Abstract
Yearly many police cars, ambulances, fire engines and other emergency vehicles are involved in accidents even when their special horns and blue rotating lights are working. For those emergency vehicles it is necessary that they can arrive at their destination as quick and safe as possible. Therefore the legal measures for the horn and rotating light were introduced. But it is shown that these measures can not guarantee a safe passage, in particular in the nowadays high traffic concentration. Measures for the road safety of these vehicles are discussed.
