A new speed camera is set to crack down on racing drivers from next week.
The fixed speed camera has been installed on Main Road, Cardross, and will begin enforcement from Monday to tackle the problem.
Surveys showed 56% of vehicles on the road were travelling above the 30mph speed limit, said Police Scotland.
The busy road connecting Dumbarton to Helensburgh sees a heavy volume of traffic going through Cardross.
Police said the site was highlighted during a Safety Camera Scotland site selection.
There were nine injury collisions recorded over a five-year period and Argyll and Bute Council introduced high-friction surfacing and barriers to improve safety.
But the speed surveys still found 56% driving above the speed limit.
So the decision was taken to introduce a fixed speed camera to reduce the number of collisions and target those going too fast through Cardross.
Inspector Bart Simonis, area inspector for local policing, said: "Road Safety remains a local policing priority across Argyll and Bute.
"We have been working closely with a host of partners delivering various initiatives and events to improve decision making and influence driver behaviour across our communities.
"We are fortunate to have our specialist Roads Policing officers based locally who continue to supplement and support local policing. I know the community of Cardoss are fully behind this enforcement plan and we look forward to seeing an improvement in driver behaviour."
Alan Bowater, area manager for the West Safety Camera Unit, added: "Motorists need to be reminded that they should drive cautiously and at a moderate speed through villages, and the effective placement of the fixed speed camera should act as a deterrent to those driving at inappropriate speeds.
"Drivers who continue to travel at irresponsible speeds through this residential area will face a £100 fine and 3 penalty points."
