The only speed activated traffic lights in Scotland, based in Fairlie, have been out of action over three days.

The lights were switched off on Wednesday as BT Openreach were due to be carrying out works at the scene.
A Scotland TranServ spokesperson said: “Our contractor is on site today to reinstate the lights, which were earlier switched off to allow for utility works. 
"These works have since been postponed and the lights restored to a permanent working order, further to initial trial.”
The traffic lights were installed at The Causeway junction on the A78 in 2014 and are designed to turn red if a car is speeding at over 30mph through the speed sensors located nearby.
The move was initiated following a campaign by a safe roads group in the village.
