Linuz Myrås Fält would have taken the bus home to Bäckefors from Bengtsfors.
He hopes to be able to sleep with a friend or get a ride home instead.
- It will work out, he says.
School bus cancelled
The municipality of Bollebyg announces that the afternoon school shuttles have been cancelled.
"When we cannot guarantee the safety of driving a school bus, the responsibility for picking up the child passes to the guardian."
writes the municipality on its website.
The rescue service: May be slippery tomorrow as well
The emergency services call for caution in traffic during the night and morning.
- The worst is when it changes in the evening and gets cold.
For those who rush to work early in the morning, a sudden slip can be a concern, says Niklas Fredriksson, force leader at the Rescue Service in Åmål.
