What is the most frequent type of crashes on interstates?

Rear-end collisions are the most frequent type of crashes on interstates primarily due to the high speeds at which vehicles travel and the close proximity in which they follow one another. On highways, traffic can change rapidly, and drivers may not have sufficient time to react to sudden slowdowns or stops of vehicles in front of them. Additionally, distractions like mobile devices or adjusting seating and climate controls can further reduce a driver's awareness of their speed and the distance to the vehicle ahead, increasing the risk of a rear-end collision.

This type of accident can occur in heavy traffic conditions where drivers might not maintain adequate following distance, as well as in lower traffic when drivers may not be vigilant about their surroundings. Implementing measures such as maintaining a safe following distance and being aware of the vehicles around you can help mitigate these types of crashes.

In contrast, while side collisions and head-on collisions can also occur on interstates, they tend to happen less frequently due to the nature of highway driving, where vehicles generally travel in the same direction and are separated by lanes. Rollovers are serious incidents that are often associated with speed or vehicle instability but do not occur as commonly as rear-end collisions.
