The risk of fatal rollover of utility vehicles per 100,000 registered vehicles relative to cars during 1982-87 was strongly correlated to the static stability of the vehicles. Distance between the center of the tires divided by twice the height of center of gravity explained 62 per cent of the variation in fatal rollover rates where rollover was the first harmful event. Statistical controls for 20 major risk factors indicated no correlations that would deflate the correlation between stability and rollover. Low stability utility vehicles roll over more often on the road suggesting that the lateral force of turning is often the tipping force.
1982年至1987年间，多用途车辆相对于汽车每10万辆注册车辆的致命翻车风险与车辆的静态稳定性密切相关。轮胎中心之间的距离除以重心高度的两倍，解释了翻车作为首要有害事件时致命翻车率变化的62%。对20个主要风险因素进行统计控制后发现，没有任何相关性会削弱稳定性与翻车之间的相关性。稳定性低的多用途车辆在路上更容易翻车，这表明转弯时的侧向力往往是导致翻车的力。
