from stopping or slowing traffic and are influenced by different factors such as tailgating or distracted driving. Side-swipe incidents predominantly occur when vehicles are traveling parallel to each other, often in blind spots, which is also not directly related to intersection design. In essence, the focus of reduced conflict intersections on minimizing direct
