More than 100 drivers have been caught speeding under the Kingsway’s new limit in the month since it was introduced.
Transport Scotland reduced the speed limit between the Forfar Road junction and Kingsway East Retail Park, in Dundee, from 50mph to 40mph on February 10.
Between that date and March 18, 131 drivers were reported for going over the limit 129 of whom would not have faced prosecution under the old limit.
Tayside Safety Camera Partnership is responsible for monitoring the road and partnership manager Arron Duncan said many of the speeders had been caught by the group’s mobile cameras.
He believes the new lower speed limit will improve safety but said that despite significant advertising and new road signs a number of drivers had failed to appreciate the change.
“The likely reason for this happening is because people have not been paying attention to the signs on the road.
“The reduction in the speed limit was well advertised and I would think much of it has come about due to habit.
“I would suggest that people make sure they are aware the speed limit on the road has reduced and drive accordingly, just like they should do on any road.”
“In my opinion the reduced speed limit will make the road safer because, at the end of the day, that’s why it was brought in,” he said.
The figures, revealed by Police Scotland, showed that the highest speed recorded over the time was 67.9mph.
The force added that “speed is a key contributory factor to the seriousness of road accidents and the level of injury sustained and consequently any action which would cause individuals to drive at speeds in excess of the speed limit must be considered inherently harmful”.
Tayside Division said: “Police Scotland reminds motorists to be aware of the speed restrictions in place and drive accordingly.
“Officers continue to monitor the area as part of policing patrols and anyone found committing offences will be dealt with appropriately.”
The limit was reduced following a review by Transport Scotland, which concluded the move would improve safety.
