What the Mercedes-Benz GLB-Class death rate means
A driver death rate of 0 means IIHS found too few driver deaths in 2020-23 Mercedes-Benz GLB-Class 4WDs, relative to how many were registered, to separate the rate from zero. It does not mean nobody can die in one. The 95% confidence interval runs from 0 to 29, so the true rate could plausibly be as high as 29.
The other-driver death rate of 28 measures the opposite risk: how many drivers of other vehicles died in crashes with a Mercedes-Benz GLB-Class. Its 95% confidence interval is 0β62. It is higher than the Mercedes-Benz GLB-Class's own driver death rate, the usual pattern for this class. Remember that death rates describe vehicles and their drivers together: IIHS adjusts for driver age and gender, but not for where or how carefully people drive. Our score weights this model's own rate at 70% and its class at 30%; see how we rank used cars.
