The wheels have been set in motion on a bid to ban HGVs weighing more than seven-and-a-half tonnes from the road linking Sidbury and Sidford.
Councillor Stuart Hughes wants the weight restriction to be imposed on the A375.
It would run from Sidbury the traffic lights junction at Sidford Cross.
HGVs exceeding the limit would have to follow a diversion route – possibly via Daisymount, says Cllr Hughes.
Such vehicles would not be prevented from making deliveries.
The mooted restriction would be signed from Honiton and Putts Corner to the north and at Sidford Cross to the south at the A375 junction to the A3052, near the Rising Sun pub.
Cllr Hughes said ’40-tonne’ lorries have been known to use the route to travel into Sidmouth.
He added: “There has been considerable concerns expressed by the local residents and especially those who live adjacent to the highway of both Sidbury and School Street, Sidford, over the increase in HGVs using the A375 route through their communities.
“Further increases on the unsuitable sections of highway with narrow pinch points was a reason the county council objected to the application for the B8 distribution element of the business park application on the outskirts of Sidford.
“Whilst the Government’s planning inspector allowed the appeal, he did however refer to the problems further HGV movements would cause and it therefore makes sense for a 7.5-tonne restriction to be applied.”
Cllr Hughes cited both Honiton town centre and Lyme Regis, on the A3052, as both having 7.5-tonne restrictions, except for access.
Diverted HGVs here use the A358 from Axminster to A3052 Boshill Cross.
Cllr Hughes said Devon County Council officers are now looking at his request.
