The accident occurred in connection with a larger traffic control at 5 pm on E6 near Hogstorp in Uddevalla municipality.
Due to the control, queues had formed.
According to the police, the man who drove the truck probably missed this and collided with the passenger car that the woman was traveling in. The woman's car then collided with the car in front, and it then collided with the next car – but no other person is believed to have been seriously injured.
He is suspected of reckless driving and causing bodily harm.
He is identified, heard on the spot and will be heard later as well. But no one is deprived of their freedom, says the police's press spokesperson Göran Carlbom.
According to the Swedish Transport Administration's website, the road is closed in both directions until 11 pm on Wednesday evening.
