Abstract
Yearly in the Netherlands, about 1200 vehicles fall into the water, out of which 80 to 100 occupants are killed. Investigations done on this subject showed that a) a vehicle fallen into the water can already be vacated in several ways during the drifting b) the construction and equipment of the vehicle are of influence of the bearing and on the escape of the occupants c) the use of safety-belts has a favourable effect d) the doors of the inside of the vehicle are never to be bolted during a drive and e) in most cases in the drowned vehicle will be no air-bubble at all.
