It was above all the difficult weather and snow slope that caused the two mass covers, Bengt Olsson tells SVT News.
– The accident on the E4, there was a yellow weather warning there and snowfall all the time. We had fought slip there just before. But something happens to a car and then there will be consequence. What does one or the other can be discussed, he says.
Just as the accident at the E4, the Swedish Transport Administration believes that it was caused by the weather conditions on the E18.
– On the E18 it was the same phenomenon but no yellow weather warning but there was snowfall which then led to the crashes, says Bengt Olsson.
The accident caused major injuries and over 100 people were taken to hospital.
– Probably one of the major accidents in Sweden, says Bengt Olsson.
Rapid changes in road conditions
The Swedish Transport Administration had fought slip both the E4 and E18 before the accidents but in this case it was not enough. According to the Swedish Transport Administration, there are several things that can affect the anti -slip.
Salt crystals can blow away in strong winds and in some cases the control stops working when the temperature drops for eight minus.
– The more cars that drive on a slippery surface are polishing the surface, says Bengt Olsson.
He also explains that road conditions change rapidly in the Swedish winter weather, which makes the car driving difficult.
– It can switch in a minute, says Bengt Olsson and continues.
– The only thing you know is that it will not be the same road when you go out as when you arrive.
He therefore urges motorists around the country to pay attention to local weather broadcasts on the radio and adapt the driving to the road.
– The most important thing is that you adapt the driving and keep an extra long distance.
Extra busy during the sports holiday weeks
The sports holiday weeks have started around the country and the roads are therefore extra charged when the Swedes are going to reach northern latitudes. According to Bengt Olsson, all northbound roads in the country will be affected.
– On these roads you will not be alone, says Bengt Olsson.
