A study by the European Transport Safety Council found that in a collision between a modest-size SUV (sports utility vehicle) weighing 1,600kg and a lighter car weighing 1,300kg, the risk of fatal injury decreases by 50% for the occupants of the heavier car but increases by almost 80% for the occupants of the lighter car. Similarly, pedestrians and cyclists are more likely to be killed if the car that strikes them has a bonnet that is higher off the road than average, a typical feature of an SUV.
