Rollover crashes (ROCs) are responsible for almost a third of all highway vehicle occupant fatalities. Although ROCs are common and serious mechanism of injury, ROCs are under-reported. To analyze the causes, mechanism, impact and prevention of ROCs, we reviewed the literature between 1984 and 2013. By utilizing the search engines PubMed, MEDLINE and EMBASE by using key words "ROCs" "Ejection" and "vehicle" the initial search yielded 241 abstracts, of which 58 articles were relevant. Most of the articles were either retrospective or experimental studies funded by automobile companies. All vehicles are susceptible to rollovers to certain extents. Despite continuing innovation in vehicles' safety, human factor is pivotal in prevention of ROCs. Distracted driving, speeding and drinking escalate the chances of rollover crashes. Wearing a seatbelt greatly improves the chances of surviving a ROC.

Due to increasing mobility and energy conservation needs, improving bus and coach safety without adding weight is essential. Many crashes with fatal outcomes for vehicle occupants are associated with the rollover of the vehicle, revealing the structural weakness of the steel pillars between windows, which must resist high levels of bending during rollovers. This study aims to reinforce these pillars with expired carbon fiber prepreg from the aircraft industry, improving safety and reducing environmental waste.

Objective: The effect of shoulder-belt load-limiting was evaluated on right-front passenger kinematics in 90 km/h oblique OMDB (offset moving deformable barrier) impacts and compared to kinematics in 56 km/h NCAP crash tests. The study focused on the influence of webbing pulling out of the retractor increasing forward excursion of the upper torso and head.
Methods: 18 OMDB crash tests were conducted by NHTSA at 90 km/h.

Objective: The effect of ESC (Electronic Stability Control) was investigated for the rate of crash exposure, serious injury and fatality in pole and tree impacts. Field data was analyzed by crash type (front, side, rear and rollover) and model year (MY) before, during and after the implementation of ESC.
Methods: The number of pole and tree impacts was determined for four groups of vehicle model years (MY): 1981-1989 MY and 1990-2002 MY before the introduction of ESC, 2003-2009 during the phase-in of ESC and 2010-2020 MY after essentially all vehicles were equipped with ESC.

Objectives: Due to their relatively complex roadway characteristics, horizontal and vertical curve segments are associated with decreased visibility and a higher risk of rollovers. Multiple studies have identified the associated risk of young and older drivers separately in such complicated driving environments. This study investigated the relationship between driver age and injury occurrence from crashes occurring along curve-grade combined segments.
