What causes crashes at intersections?

Crashes at intersections are often caused by inappropriate lane changes and running red lights because these actions directly compromise the flow and safety of traffic. Intersections are critical points where different road users converge, and the potential for conflict increases significantly due to the presence of vehicles traveling in multiple directions. When drivers change lanes without proper signaling or awareness, they can collide with other vehicles traveling in adjacent lanes. Similarly, executing a left turn or entering an intersection while disregarding a red light can lead to severe crashes, as other vehicles may have the right of way and expect to proceed unimpeded.

While adverse weather conditions, driving under the influence, and distracted driving certainly contribute to road safety issues and can cause accidents, they are not exclusively tied to intersections in the same way that running red lights and improper lane changes are. Intersections require heightened awareness of traffic signals, signs, and the actions of other drivers, making those specific behaviors particularly dangerous in these areas.
