Tens of thousands of drivers have been ignoring Springholm’s controversial traffic lights.
The signals are designed to change to red when traffic travelling above 30 mph approaches.
However, figures from Scotland Transerv show that more than a fifth of traffic isn’t stopping when the red lights are showing – nearly 18 months after the system was installed.
Galloway and West Dumfries MSP, Finlay Carson, said: “Running the red lights is still happening on far too frequent a basis and those doing that should be toughly prosecuted.
“The lights should only be a temporary solution ahead of bypassing the village.
“The solution is not only about controlling speed, it is also about a positive way of life for those living in Springholm.”
Springholm road safety campaigner accuses authorities of "deliberate falsehood" over speed figures
Officials from Scotland TranServ, Transport Scotland and the police recently organised a meeting in the village to update residents on how the system has been working.
Their stats showed the lights had led to a drop in average speeds at the four locations in the village they had been monitoring, although it was still above the 30mph limit in some places.
Their figures also revealed that since the lights were installed in late 2017, they have been activated by speeding vehicles more than 370,000 times.
And on nearly 80,000 occasions, people have run the red light.
Springholm road safety campaigner claims village traffic lights are "hopeless"
A Scotland Transerv spokesman said: “The Transport Scotland and Scotland TranServ presentation, and the success of the Springholm lights was widely welcomed by local residents who appreciate that the road safety project has helped to significantly reduce the number of drivers speeding through the village.
“The large majority of drivers use the lights correctly but we are currently working with Police Scotland to more directly address motorists who speed through the village.
“Not only are they ignoring road traffic legislation but also endangering other road users.”
A police spokesman added: “We acknowledge the work that is ongoing with partners to resolve the issues arising in Springholm.”
Mr Carson is set to meet with road safety campaigners in Springholm in a bid to find a way forward.
