What type of crash is most frequent on interstates?

The most frequent type of crash on interstates is rear-end collisions. These incidents typically occur due to the high speeds at which vehicles travel, as well as the limited reaction time drivers have when the vehicle in front of them suddenly slows down or comes to a stop. The nature of interstate driving, with vehicles often maintaining consistent and fast speeds, increases the likelihood of rear-end collisions when one vehicle fails to maintain a safe following distance.

Additionally, traffic congestion can exacerbate this issue, as vehicles may be moving at different speeds, leading to scenarios where a driver misjudges their stopping distance or fails to react promptly to the actions of the vehicle ahead. This type of collision may not always result in severe injuries compared to head-on or rollover accidents, but they are frequent due to the conditions prevalent on interstates.

Other types of crashes, such as head-on collisions and rollovers, tend to happen less often on interstates due to the design of these roads, which typically separate traffic traveling in opposite directions and provide multiple lanes for vehicles.
