The number of road traffic fatalities in Germany decreased steadily until 2010. However, since then the statistics show that the number of collisions are on the rise again. Reasons for this trend can be found, for example, in increased traffic volume, stress in everyday life or distraction whilst driving. As a result, dangerous situations on the road are often not assessed correctly or are recognised too late by road users. This shows a need for action to break new grounds in road safety work. This is exactly where gefahrenstellen.de (dangerspots.org) comes in.
