All vehicles are susceptible to rollovers to various extents. Generally, rollover tendency increases with the height of the [[center of mass]], narrowness of the [[axle track]], steering sensitivity, and increased speed.

The rollover threshold for passenger cars is over 1 g of lateral acceleration. [[Light trucks]] will roll over at lateral accelerations of 0.8 to 1.2 g. Large commercial trucks will roll at lateral accelerations as low as 0.2 g.<ref>{{cite web |url=http://deepblue.lib.umich.edu/bitstream/handle/2027.42/1290/93802.0001.001.pdf;jsessionid=B5253DBD8EF2E32C517A7EEB6CDC1BE5?sequence=2 |title=Rollover of Heavy Commercial Vehicles |author=C. B. Winkler and R. D. Ervin |publisher= The University of Michigan Transportation Research Institute |year=1999}}</ref> Trucks are more likely to roll over than passenger cars because they usually have taller bodies and higher ground clearance. This raises the center of mass.

[[sport utility vehicle|SUV]]s are prone to rollover, especially those outfitted with long travel off-road suspensions. The increased suspension height for increased clearance off-road raises the center of mass.

[[Full-size van]]s do not usually have off-road suspensions, but their increased body height makes them more prone to tip. Fifteen passenger vans such as the [[Ford E-Series]] (at 27.9%<ref>{{cite web|url=http://www.safercar.gov/Vehicle+Shoppers/5-Star+Safety+Ratings/2011-Newer+Vehicles/Vehicle-Detail?vehicleId=6394|title=2012 Ford E-150 Passenger VAN RWD|publisher=U.S. Department of Transportation|access-date=2015-09-16}}</ref>), are particularly notorious for rolling over because their height is increased by the heavy-duty suspensions necessary to carry large numbers of people. The rollover tendency is increased when the vehicles are heavily loaded. It is recommended to not load anything on the roof of such vans, and to use drivers experienced or trained in safe operation of the vehicle. In such cases, familiarity with the vehicle's behavior loaded and unloaded, avoiding sudden swerving maneuvers, and reducing speed through tight turns can greatly decrease the rollover risk associated with these vehicles.

Manufacturers of SUVs often post warnings on the driver's sun-visor. Among the vehicles which have received publicity for tendencies to roll over are the [[Ford Bronco II]], [[Suzuki Samurai]], [[Jeep CJ]], [[Mitsubishi Pajero|Mitsubishi Pajero/Montero]], and [[Isuzu Trooper]].

Military vehicles have a much wider wheel track than civilian SUVs, making them more difficult to roll over. However, [[Improvised explosive device|IED]]s in Iraq and Afghanistan cause roll overs not seen by civilian vehicles. The top turret gunner is particularly vulnerable.<ref>[http://www.oregonlive.com/special/oregonian/iraq/index.ssf?/special/oregonian/iraq/or050525.html "Iraq rollover kills Oregon soldier" Oregonian May 25, 2005 by MIKE FRANCIS]</ref>

A tall passenger coach made US headlines when 15 passengers were killed [[World Wide Tours bus crash|in New York in 2011]]. The bus swerved, flipped on its side and hit a pole which split off the top of the vehicle.<ref>[https://www.latimes.com/archives/la-xpm-2011-mar-12-la-na-new-york-bus-accident-20110313-story.html March 12, 2011 By Geraldine Baum, Los Angeles Times]</ref>
