A speed survey ordered by a concerned council has revealed that more than 70 per cent of motorists broke the limit in a residential street.
Duston Parish Council commissioned the traffic survey to look at speeding in four streets in the area which have 30mph limits.
And although it is still analysing the full results, 78 per cent of the 2,800 cars checked in Weggs Farm Road were driving in excess of 30mph.
The survey took place between Wednesday, November 7 and Friday, November 16, and also included Main Road, Wrenbury Road and Cotswold Avenue.
Duston Parish Council chairman, Alan Earle, said it was an urgent safety issue which needed bringing to motorists’ attention.
He said: “We’ve not had a chance to do a full analysis yet but Weggs Farm Road came up as a big red flag.
“At this stage it is just warning people rather than taking enforcement action.
“There are a lot of families along there and we want to make people aware.”
Northamptonshire County Council carried out the survey, and the parish council is inviting a representative to its next full council meeting to discuss the results.
A county council spokesman said: “We take all incidences of excess speed very seriously and investigate for possible solutions.
“This is a matter of working with communities and our partners to identify appropriate measures.”
