Clare Town Council is drawing up plans to carry out a survey of the lorries which pass through the area.
The authority wants to establish just how many HGVs are making deliveries in the town and those which should use an alternative route.
It is hoping to set up laybys at entrance and exit points to find out where lorries are going and where they have come from.
“We want to get a definitive answer on what lorries could avoid coming through Clare and the ones which need to,” said Keith Haisman, chairman of the council.
“If we stop lorries in a layby and ask where they are going, that would tell us.”
Mr Haisman said the advantage of the survey, compared with CCTV, was that drivers could not say they were making a delivery if they got stuck in traffic.
“We are currently trying to find adequate locations for the laybys and are working with the county council to find a solution,” he added.
