Traffic lights across Glasgow are out following a surge in power overnight.
Around 98 out of 365 controllers across the city are down.
Engineers are currently out fixing the problem which the council hopes to resolve before lunch time.
The issue is due to a spike in electricity at 2am on Friday.
It follows a traffic light outage in June which was also caused by an overnight power surge.
Glasgow City Council at the time urged drivers to be cautious.
The local authority has been approached for comment.
