The trams are called the yellow danger, because there is so many accidents with cars and trams. Mostly it´s people who dont live here that are involved in accidents becaus they are not used to meet a tram on the road.
If your driving in Norrköping beware of the trams, you must always stop and let the tram go first if there isn´t trafficlights.
In Norrköping the Tramway has the right of passage in every crossing, people not used to drive in Norrköping has been in a number of accidents with tramways. Fortunatly they have made the most dangerous crossings safer by installing redlights.
But if your driving in Norrköping and have to driva across the tracks take your time and make sure there's no tramway in sight. It's a reason they are called by locals the "yellow danger" (Gula Faran).
Nothing realy dangerus but some youth gangs looking for fights or to robb an easy target mostly on weekends around the nightclub area and around the city
but if you take normal precaution not getting to drunk
flashing your cash you will be safe in Norrkoping.
