You'll usually see it in a police crash report, an insurance denial letter, a tow-yard invoice, or hear it from an adjuster saying the vehicle "rolled over" or "experienced a rollover event." That means the vehicle tipped onto its side or roof, or fully flipped one or more times during the crash. It does not have to spin end-over-end to count. If the tires leave normal contact with the road and the vehicle turns onto its side or over its top, that is a rollover accident.

These wrecks are bad news because they turn a normal crash into a crushing, ejection, and roof-collapse problem. Seat belts, airbags, roof strength, speed, cargo loading, tire condition, road edge drop-offs, and steering inputs all matter. On roads like US-33 through Hocking Hills, curves and elevation changes can set up a rollover fast. On I-90 east of Cleveland, lake-effect snow can do the same when a driver overcorrects on a slick surface.

For an injury claim, a rollover usually raises hard questions about fault, comparative negligence, product defects, and whether the occupant was wearing a seat belt. In Ohio, modified comparative negligence under Ohio Revised Code 2315.33 can cut damages if the injured person shares blame, and bars recovery if that share is over 50%. A rollover can also support claims against a manufacturer for roof crush, tire failure, or a bad stability control system if the evidence backs it up.
